Shocking Revelations!!!!

[The Nutty Professor]

After a little research I found out one thing...Fox Shock’s just about rule the mountain bike rear suspension market. There are other manufacturer’s of course but their range and price of shock’s is limited. They have expensive and unobtainable. I have added shock's from as many reasonably priced sources as I can. Some of them you will look at and wonder what I was thinking, but they was a little method to my Nutty Professor ways. If I show you the shock here and the going rate you might find the exact same shock on SleazeBay for a price you find acceptable. I also placed links to the parts companies so that you can check the specs for yourself and I could keep the thread smaller. If I posted the specs the thread would read for pages before the first reply. OK why do you need a rear shock other than the one the company "slapped" on there? For one if your ride is to rough the OEM shock will probably not have a setting soft enough for you. A MB shock will. The second thing if you like racing your buddies on the weekend the factory shock is a boat anchor for dragracing and course racing. In dragracing the shock won’t let you use all of the rear tire because you can’t dial into the track or street conditions with the OEM P.O.S. With a MB shock you can use one two three clicks and you’re there. The real test is the road course. The OEM shock wallows around like a fat chick on greased plastic (Hog Slaying for the weaker stomach’s). Dial the shock to it’s stiffest point and you might as well have a metal rod instead of a shock at the rear. The tire slides and won’t hookup or grip and slides until finally it throws you on the ground. If you have it too soft you get the wallow and your butt comes off the seat, your feet slide off the pegs and generally you get stuffed in every corner and out run on every exit. The first thing you want to change is the motor, because with more power "I can outrun the sucker’s on the straight’s"! Then after you spend your money and bust your knuckles through the install process you still get raped on the track so you still work on more power. It’s a never ending cycle. What would have probably solved half your problems would have been a decent working rear shock. A good shock allows you to put the power you have down on the road. If the tire is bouncing off the road it’s not putting the horses down on the asphalt. It the rear is going sideways it’s not pushing the bike forward. Even you guys looking for "TOP SPEED" might think about this. When you’re running flat out and your tire stops flexing it starts spinning and you lose forward motion. A shock (A good one) will help even a bad tire deal with some of the force it can’t handle...To Be Continued?

I'll list the responses to the thread next

[The Nutty Professor]

Swheels...To me thats one of the best upgrades you can do to these little bikes.I say this because you will feel more safe and secure on your bike even if your just cruisin.Like the nutty professor said the all the horsepower won't help you in the turns.If anything it will make things worst.


D h...yeah between the tires and the suspension i dont feel too safe diving into a turn at 30 much less 40, i can just see my ace skiddin down the street into the ditch


Swheels I don't mean to laugh.LOL but i could see that happening.Because it happen to me.I slid into a curb comeing out of a high speed turn.Both wheels broke traction.I had the best crashes on my x7.LOL

D h...1 of the times i wrecked was on my x1 when i was turning onto a street that had water that had ran over it about a foot wide from some1 washn there car and right when the front wheel hit it slid out and the next thing i know i was sliding on my hands and knees, its funny now but rode rash on ur hands is not a good thing, i jumpd back on and went home b4 some1 saw me


The Nutty Professor... Shock length does it matter?????

I was reading through some back post and found a few people who listed the length of their rear shocks. But there were too few measurements to know if what they put down was common or what was thrown onto their bikes. The measurements I got were between 5.5 inches and 6 inches? If that’s the case most MB shocks appear to be to short, but I then went back and read a few of Swheels post were he writes about moving his forks up inside the triple clamps. If that’s what has to be done for more turn in control then adding 1 inch to the rear is what you probably need to do first. If the shock is longer (Than 1 inch) and can't be adjusted to lower it then moving (Re-welding) the shock mounting point might be the best option. That might seem a bite drastic but think about it like this. Once the mount is moved any shock that matches the length of the shock you are trying to fit is now an option. Your shock selection goes way up. This was a short segment (Pun not intended) so I’ll see about putting more in the next one. I think air versus coil spring will be next...To Be Continued?


Swheels...Well i went and took some measurements.The x15 shock is roughly about 9''(shock was still mounted on the chassis).The x18 5.5''/6'' and the x7's with the uni link rear suspension is 6''.which by the way i can't wait till i change it over to my x18.........For the x6,7,8,1and2 i believe are 4''.

Most of the really good mtb shocks 7'' and up more choices.So is the price too


The Nutty Professor... A 4" shock! That must be a steel rod with a spring on it! Yeah the price's can be up there, but if you can find a clearance shock or a SleazeBay deal sometimes you make out alright.
/COLOR]

[COLOR="Purple"]Blitz...my 15 shock inst adjustable at all but its springy
id like to paint the spring, does it come apart?


The Nutty Professor... I would not recommend it unless you have a spring compressor. But to answer your question I don't know but probably not. Most production units aren't made to be rebuilt and if you can't rebuild it usually you can't take it apart and put it together again.


Swheels...The x15 is the only xbike that i've seen that you can't take the shock apart.That spring is for some small automobile.I think it was from Le car some of you kids might not of heard about that car.But if you find ONE it might be worth a million dollars.


Bri...Here is a bit of info on shock length. I purchased a 150mm MTB shock off of ebay and installed it last week. You can find shocks that are closer to the stock shock lenght but I didnt see many available at the time. This raised the rear about 1/2 an inch or so which I was excited about cause I always felt the rear end was to low.
The problem I ran into is the chain now rubs on the swing arm pivot point. (no matter how you adjust the chain or shock it will happento some extent if you use a 150mm or longer shock) Remounting the shock mount would be a great fix for this problem.

Now the spring I got was rated at 750 lbs which after doing some math I thought would be ok for my application, I weigh 200 lbs and that spring is just not stiff enough to support my weight with out the rear end hopping a bit in the turns, so if you are a heavier rider be sure to go with a heavier rated spring on the shock. To fix this I order a 1500 lb spring to replace it (same shock just new spring) I am definitly going to remount the shock mounting bracket to try to get the rear end back to a stock height.

I have spent hours testing this and totally agree with Hglenn that the MTB shock is the way to go. Just be sure to get the appropriate spring weight and make sure you get the length figured out the closer you can stay to stock lenght I say the better.

Swheels...Just off of the top of my head i'm gonna guess you have an x18?.......It's very rare to find a 5 1/2in mtb shock.The one i've found is the marzzochi air shock and it's a older version.It was a great shock but i played with it so much that after a few laps it loses a little air pressure.I've mention it before but i'm gonna put the x7 uni link setup on my bike.That way i can run a longer shock and not have to worry about the rear of the bike riseing plus it will give the bike better traction.I don't know why they stop making that setup.It was the best!


The Nutty Professor... Why I keep forgetting things that I should remember??? If you raise your ride height enough in the rear you will have to either shorten or lengthen the chain. This fact is mostly due to how the rear geometry has changed and in what direction. With no links in these systems I thought the shock deal would be easier but I can see it isn't. I also wondered about the spring rate and you have answered that question Bri.


Bri...Even with a shortened chain (which I had to do when I changed my gearing anyway) a shock mesuring over 130mm will still rub on the rear swing arm axl. I am in the process of rewelding my shock mounts to get back to that original ride height so I can eliminate the problem. It is an x18 and like Swheels said the stock shock is about 5 1/2" eye to eye (and I use that term loosely) So if you are looking to do a rear shock upgrade and dont want to mess with the shock mounts get about a 5 1/2" MTB shock (130mm) I didnt find one that had the features and price that I was specifically looking for. I am sure they are out there if you look.

Oh and Swheels I agree with you a uni shock set up would be awesome, please post some pics once you get to that project!!


Bri...Well my rear suspension mod is finally complete! First off I remounted the top of the rear shock on the opposite side of the frame (engine side) this allowed me to return to stock height and have a better angle for the shock. The 750lb spring that came with my new MTB shock was just way to soft. I had a couple different people sit on it and even a 165lb rider could bottom it out on a big bump in the road. I bought a 1500lb spring to replace it. I had to cut down the spring to fit it on to my shock (tried spring compressors but the automotive ones where just to big) with a few quick adjustments on the spring tension nut I now have it perfect! Nice and firm and no more bouncing coming out of the tight corners. I will try to get some pics up once I have time.


Swheels...What kind of shock did you get? Becuase if you got one with adjustable bound or rebound it will help out plus adjusting the spring preload.Never mind i getcha.
I had a long battle with my rear shock and i won by luck though.I took a chance and took the shock apart.Not knowing if i could get it back together or atleast to work properly.It oil dampen/air or nitrogen charged.well it's air charged now for sure.Well i wanted to get even better dampening without having to play with the adjuster knob so much.SOOOooo i put some heavier oil in.LOL gear oil LOL.Low and behold it worked and better than it did when it was brand new.I botched up the valve a little when i was putting the air in the upper chamber.So i took apart the upper chamber and cut a piece of inner tube.Then placed it so it would act like a check valve letting the air in.But stop it from coming out.I must of step in some dog poop cuase it worked.Nows me happy again.I'm getting ready for july 14.

Btw post up pics ooh i almost forgot check this shock out it's like the one i have now just different mount.I'm interested in this shock because of the way it mounts up.With some mods you can also use it to adjust the rear ride height. That would be really tricked plus i think i seen it for hold on now 9.99 dollars.

Red...I found these DNM shocks. Pricey, but available in various lengths and fully adjustable.

http://www.cyclelink.com.au/category141_1.htm

I like the ST8-RC myself.

Cheers,

red

Edit: Checking details they are available with 6 different weight springs.


The Nutty Professor... Have to agree with Red on the shock. It's got adjustments out the wazoo and real purrdee. The spec say most of it.

Air/Oil/Coil Spring
Adjustable: Compression/Preload/Rebound
Capacity:1100lbs
Length:210mm

JagSpeed...I used a Fox Vanilla MB shock on my X18 it works great. The stock shock measured 5 1/4 in. The Fox is 5 1/2 in. the 1/4 in. longer shock raised the rear 1 in. I used the stock X18 1500lb spring on the Fox shock. I also put 1/2 in. spacers in the forks to help stiffen the front end.
I can actually go fast on a road course now with confidence the bike handles so much better.

[The Nutty Professor]

Most people know I've got it but I have to show it off. I'm already looking at upgrading it to with a titanium spring, but that will have to wait until I see if it meets my expectations.

[stuntnx7]

i need to get something for my x7....when i try to do balance wheelies my swing arm is moving to much....how much is that one

[The Nutty Professor]

It's priceless home-p finding one is the problem. If you're stuntn you don't need it. Buy a decent mountain bike shock off ebay and call it a day. But make sure the spring weight is at least 750lbs more would be better but less is not.

[stuntnx7]

yeah i know bout those shocks but i want one i can race with too....i can do both so if im stuntn and a race breaks out i wanna be able to roll right up to the starting line....rock2...

[stuntnx7]

idk now that i see how cheap i can get one of those Mountain bike shocks for i might just get it....so you say 750 or more huh....whats the one you got rated at....

[stuntnx7]

well i put a bid in on a shock with a 750 lbs spring so we'll see if it works

[swheels]

Can't to see how that shock works.I was thinking about how it will do on roadcourse.thinking_smilie I wounder if it will suit my style of ridingthinking_smilie

[The Nutty Professor]

It reacts to the speed of the compression and rebound. The computer has a preset range and the shock works from that. It learns to modify also. It has three settings soft, hard, and smart. On smart it uses a electric valve that closes or regulates the opening as needed. I could go on but I'll wait until I have a riding opinion.

[swheels]

I Think it will work great for ya Np.thumbsup2

[Blitz$M.Inc.$]

man thats gonna fit perfect on a x15
that would not fit a 18 stock, i dont know bout the 22

[The Nutty Professor]

Oh it's gonna fit come hell or high water cowboy

[schofell84]

have you tried a longer travel shock and then just setting it up with more sag? (less preload)

[The Nutty Professor]

I have the K2 but that does not mean I sit on tech and don't expect it to go farther. I may have found more. This is a write up from PopSci and I still have more to do regarding research on this one.

Full-suspension mountain bikes are a relief for downhill trail riding, but their cushioning effect saps efficiency from your uphill slogging. Until this year the best solution was high-end shocks that can be manually deactivated when performance needs to trump comfort. Enter the Fox Brain Shock, available exclusively on the Specialized Epic. Created jointly by the shock specialists at Fox Racing Shox and bicycle manufacturer Specialized, the Brain is equipped with a ball-bearing inertia valve that responds only to forces that come from below. No matter how hard you stomp on the bike or its pedals, the suspension won't budge, giving you maximum pedaling efficiency. However, when one of your wheels slams into a rock, the inertia valve opens and the suspension kicks in. The result? Epic scoots uphill and across smooth terrain with the speedy efficiency of a hardtail bike, but still soaks up the rough stuff like a champ

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/7488_1.jpg

My one concern is that it seems like it's designed to make a bike a hardtail until it hits a high frequency bump then it reacts. If that's the case it's not Mid Bike material but I'm still looking at it for now.

[Blitz$M.Inc.$]

active suspension rox

[swheels]

I can see the price ton that one.speechless33

[The Nutty Professor]

I think the one I saw (The one is the photo's) on ebay was listed at like $325 or $385 something like that dunno

[Kurlon]

An alternate option is to spend a bit more up front and get a true drop in/no mods solution. Works Performance can build a shock to fit what ever you have. The 'custom engineering fee' is $50 over the cost of whatever shock model you're looking at, figure $250 at the cheapest, $650 if you're insane. : )

They'll start with a worksheet you fill out, this provides them the swingarm geometry, shock mounts setup, required length, etc. You also provide the bike weight, your weight in gear, ride style and skill level. They'll then turn around and let you know which shock bodies they can build from for your application, at which point it's a matter of deciding how much adjustability you're willing to pay for.

Whats nice is you can dial up the exact length you want, and they'll make sure you get the right spring rates and damping curve to match your swingarm, including mulitple rate springs if your geometry is a falling rate arrangement.

Its spendy, but well worth the cost in my book. Getting a custom unit for my 70 transformed it, they increased the length to give me the right ride height with the amount of sag I wanted, shortened the travel to match the front end, and got me a spring that could keep up with my custom swing arm. The machine rides like it's on rails.

[eriko]

Hey Guys,
What do you think of these shocks, would they work well on a x18?http://midbikenation.com/attachment.php?attachmentid=913&stc=1&d=1198787700http://midbikenation.com/attachment.php?attachmentid=914&stc=1&d=1198787714

Great info King. There's always a BUT...the chances that we can find a great deal on Ebay and make it work for a lot less is the attraction to MTB shocks. Yes it can be major hit and miss but we like the challenge (Or foolishly throwing money in the drink bluelaugh Not sure which one). I will look at the site and weight it out. I try anything once...well almost LOLOLOL

Hey "S" don't know if this will help but I thought you said you have a army of Fox Shocks.

Here's manual's for all there products. If that's not it here's where I got it ffrom and they have link's to other shock manuals. I'm trying to find a manual for my K2 without much luck but I'm stumbling across info other people can use.

ok so im looking through the shocks on tbolt and i see that there is two kinds: ones for A style swing arms and ones for straight swing arms
im guessing ours is a straight design
my shock is long so the pitbike shocks should work better than the mb ones right?

[The Nutty Professor]

Yeah MB shocks are going to be shorter.

[The Nutty Professor]

Now I have a question maybe you guys can answer or lead me in the right direction. I put TN back together enough to at least roll her aroung the garage. I sat on her and could immediately tell the spring on the K2 is seriously lacking. That has to be changed ASAP. I have been talking with Rene about it and here's the last PM I sent him and it explains my problem. I want to switch to a Ti spring if I can but...

"I know that Ti is stiffer than steel and need to know if there's an offset as far as weight readings go. By this I mean if you need a 325lbs steel shock because Ti is stiffer will a 300lbs Ti shock give the same result. I've registered in a couple MTB forums and asked questions like this but it's like talking to a wall. They all want to know how the newest Nike socks stack up to the old Puma??? Hardward tech seems to be beyond them. I ask and I get lot's of hit's but no answer's or even attempt's? I quess I'll have to try a few moto racing sites but I know Ti springs aren't used nearly as much."

Yes I could just buy another shock but that's not how I do business. Once I hit a wall or start seriously spinning my wheels then I admit (Until I find time to try again) defeat and buy the piece instead of making it.

Once I hit a wall or start seriously spinning my wheels then I admit (Until I find time to try again) defeat and buy the piece instead of making it. Ok i don't know if the spring rating on a ti spring is the same rating.But heres something to think about.( You might not like what i'm gonna say) try putting your stock spring on your on your k2 shock.Then mess around with the adjustments to see if you can get some kind of dampening feel.If you have your shock on the hardest setting and it still feels to soft.Then it's more than just the spring that's the problem.It's the shock internals. Like it deosn't have enough dampening for the over all weight.The reason iv'e come to this conclusion is.When i spent alot more money on a nice piggy back resevior shock with all the bells and whistles.Ok it came with a 900lbs spring i just new this shock was gonna be it.I welded up new mounts and everything as soon as i put the shock on.Then let the bike down the rear just drop.So i tightened up on the spring and made the adjustments to the last setting.Still was to soft so i put the stock 1500lbs spring on and it still wasn't that much better.thinking_smilie So then i went back to my rox shoxs That why i bought all the ones i did cause they are just that good.Believe me it was a shock to my system.LOL I ran my rox shox with a 700lbs spring and it was great.The one issue i had was with my first one i kept messing with it til i f'd it up.Then had to rebuild and expiremented with heavier wt oil.

[The Nutty Professor]

I've been eyeballing the stock spring believe me. But it doesn't look like the shock was made to be taken apart...meaning the butcher of Georgia is about to go to work LOLOL. That spring should tell me what I need to know but of course after that I wanted the Ti unit.

i dont wanna weld up mounts, wondering if they are gonna break on this turn or the next
i seen this
http://tboltusa.com/store/product_info.php?cPath=50_22&products_id=338
its just like mine cept with the piggy back
it doesnt look like it would have lots of travel, it comes with a 1k spring, think it would work?
that sux about your k2 nutty, i know you went through alot to get that, i dont know about TI but i saw these
http://tboltusa.com/store/product_info.php?cPath=50_22&products_id=358
maybe an option

[Blitz$M.Inc.$]

Sounds like you guys need Pit Bike size shocks? Have you tried some of the Pit or Tard sites?

Leave it the Mad Doctor to whip up something magnificent thumbsup2

I try Np.thumbsup2 HEy guys if they are the correct length.They should work because they're for the honda mini's so i know they will work.Also Jagspeed made i believe 2 L brackets.Then bolted them to the top stock bracket mount.A simple bolt up application.No welding....In fact i think that's the better way to go.So you don't end up on a shock with to much travel.thumbsup2

[JAGspeed@XMR]

the 15 has a long shock, like 10 inches
im still looking mishka, i had funds for one and i just couldnt decide/take the chance
i want to be sure it wont bottom out
JAG! TELL US WHAT TO BUY! PLEASE:)

I had the same issues you guys have been having when I tried to find a shock for my X15. As you said Blitz the X15 stock shock is about 10" long. Understanding suspension can be complicated. The first thing you have to determine is the leverage ratio for your bike. I think the X15 is about 3.5:1 . Second is how much travel is optimum for your application. 4.5"-5.5" usually will work ok. At 3.5:1 that means the shock will need 1.5" of shaft travel to have 5.25" of suspension travel. Third the spring needs to be stiff enough to handle the weight and ability of the rider. Fourth the dampening has to be able to control all of these factors.
I found that most pit bike shocks and mountain bike shocks 8" long and longer have 2" or more of shaft travel.
This ends up giving you 7 or more inches of rear wheel travel, which is to much for these midbikes. I used a 6.5" long with 1.5" of shaft travel mountain bike shock that has adj. rebound and comp. dampening with a 1500lbs spring on my X15. I did have to relocate the lower shock mount.
Unless you can find a long shock with the right amount of shaft travel your best bet is to make a new mount. My X18 was easy I just used a 5.5" fox shock with the 1500lbs spring that bolted right up.

Hey anybody found any new shock revelation over the past few months?

Still asking the same question. I found something but not to sure about it. I know most people are just trying to find a shock that will fringing fit without spending enough green to choke a 39mm carb. Here she is the Scott Genius TC

Those Monkey bike shocks will work.twocents

[rene13]

I found these on ebay. http://cgi.ebay.com/Brand-New-MTB-Bike-Damper-Adjustable-Rear-Shock-7-5-2_W0QQitemZ200257077323QQihZ010QQcategoryZ42317QQt cZphotoQQcmdZViewItemQQ_trksidZp1742.m153.l1262

The thing that cuaght my attention was they ask you for the measurements of the mounting points lenght, width, diameter and spring rate 500-800 lbs.

And it is 83 bucks shipped.thumbsup2

I got down and dirty and built a custom shock.I took 2 shocks made by 2 different manufactures to create 1.So now when i set the bound to the highest level and then set the rebound to the highest level.It feels like your riding a rigid frame.I Put the stock 1500lbs spring on.But i'm pretty sure i can go down to a 900 or a 1000lbs rate spring and still be real firm.I even cut down the shock body to make the shock shorter.I am very pleased with the results.There were times i wished i had a stiffer spring or shock and needed it.

[The Nutty Professor]

Look at this Frankenstein of a old school shock. That thing must weigh as much as a MTB put together lololol Not really sure how it mounts though dunno

[swheels]

HA it thought it was some type of jack.bluelaugh

[Blitz$M.Inc.$]

[The Nutty Professor]

Probably one of the first downhillers.

One of the biggest down falls living off of a sandy road.That ish gets everywhere especially when your spinning up the rear tire.banghead
