I've just had to replace the Shock Bushes on my Rize Carbon 3, after some slack appeared. The reason im posting is that the bike is only a few months old, and has not had much hard use, i have covered around 100 miles, mostly on local forrest XC style trails.

Has anyone else with a Rise had this short life span for these parts?

Excuse my ignorance but exactly what part are we referring to when you say 'shock bushes'?

Something inside the Lefty or is it some part of the rear swing arm?

I've got a Rize 3 that has about 150 miles on it but I don't think there's any play in it. I haven't hit huge jumps or anything but I do pummel through lots of rocky terrain here in PHX.

No need to Excuse yourself, i guess i was not so clear,. Its the lower bush that mounts the rear shock to seat stay link pivot (see pic). it developed about 1 or 2 mm of play in it.. Im worried that if it need to be replaces in 2 months of moderate riding, it will need to be replaced 6 times a year !!

Maybe it wasn't properly torqued to begin with so now it's shot.
It's not normal for any part to wear out that fast. :nono:

I often checked they were all tight, they always were. But i really hope that the wear has been due to this..

Just to make it clearer , the part in question is a bushing , not
a bush .
Those are in your yard . :thumbsup:

I think you will find that " Bush" is perfectly acceptable.

"bush - Pronunciation [boosh]

-noun
1. a lining of metal or the like set into an orifice to guard against wearing by friction, erosion, etc.
2. a bushing."

uummm ...... no

Really , it's bushing .
Ask any number of car , bicycle , truck (whatever) mechanic
what a bushing is referred to as and the (way) majority will
be bushing

Bush and Bushing are both correct! If u did not already, go and look at a dictionary. Or how about you look at the site where i got my replacement parts !!

http://www.mountainbikecomponents.co.uk/items.asp?CategoryID=92&Name=Strong+Bushes

"These bushes last approx 3 to 5 times longer than the standard DU type bush and the are stiffer to help stop your bolt from bending."

If the guys who make and sell these parts are referring to as "bush", then that's good enough for me!

As a mechanic... i don't care what you call it haha...
but you should note that these bushings are not always made by the bike manufacturer, indeed, they are more likely from Fox, since fox only makes one kind of mounting point for its shocks - i would not blame cannondale for this but perhaps you got a bad bushing or it just wasn't put in there right, etc.

but no, many drops, a few bottom-outs and much riding - no such problem. not even a hint of looseness on any pivots.

Replace it and ride on!

Thanks for the Info. My bike shop said something along the same lines about the parts being Fox. I have fitted a 3rd party Bush and hoop that are said to be also stronger and harder wearing, lets see how i get on with these.. Hopefully the 1st set of bushes were just faulty.

I have the same problem with my Rize One.

Can somebody say if putting the shock in opposite side will help?

thanks for the link... seems like the only solution is to replace those bushes? Can I leave it as it is? will it influence somehow on bike performance?

If i was you, i would have the worn parts replaced as soon as possible, as you don't want to risk damaging your shock or frame mounts.

I've got slack in mine, but it's on a RZ120, it has done A LOT more miles than you, i do about 100/wk, so it's easy got 1000miles on it now.

I've not bothered re-ordering a bush, mate whose an engineer hates bushing!, I've ordered 2 of these: needle bearings pivot kit They are 1/2" needle bearings, near identical to the main pivot on my old 68mm Scalpel, so they will take the abuse since they're now on the lower eye compared to the main pivot.

Still waiting for them to be delivered, will let you know when they do. See this thread for more info also Sloppy Rize 5...
