    offset shock bushings

    Does anyone have any experience with offset shock bushings? Also, does anyone know where I can get some?

    We are running some on my wife's bike at the moment. seem to work pretty well. The only concern would be if you already have tight tire to seat tube clearance on bottom out. Offset reducers would only make it worse.

    Here is a bit of info on one possible way to get ahold of some

    We got them from some friends who own a bike shop and they got them from a local machine shop guy. I guess they are pretty easy to make so maybe you could call around and see if any local places could make them for you

    Yup. PVD Style! A lot nicer than those silly aluminum peices.

    my friend built them in the past for a friend, the guy is still riding the same bike so they must work. i always thought it was a custom thing.

    Instead of buying a copy from this rude guy above you can buy the originals from this very nice guy that I bought mine from:

    Kevin from Steamer Industries inc
    All the info is here http://www.irishdh.com/forum2/viewtopic.php?f=2&t=13080
    btw OC Tuning wont ship outside Ireland but I will.
    If you want any further info drop me a line at
    [email protected]

    or ring on 00353851331104.

    I've used mine for a while now and I can set the rear shock at 2, 3, 4 and 5 mm offset. Excellent stuff

    Hype.....how much geometry change are you expecting from 4mm difference in effective shock length?

    FFS Ride your bike and stop thinking that a change so subtle a nasa test pilot probobly wouldnt notice, is gonna make you shred

    4mm would be over 2% difference for a 7.25" stroke shock which be between 1 and 1.5 deg difference in HA (by my quick rough calculations and depending greatly on suspension design). You don't think that would be noticeable?

    Between .5 to 2 degrees depending on the frame. Math is all hype.

    Has anyone been able to get a hold of Kevin lately? I emailed both emails and got no response.

    Bear with me...it's 1230a, and studying for a final. So I remove the existing shock bushing inserts, and put these in? Do I need a smaller sized shock bolt, or am I interpreting this wrong?

    Also, how much? Would love to try this out on my bike(s).

    If you use these bushings, doesn't it limit your travel? I mean, it causes your swing arm to be part way through its normal travel range when the shock is fully extended, right? So to get the same travel, the swing arm would have to move a little bit more than it normally does right? I would guess that depending on the bike design, that may or may not be possible. Am I understanding this right? Wouldn't that also change the spring rate (depending on the angle of the link pushing your shock for example?)

    No it doesn't limit your travel as long as you have clearance. My back wheel for example slightly touches my saddle at full compression with 2+3mm offset bushings on my large 08 DHR. But I can just raise my saddle a cm and the problem is solved. It could slightly change your spring rate curve as you are extending the travel beyond what it was designed for but I would seriously doubt you could feel this in real life. Just try it and see what you think, it's a cheap mod

    Probably worth a try, but what I need is slacker, but not lower. Anyway, The PVD website shows off all that guys creations, but I don't see where you can buy?
