U.S.E. Alien seat post question.(8 posts)

A reputable bike catalog states you must use a shim with your U.S.E. seat post. How it reads to me is that your bike must take a undersized seat post and you must apply a shim with it to work. But I inquired at a LBS and they said they were putting in same size post. Meaning they were putting in a 27.2 post into a measured 27.2 frame. Any info and maybe there web site would be helpful at this time. Thanks Catapult

No shim was needed on my Viner, 27.2 post has fit fine with no slipping.

USE also sells 25.0Dave Hickey

USE comes in both 25.0 and 27.2. Is the shim for 25.0? Possibly the shim is for the post to fit in a 27.2 seat tube.

right off the box mine came in - "you MUST use a smaller diameter post with the supplied shim for MTB, no shim required for road bike application."

Thanks for putting this one to rest. I will order accordingly. Catapult.
Actually, I think it is just the Suspension posts...biknben

The suspension posts require the shims for anything other than 25.0. Their non-suspension posts come in a variety of widths. Even MTB posts.

the instructions that came with mine were specifically "carbon" instructions as in they said "carbon", not "suspension." they are also explicit, "you must use the shim if installing the carbon alien seatpost for an MTB application."

pretty sure the website speaks to this point clearly.
