Does anyone here use a shim on a CR1 seatube? Plan to use a USE Alien seatpost but not sure whether is it recommended?

seat shim is clearly not recomended on the CR1, my bike had a sticker specific just for that, I wouldnt do it.

It would be a pain to remove if it got stuck.

Pull your post out and clean it occassionally to prevent your post getting stuck.

Get a 31.6 Alien or take something else, a shim (if so it has to be at least 120 mm long) will damage the frame.

You will ruin the frame and it will not be able to be warrentied.
- Zipp rims will break if you look at them too hard
- R-Sys wheels will spontaneously explode
- The ZG crankset will never, ever exist
- Everyone needs Lightweights, even if they're fat and old
- Parts actually made of metal are SO 10 years ago
