I think that is better than an alloy one. I had one in my Al. frame, and it simply corroded to it. Although i greased it it was a b*tch to get out! using pliers and a hammer i finally managed to do it!

Pick the plastic shim

This is for your CR1, right?

If so I think you need a 31.6mm post/shim.

I would use the USE acetal shim. Don't use an aluminum one.

ÚSE's aluminium ones are for small diameter change shims. They are not made in 31.6/27.2mm size. I use plastiqueones in all my titanium frames.

Just finished looking for shims myself. Here are some good sites for the 27.2 to 31.6/31.8 conversion:

http://www.pricepoint.com/detail/11704-275_ROCSH1-3-Parts-68-Seatposts/Rock-Shox-Seatpost-Shim.htm

http://www.excelsports.com/new.asp?page=8&major=2&minor=19&description=SX+Seatpost+Shim&vendorCode=USE

As mentioned, the thermoplastic shims look good for avoiding problems with metal frames (cold welding) and carbon frames (corrosion).

Wouldn't go for shims at all. There is enought choise in 31.6 to make a good choice. The new carbon deda (xl4 ??) in 30 cm. with setback is 160 gramms uncut and can be tuned to 145 gramms with a titanium bold. If you need a longer post the new 2004 campa record isn't a bad choice (I use it in my Scott) uncut 195 gramms.
