Carbon rims

Have a look at what isn't available from a UK supplier, but that people are talking about on forums.

The new wider profile road rims for example, and the clincher 29er/cx rims.

I've got the wider 29er rims from http://www.light-bicycle.com on my 29er and I've been very impressed with them. They've stood up to serious abuse, and they're very easy to run tubeless if you fit Bontrager Rhythm rim tapes. In fact, I've got another pair of rims sat in Customs at the moment to go on my CXer.

If they were available at a reasonable price in the UK (avoiding the delays and the potential customs problems) then I certainly would've bought some.
