C40 seat post(6 posts)

I have a Colnago C40 with the Colnago carbon seat post. I have noticed that the pros don't use the carbon post. They run Shimano posts. I can't find any seatpost in the 28.0 size other than the Colnago carbon. I am only asking in case I need to replace. The carbon post works great. Any ideas where to find alternatives?

Not sure it's an issue (have you heard of one breaking?). Plus, the pros may have sponsorship issues. If you needed to, you likely could use a smaller post with a shim.

They make an MTB seatpost that is 28.0 size. Aluminum.

I posted a similar question last year and searched everywhere for a solution. Most people told me to cut an aluminum can and make my own shim. This didn't feel right to do to a C-40. While in Europe I searched and then I contacted all the US Colnago dealers. Finally Britton bikes had a shim. It weighs less than my wedding ring, but it has a machined look and a lip to keep it in place. I can't tell any difference in the ride quality from the carbon seat post. Sorry for the dust in the picture, but 5 knee surgeries have side lined me for now.

USE who make the Alien posts also makes a serious number of specific shims for use with either 25.0 or 27.2 posts and shown on their website. I'm sure you can order one from your LBS.
