Hi Glenn - our mechanics recommend a minimum of 80mm inside the frame but that will increase the larger the size. We've found that in most cases (for Steaths and Exocets primarily) the customer will have to cut them down to the size required due to the way the seatstays join the seat tube.
Hi again- do you also see any problem with cutting down the seatpost (ie strange butting) I only need it to be 250 long?
Hi Glenn...there shouldn't be a problem providing you don't exceed any recommeded torque settings. We've ftted lots on our bike uilds I'm sure.
Do you think this post would be ok with carbon rails? Fizik say that you should have no sharp or high pressure areas for the clamp to protect the carbon. Damn those carbon rails- pain in the arse.
Hi Pete - it's not something that's planned ... not in the immediate future anyway. We certainly haven't got any on order. Sorry :-(
Do you plan to restock/re-release the carbon version you used to do of this post at any point? Got one on one bike but want another! Cheers
Hi Ikiro - the mid point between the two clamping parts of the seat post is set back approx 1cm from the centre line of the seat post. The on-one twelfty is half an inch (12-13mm). The Thompson zero-setback is...erm...in-line.
