Want to replace my Trek road bike seatpost with a carbon one. Any recommendations?
I'll second those who recommend the Campag Record. Especially if a fair bit of setback is required.
I replaced a Selcof aluminium post with it a year back. Although the Campag is heavier (though not by much), it makes a huge difference - much road buzz is dampened - when using my brutally stiff (Colnago) aluminium frame.
