I just bought this frame with plans on beginning my cat5 career with this. Does anyone remember the seatpost clamp on these frames? It's an arrow shape clamp with a rubber insert vertically along the seat tube for about 3 inches. The specifications call for a 27.2 seat post but the clamp bolt bottoms-out well before firmly clamping both of the 27.2 posts I tried.

Wel,, if the recomended post don't fit, I'd take the frame to the LBS and just try some on for size them...
