1988 Trimble

The Trimble Carbon Cross frame was the first iteration of the Trimble design.  This original style frame lacked the extra bottom bracket reinforcement of the later Inverse 4 frames.  The lack of reinforcement led to a flexible bottom bracket and problematic front derailleur mounting.  There were relatively few frames made in this style and they often cracked making them even more rare.  UPDATE:  We have heard from Brent Trimble that there were 8 Carbon Cross frames produced.

This particular bike features the one-piece composite bar and stem combo which was designed by Brent's brother Roo.
