1989 Trimble Inverse 4

This Trimble features the 3 hole drop outs and internal cable routing making it a pretty solid 1989 bike.  The components were obviously matched to the frame color with the white seat, post, crank, hubs and one piece bars (made by Brent's brother, Roo).  I would guess that the 6 speed shifter and freewheel were used because of the threaded American Classic hubs as opposed to the 7 speed shifters that would have been available.
