Born on the back trails and fire roads of legendary Mount Tamalpais, the original Trailmaster® frame was one of the first mountain bikes to combine TIG welding, oversized 4130 seamless tubing, 4130 dropouts, and a 70 head tube angle, to provide for efficient transfer of power and precise handling on both singletrack and fire roads. For 2000, Koski Engineering offers the all-new Titanium version, ready to take on the most demanding riding that today's riders can dish out. Built of oversize 3A1/2.5V ANCOTECH® Ti tubing, and featuring specially machined head tubes, machined 6A1/4V dropouts, custom bent chain and seat stays, the Trailmaster® is meticulously hand-welded by Mountain Bike Hall-Of-Famer Steve Potts and is designed to fly!
