Steve Potts & Erik Koski im Album 1991 Klein Pinnacle Bright Green - Team Koski Salsa Ritchey "reverse" Storck color combo 🚴🌷

One of the reasons I started DKG was to build this frame. Don Koski was a longtime motorcycling friend from high school and was one of the people I would go 'bombing' with on Mt. Tamalpais. His family owned Viking Ventures bike shop and Don and Erik were putting together the first mountain bike parts catalog. They wanted their own product line as well, and commissioned DKG to make the Trailmaster frames. We built the frame, fork and sub-assembly fixtures and only about 100 frame sets before politics ended the relationship.

These frames featured internally butted head tubes and bottom bracket shells, 4130 tubing, TIG welded construction, an original rear dropout design that has been much copied since.

The 'Koski' fork was based on a design I had done during the Trailmaster period, but didn't have the capital to produce.
