Bronto Bikes


Willy is our pure single speed 29er. Due to the additional clearance required for a front derailleur with 29ers, we are able to shorten up the chain stays a touch on our single speed. This will help the riding characteristics and help you grind up those hills.

29ers themselves need special tubing considerations, and working in all that tire clearance and chainstay forming requires nothing short of Todd's special powers at their best. A lot of work goes into each one of these frames, and the result - we think it's the best 29er single speed out there. Granted, there are a lot of good ones, but we think you'll like ours.
