Tonton Recipe

The Geometry

We designed the new Tonton with modernized geometry that is size specific, allowing riders of every shape to fat bike.

A slack head tube angle, longer reach, and short seat tube makes riders feel their most confident on the descent.

With a steep forward offset seat tube, and shorter chainstays, maximum rear wheel traction is achieved on those nasty climbs.

The Build Kits

Built for a purpose, each part chosen by the hands of avid fat bikers.

The Tonton is paired with four piston Sram DOT fluid brakes for a consistent brake feel, even in freezing temps.

The Tonton comes with one of the top performing winter forks, the Manitou Mastodon. It is cold weather rated so that you can maximize all 120mm of travel.

With a slimmed out rear end and more room for Sram’s GX drivetrain, a narrower Q factor that facilitates a more ergonomic pedaling motion has been achieved.

The Build Ingredients

Notorious for its strength while retaining compliance, the Tonton is constructed from high grade 4130 chromoly steel tubes which are laser cut and fused by local red seal welders.

To get the exact geometry we desired, we applied additive manufacturing techniques to our seat and chainstay yokes. These 3D printing methods allowed us to reduce weight, retain strength, and increase tire clearance.
