Introducing Treeline

Treeline SL front three quarter view

It is tempting to say we have a fat bike. Riders have been asking us for one for a few seasons now. But, what we have instead is Treeline, not just a fat bike but an all-season mountain bike with the ability to run super wide tires like most fat bikes, but also the adaptability to be a 27.5+ war horse or a long haul bikepacking rig.

Treeline can be a flat bar bike or a drop bar bike. It can run suspended or rigid. It can take racks. It can be built fully thru-axle or with QR front and rear. In short, Treeline is a fat bike worthy of being a Seven, capable of fulfilling all your winter dreams without being a just a one-season luxury.

The Treeline S is built with our Integrity™ straight-gauge tubing, ultra durable. The Treeline SL, built for long-distance comfort, features our Argen™ double-butted tubing.
