Aluminum Gnarvester

Big Fun on a Small Paycheck

The first aluminum 29+ on the market has hit the ground spinning!

With the wild success of our Titanium Gnarvester frame, it was only fitting to bring the geometry to aluminum offering for a price point that hasn’t been seen since the days of the original 96er!

We love big wheels and big rubber, so 29+ is a no-brainer. With up to 31″ of rollover and the nimble geometry of our 420 frame, the Gnarvester stands at the crossroads of fast and playful. Even with a rigid fork, it is capable of slaying even the gnarliest trails. For best effect, a dropper post is HIGHLY recommended!

What cranks can I use?

In order to keep a standard bottom bracket, the crank and chainring selection on aluminum Gnarvesters can be partially limited. The ideal setup is a direct-mount offset chainring in the outer position (our favorite is the RaceFace CINCH interface). This allows for the full range of tooth counts starting at 26t (even a 38t works but it’s wicked friggin’ tight). Due to the increased chainline from using the outer position coupled with the bigger diameter wheels, it’s best to gear down.

Most standard triple cranks can be used with the ring in the outer position. To help with chainline, feel free to swap the 2.5mm bottom bracket spacer to the non-drive side if space allows.

What’s going on in the dropouts?

New on this frame is a nifty chain tensioning system. Rather than fiddling with tiny wrenches, you can easily adjust chain tension on both sides with a single 5mm allen wrench (or usually just your hand!) Simply get the dropouts to the desired location and tighten the black knob by hand to lock the tension bolts into place.
