The version 2.0 of the Riff offers practical updates in features and geometry without going all-in with progressive geometry that almost everyone in chasing. We wanted to keep this frame a hardtail that's great for bike packing and familiar-feeling on long days in the saddle on rolling terrain. There is a slightly steeper seat angle for more efficient climbing and shorter seat tubes to benefit dropper posts.

Tough Broski Sliding Dropouts allow you to run single-speed, geared or even hub gears. Rear hub spacing in updated to Boost 148 . A modified chainstay allows fitting even some double cranks with “plus size” 2.8? wide.
