The Riff is Soma's hardtail frame for 27.5"/650b wheels. (It replaces the B-Side model) While the Soma B-Side showed Soma''s tendency of not following the latest trends, the Riff is pretty modern in geometry and features. Tough IRD Broski Sliding Dropouts allow you to go single-speed or geared or even run hub gears. Also new is internal seat tube dropper post routing. A modified chainstay allows fitting even some double cranks with "plus size" 2.8" wide tires without needing to invest in Boost parts.
