Sold out

The Riff is our hardtail frame for 27.5"/650b wheels. (It replaces the B-Side model) While the B-Side showed our tendency of not following the latest trends, the Riff is pretty modern in geometry and features. Tough 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. We even offer a belt-drive ready version. - Tange Prestige heat-treated butted CrMo steel; butted CrMo rear end - Geometry is optimized for 100mm travel 27.5" forks and will handle 120mm forks great too - Disc brakes only (ISO tabs) - Standard or Belt-Drive compatible versions available (split for installing belt is on the seatstay.) - IRD Broski Sliding Dropouts allows geared and single-speed builds with easy wheel removal - S-bend seatstays and chainstays - Rear rack and fender eyelets - CNC-machined 44mm headtube: Will take 1-1/8" steerers with a ZeroStack 44 headset or tapered steerers with a ZS44 upper assembly and external cup (EC44) lower assembly - 31.6mm post size/31.8mm frt. der. size/34.9mm seat collar, 73mm bottom bracket (English threads); 400mm+ post recommended - 135mm spacing for traditional QR hubs.
