Steel 650B

The Steel 650B from Torus Bicycles is a modern classic. A fusion of fillet-brazed butted steel yields a light weight, but durable, frame with that unmistakable steel ride quality.

The Steel 650B was designed in the UK as a versatile cross country trail bike. Double-butted 520 cromoly is used throughout, to help keep the weight down. The sliding dropouts allows the bike to be set up a single speed or geared.  It can be run rigid or with suspension forks - the choice is yours. But with 27.5 inch wheels and classic steel tubing, a smooth ride is guaranteed.
