Darwin Frame Set

The Darwin is a versatile, modern, tig welded, Reynolds 725 steel tubed, touring/adventure frameset. Ideal for road or off road riding and can be built in to a variety of different build specifications.

Disc brake compatible and with variable size geometry, this frame also has ample clearance for up to 45C tyres (or 35c with narrow mudguards), in addition to a multitude of bosses to allow for almost every conceivable cage, carrier or cable set up. The Darwin is robust, yet light and provides the comfort you would expect from a quality steel bicycle frame.
