lurcher 29

gravel – adventure – bike packing

The Lurcher is a multipurpose adventure bike. It features 29″ wheels with up to 2.4″ tyre width and plenty of mud clearance. The bike can be fitted with a dropper seat post and can be designed to run a rigid or suspension fork.

A 1×11 drivetrain, fully-housed externally routed shifter cable & brake hose make for a more reliable bike than can be serviced mid-ride (because accidents happen).

The frame is made from Reynolds double-butted steel tubing and makes use of custom 3D printed dropouts and chain stay “yoke” to maximize tyre and chainring clearance without compromising weight or lateral stiffness.
