Rise Grizzly 29 Hardtail Mountain Bike

Overview Design Geometry Details Ordering

A remarkably fast and agile 29er hardtail mountain bike in buttery Titanium. The Grizzly 29 is a skinnier brother of our Grizzly fat bike. Based on the industry standard Boost spacing / chainline, it shares its brother's modern trail-oriented geometry to create a summer hardtail that is fun, fast, and confidence-inspiring.

The latest generation of Grizzly 29 makes judicious use of advanced additive manufacturing (3D-printing) technology - head tube, dropouts, and chainstay yoke are made from 6Al/4V Titanium by Selective Laser Melting - resulting in a frame that is a unique combination of cutting edge fabrication, and classic looks. (Note: main photos show prior generation bike)


The Grizzly 29 frame is designed around a 120mm travel front fork. Its foundation is a wide T47x92 bottom bracket shell that maximizes rear-end stiffness and tire clearance. The drive-side chainstay uses a 3D printed yoke to maximize tire clearance, and is compatible with up to a 32 tooth chainring.

Like its fatter brother, the Grizzly 29's main triangle is made from oversized and shaped 3/2.5 titanium to create a ride that is both lively and precise.

The latest generation of bike uses seamlessly integrated, 3D printed dropouts which incorporate a post mount that protects the rear brake, and creates a stiff platform by triangulating it between the stays. The dropouts use the Universal Derailleur Hanger (UDH), are Sram Transmission (direct-mount rear derailleur) compatible, and utilize a conical, Syntace-style head for maximum stiffness and precision.
