Grizzly 29+ Mountain Bike

Overview Design Geometry Details Ordering

A remarkably fast and agile 29+ mountain bike in buttery Titanium. The Grizzly 29+ is a skinnier brother of our original Grizzly fat bike. The nimbleness of the bike's geometry compliments the incredible traction, stability, and rollover of its large 29x3" tires. Based on the industry standard Boost spacing / chainline, it shares its brother's incredibly short rear-center and slack head-angle to create a summer hardtail that is fun, fast, and confidence-inspiring.


The Grizzly 29+ frame is designed around a 100mm travel front fork. Its foundation is a wide T47x92 bottom bracket shell that maximizes rear-end stiffness and tire clearance. The drive-side chainstay is dropped via a 6/4 titanium plate and supporting fin; this creates the clearance for large 3.0" tires and chainrings from 28-32 teeth, despite the industry-leading short rear-center.

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.
