Grolar

The Grolar is our gravel race and adventure bike.  Designed by request from our ambassadors, the Grolar (Grizzly+Polar) is a gravel rolling bear.  Featuring a distinctive head badge on the tapered headtube, and able to run 700cx50 or 650bx2.2 tires, the Grolar is configured to run far and fast in comfort. 

The beautiful titanium frame is designed for rigid gravel forks and can also accept the Lauf Grit gravel suspension fork.  The front triangle is extra large for endurance-sized frame bag capability. Triple bottle mounts on the down tube, and available rack and fender mounts allow multiple bikepacking and touring gear options. The Grolar is 2x compatible and can also run post mount or flat mount rear brake setups (disc brakes only).  It can have sliding dropouts or a fixed thru axle, as you prefer. 

The rear triangle is designed to have a large amount of mud clearance and efficient yet compliant action.  The Grolar is proving to be able to tackle a far wider range of terrain than just gravel roads.  “Pavement, double-track, singletrack, and animal track, this bike will get you there.”  

The Grolar is a design that is proving to be more than the sum of its parts.
