A tough, supple and durable tyre from Hutchinson. The Griffus Racing Lab Tyre is designed for enduro riding and racing.  The tread is designed with a symmetrical centre and side knows, so you have a smoother, more consistent ride, even when gaining speed on the descents. With staggered offset knobs providing a continuous contact patch for consistent and reliable traction while pedalling or braking. A low lug height helps to reduce annoying squiggles and squirms. 

The RR gravity rubber compound features firm structural support overlaid by a softer side density at the surface for cornering traction with more deformation and slower rebound to help soak up big landings and hard hits. 

The Griffus has been a Stif Staff favourite for a while, so it only seemed right for us to start selling a tyre we all love and use.
