4Compound Formulation Powered By Graphene
Four optimised rubbers placed exactly where needed, combining outstanding speed, grip and durability.

An enduro legend with grip in every condition
Trail — The most versatile trail tyre for hardpack to mixed terrain; open knobs shed dirt and mud. The 4Compound puts four rubbers exactly where they are needed — combining speed, grip and durability.
Martello is proven at the top of enduro and downhill. Durable moto-inspired knobs work well on technical terrain in the dry and the wet; progressive siping varies the knob-edge thickness to balance trail feel and grip without losing stability.
