The Endless Coburn Frame is the ultimate 4x90 urban skating platform developed in collaboration with Si Coburn. Over the last year Si has personally tested and proven the versatility of this frame in every scenario imaginable–urban street sessions, marathons, group skates, roll-ins, pump tracks, hill bombs, and skate parks. For those seeking the most responsive and satisfying 4x90 experience ever imagined for 165 boots, the Coburn Frame delivers.

Derived from our Ultra Series, this frame represents the pinnacle of modern skate performance. It features an ultra-stiff structure for maximum power transfer, instantaneous acceleration, and a predictable dynamic response for executing the high speed maneuvers and athletic jumps for which Si Coburn is known. Advanced structural features create a higher level of performance than our Classic and mk2 frames achieve. Our acclaimed Balanced rocker delivers the perfect balance of stability and agility the streets demand.
