Endless Coburn Frame — a 4x90 urban inline skate frame for 165mm boots, developed with Si Coburn and proven across street sessions, marathons, group skates, roll-ins, pump tracks, hill bombs, and skate parks. A royalty from every sale supports Si and his skating.

165mm Mount. Standard 165mm raised-heel mounting — recommended for boot sizes 45 and below.

Balanced Rocker. Endless' acclaimed Balanced Rocker geometry delivers the perfect balance of stability and agility the streets demand.
