OVERVIEW

The terrain that surrounds us is nearly static and unchanging.  Bike technology, by comparison, moves at light speed every single day.

With mountain bike standards shifting slowly towards more tire clearance and wider gearing ranges, the Tunnel steps up to the plate with full Boost compatibility.

Experience the new innovation behind Boost technology on familiar terrains.  Set yourself free.
