Intended Use

Features

Insane Traction - Without Compromise - Proprietary Ai offset drivetrain delivers super short chainstays for climb-winning traction and agile handling, without sacrificing mud/tire clearance or limiting you to single ring set-ups.

XC Agility Meets All-Mountain Stability - OutFront Steering Geometry gives you the best of both worlds: slack and stable on hectic descents, yet quick and nimble everywhere else.

The Best XC Fork. Period.Unbelievably smooth and precise, the all-new Lefty Ocho out-corners, out-handles and flat-out rides circles around its XC competition. Its custom extra-long fork offsets (rake) make our OutFront Steering Geometry possible.

Explosive Stiffness Just say no to energy-wasting flex. Scalpel Si is the stiffest XC dually going, thanks to the evenly dished Ai rear wheel, super short chainstays, LockR locking axles and BallisTec Carbon Construction.
