The ultimate race bike for the rough and tumble realities of modern XC. It's the lightest, stiffest XC dually on the planet, with radical new XC geometry to own the climbs, rule the descents and decimate the competition.
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 rigid and precise, Lefty out-corners, out-handles and flat-out rides circles around its flexy XC competition. Its custom extra-long fork offsets (rake) make our OutFront Steering Geometry possible.
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.
Ultra Light Weight
System Integrated Cranks, Fork, Frame and Zero Pivot stays all add up to not much…weight. Scalpel-Si is the lightest XC dually on the market.
