All new and redesigned Scalpel-Si. Built for XC.
Short is effective
The Scalpel-Si and its asymmetrically shifted Ai drive brings an ultra-short rear structure, and thus maximum traction and a lively driving performance without compromise. The Ai package also includes a wide tire clearance, full 2x compatibility and a stiffer and stronger rear wheel.
Low weight
With Ballistec carbon construction and a System Integration approach, the Scalpel Si is the world's lightest and stiffest full-suspension XC bike.
No redundant pins
Transversely stiffer and lighter than a traditional rear structure with studs. Flexible Zero-Pivot rear struts are a hallmark of the Scalpel.
New modern geometry
Composed and stable for hard descents and at the same time still fast and nimble on technical descents. The Scalpel-Si's new modern geometry brings you the best of both.
Pin instead of pins
The expandable fixed axis of the LOCKR system creates the strongest possible connection. Stiffer and lighter. No need for special tools.
Full control over cables
Small things make the whole. New replaceable cable routing inserts allow you to use the configuration you need. It also anchors everything in place, so your perfect cable loops always stay perfect.
