Product Description

For XC racers, marathon racers and anyone else with dreams of fast-paced XC glory. With 100mm of front and rear wheel travel, modern XC geometry with short chainstays and slacker head angle than traditionally found on XC bikes, a tighter feel for nimble handling at slower speeds, ideal for modern cross country riding and racing. A full carbon fibre frame and the new one-sided carbon Lefty Ocho fork create an incredibly stiff and responsive chassis for ultimate power transfer.

  • Full carbon fibre BallisTec frame with zero-pivot seatstay
  • Fox float Factory DPS shock with remote gives 100mm of rear wheel travel
  • New Lefty Ocho carbon fork gives 100mm of light and responsive travel
  • Carbon HollowGram wheels
  • SRAM XX1 1x12 speed drivetrain to tame the climbs

  • Colour: Jet Black/Brushed Chrome
  • Cannondale Scalpel Si Carbon 1 27.5"/29er is available with 0% APR finance


Built for XXC. The ultimate race bike for the rough and tumble realities of modern XC. This ultralight, super efficient speed machine features unique XC geometry that lets you own the climbs, rule the descents and decimate the competition.
The best climbing, best descending and fastest XC race dually ever made.



  • Insane traction – Without compromise. Proprietary Ai offset drivetrain delivers super short chainstays for climb-winning traction and agile handling, without sacrificing mud/tyre clearance or limiting you to single ring set-ups.
  • XC agility meets all-mountain stability. OutFrount 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.
