The Cannondale Scalpel-Si HM 1 is one of the fastest and more versatile cross-country bikes on the market. This full-suspension bike is ultra-lightweight, extremely efficient, and very versatile. It is perfect for hitting high speeds on the tough and rugged terrain of a modern cross-country course. The Scalpel-Si strikes the perfect balance of cross-country speed with all-mountain or endurance stability. No sacrifices need to be made in any area aboard this full-suspension machine. With brilliant traction and responsive handling, you will never have to slow down on your Scalpel-Si. Your very best cross-country performance can be brought out with the Scalpel-Si.

The incredibly light frame of the Cannondale Scalpel-Si HM is made of their Hi-Mod carbon fiber. This is the very best version of Cannondale’s BallisTec carbon construction with a mix of high and ultra-high modulus fibers to produce extreme rigidity with as little material as possible. This stiff material gives you the lively and communicative ride feel you need on difficult terrain to keep riders more connected to the trail, letting you push limits with greater control. Charging up climbs and whipping around corners has never been easier than it is with the lightweight frame of the Scalpel-Si.

Modern cross-country geometry keeps the Scalpel-Si rider comfortably in position to hit high speeds on the trail. It features a low flat back to create a more centered weight distribution. Short chainstays are utilized for extra traction and agility. A slack head angle and OutFront steering technology adds to that speed and provides extra stability. Cannondale’s signature Lefty Ocho fork is smooth and precise while cutting down on weight and allowing for extra tire clearance. Cannondale refers to it as “the best XC fork” on the market. It adds to the smooth, fast, and precise ride you already expect from a Scalpel-Si.

Cannondale’s Scalpel-Si HM gives you a good value for a world-class level carbon XC bike. Everything from the innovative Lefty fork to the ultra-light and responsive Hi-Mod carbon frame adds up to the most versatile performance on the trail. This version is equipped with a SRAM Eagle 12-speed groupset for some of the smoothest and highest performing mechanical shifting on the market. It also utilizes SRAM hydraulic disc brakes which provide modulated stopping in all conditions as well as excellent heat dissipation. The Cannondale Scalpel-Si HM 1 leads to some of the best XC performance in the world.
