Perfect Cross Country Bike

The Good:

The Scalpel Si Carbon 3 combines ultra light weight construction with excellent traction, quick handling, and great downhill stability. The lefty echo fork has an incredibly smooth feel and takes large impacts well due to its progressive damping. Hopping logs with the light front end is a breeze. Climbing, the scalpel always keeps traction, and the lockout is nice for smoother climbs. When descending the bike is very stable and the "out front" geometry Cannondale uses makes it able to quickly zip through obstacles.

The Bad:

Sometimes the scalpel feels just a little too big to fit through trees--but that's more my own riding ability than the bike's fault. The steering takes a bit of getting used to but is actually quite nice once you get the hang of it. The scalpel's greatest weakness is taking tight corners--it has a tendency to slip at lower speeds than it should.

Overall Review:

Overall, the Scalpel Si carbon 3 is the perfect bike for a cross country rider. Its beautiful suspension setup makes it comfortable for riding all day and gives it fantastic traction for climbing and (almost all) cornering, and as soon as you hop on the bike you feel its speed. Any ride is more fun on the scalpel!
