Summary

The Cannondale Scalpel is a highly innovative cross-country bike that excels in speed, handling, and suspension performance, making it a favorite for competitive riders. Its design allows for efficient pedaling and confident handling on technical descents, though some models may have issues with climbing efficiency and brake performance. The bike's unique features, like the Lefty fork and asymmetric frame, contribute to its standout performance but may pose challenges for upgrades.

Pros
  • Innovative design with efficient pedaling and technical handling

  • Balanced and controlled suspension performance

  • Lightweight and stiff, leading in class for weight and stiffness tests

  • Accommodates two water bottles in the frame’s front triangle for 29er models

Cons
  • Slack seat-tube angle affects climbing efficiency

  • SRAM Level TL brakes may be inadequate for steep descents

  • Idiosyncrasies like the Lefty fork make upgrading challenging

Key Quotes
Cannondale is an incredibly innovative brand and has a long history of creating things in-house that are then followed or disregarded by the rest of the industry.
BIKE Magazine logoBIKE Magazine
The Scalpel SE pedals efficiently, shrugs off technical features bigger than we’d equate with cross country and uses its travel well without being bogged down by it.
BIKE Magazine logoBIKE Magazine
It’s simply letting you know this is one XC bike that’s not meant to be converted to a trail bike.

It’s hard to see how this bike could be improved
BikeRadar logoBikeRadar
Over the last few years, cross-country courses have been changing. The climbs are getting steeper and the descents are getting nastier. There’s no room for error and to win at this game, you need more than just light and stiff, you need capable and stable handling Scalpel-Si is literally built for the world stage

Cannondale Scalpel Si Carbon SE review

Dec 2019 · Mick Kirkman

The Scalpel SE can be sharp, but doesn’t quite cut it in terms of frame shape and rider position

Highs
  • Frame finish, smoothness and pivot hardware detailing are excellent

Lows
  • Suspension isn’t the supplest over small bumps and ripples, which tones down cornering and climbing grip

  • SRAM Guide T brakes are bottom of the Guide range and feel a bit stiff

The Scalpel was an early adopter of a carbon ‘flex stay’ arrangement, at one point had plastic chain stays, super …
