Summary

Cannondale Topstone Neo Carbon Lefty LE in review

Sep 2021 · Philipp Schwab

With the Cannondale Topstone Neo Carbon Lefty LE, an E-gravel bike seems to have smuggled itself into the ranks of the test and approaches urban mobility from a more leisure-oriented perspective.

Highs
  • Innovative in its segment and beyond

  • High-tech and high-spec

  • Off-road capabilities

  • Lots of fun for tech-fans with riding experience

  • Comparatively high level of comfort

  • Connectivity of drivetrain, sensor and Nyon display

Lows
  • Very limited luggage carrying options

  • Not intuitive due to road bars

  • Narrow range of applications

  • Limited everyday practicality without mudguards, stand or front light

Video review: Cannondale's full suspension gravel ebike, the Topstone NEO Lefty - CyclingTips
