[R]eviewed // Cannondale Jekyll ‘2’

Feb 2022 · Blake Nielsen

There are a lot of model names that have remained and evolved in different bike brands’ line-ups year after year, but certainly no other single model has delivered as many outrageous and truly ‘left of field’ frame designs over the years as the Cannondale Jekyll. Words // Blake Nielsen  Photos // Matt Staggs This season, as showcased right here, the Jekyll debuts another entirely new frame design concept.

Cannondale Jekyll Review | A striking enduro bike that takes a balanced approach to the high pivot hype

Dec 2021

The Cannondale Jekyll is a 165mm travel enduro bike that has boldly jumped onto the high pivot bandwagon for 2022. Along with its hidden shock, idler wheel and shape-shifting paint job, this is no doubt a thoroughly striking machine. But is different better? Read on for our Cannondale Jekyll review.

Highs
  • Beautifully balanced handling

  • Gobs of traction & high-speed stability

  • Scaled rear centre sizing

  • Reliable shifting & powerful braking

  • Gorgeous iridescent paint job

Lows
  • Dropper post is too short

  • Needs a tougher rear tyre

  • Stock wheels are cheap

  • Rocks can bounce around in the shock cavity

Cannondale Jekyll 1 review

Sep 2021 · Robin Weaver

Cannondale has done a great job with the Jekyll. It’s stable, composed and seriously quick, but a better set of wheels would elevate its performance even further

Highs
  • Great geometry

  • Super stable and composed

  • Solid spec that’s ready to be raced

Lows
  • Wheelset could be better as rims are easy to ding and spokes can lose tension

  • Rocks can find their way into the shock cavity
