Feb 2019 · Richard Cunningham

The Jekyll 29 marks the final step that Cannondale needed to bring their flagship enduro racer to its potential.

  • Ready-for-anything build

  • Great flow going up or down

Review: All of a sudden it just appeared out of nowhere: the Cannondale Jekyll 29! We quickly put one to the test on the trails.

Tested: Cannondale Jekyll 29 3

The 29-inch Jekyll promised to offer the support and stability we wanted more of in its small-wheeled sibling. And it did, but in a decidedly conservative, trail-oriented package.

Tested: Cannondale Jekyll 2

Sep 2017

Highs
  • Great geometry and handling for Enduro riding.

  • Simple and more user-friendly suspension.

  • Built to survive the toughest stages.

Lows
  • Suspension isn't supportive if you favour a plush setup with more sag.

Cannondale Jekyll 2 review

Aug 2017 · Guy Kesteven

Excellent geometry and kit plus unique shock create a crazy-fast enduro ripper. Buy if you want sorted shape, pert/plush performance with metal wheel toughness

Highs
  • Gemini shock system allows instant switching between super-plush speed or a tighter, more dynamic ride

  • Long-stretch/slack-head geometry, wide/short cockpit and XL front tyre create a massively confident front end

  • Excellent tough trail spec

Lows
  • Weight is pretty chunky for a medium-size £5k bike

  • Limited DIY tuning potential of the linear-feeling rear shock

Review: The 2018 Cannondale Jekyll switches from a well-mannered climber to a downhill bruiser

Aug 2017 · Steve Fisher

As the name suggests, the Cannondale Jekyll has two distinct personalities. Most of that is the result of the Gemini-equipped Fox rear shock which adjusts its travel from 130-165mm and changes its spring rate with the press of a button. In climb mode the bike’s rear end rides high, leaning you into a solid position …
