Tested: Cannondale Jekyll 2 | $6,000

Aug 2018

The Jekyll stands out on the descents because of its short chainstays and ground-hugging suspension. It stands out on the climbs because of its secret weapon, the Gemini shock, which makes it potentially the best climber in the bunch.

Cannondale Jekyll 2.0 Review : Jekyll Or Hyde, You Decide!

Apr 2018 · Thomas Corfield

We first featured the new Cannondale Jekyll back in April ‘17 and described it as a real, ‘Marmite’ bike with a split personality you either loved or loathed.

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 …
