Cannondale Jekyll 29-1 Action Photos by Trevor Lyden Definitely more Hyde than Jekyll, Cannondale’s newest iteration of their flagship enduro machine has been graciously updated for the modern trail rider. Cannondale has been at the forefront of shape shifting technology for many years, and the

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
Big wheel roll-over without big wheel sluggishness
May be too normal for vanguard riders
Fussy shock tune

Long-stretch/slack-head geometry, wide/short cockpit and XL front tyre create a massively confident front end
Excellent tough trail spec
Weight is pretty chunky for a medium-size £5k bike
Limited DIY tuning potential of the linear-feeling rear shock

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 …
