Summary
The Cannondale Jekyll is a versatile enduro bike praised for its adjustable Gemini suspension system, offering a smooth, bottomless-feeling ride and efficient climbing. Its geometry and handling are optimized for both descents and climbs, though some reviews note a lack of confidence on steep terrains and a perched riding position. The bike's design and spec are generally well-received, with particular highlights on its suspension performance and value.

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
Some may be put off by the Gemini remote

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.

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.

There were plenty of sweet bikes and products on display at Eurobike this year. Walking through the WTB booth we spotted Marco Osborne's Jekyll with

I’ve got to admit…In the past, I was never really a big fan of Cannondale. It started out when I was a kid working at a bike shop that carried them. In my opinion, a great deal of their efforts were different purely for the sake of being different and standing out, not necessarily different because said efforts brought about measureable improvement. The brand has been behind some interesting innovations over the years, but past efforts such as 4-bolt brake rotors were just flat out stupid. But hey…maybe I’m just childish for holding a grudge and being apprehensive. Anyhow, fast forward almost two decades and I

Watch our full video review below: So what’s new? Everything. Cannondale went right back to the fundamentals with this one, leaving a lot of previous development behind. We think it was the right call. Cannondale’s mountain bikes have been crying out for an injection of practicality and rider-first design, and with Jeremiah Boobar (the man …
Great geometry and handling for Enduro riding.
Simple and more user-friendly suspension.
Built to survive the toughest stages.
Suspension isn't supportive if you favour a plush setup with more sag.

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
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
Weight is pretty chunky for a medium-size £5k bike
Limited DIY tuning potential of the linear-feeling rear shock
