Summary

The Cannondale Jekyll is a highly capable enduro bike praised for its innovative suspension design, including a high pivot and Proportional Response system that adjusts for rider size, ensuring a consistent ride experience. It excels in rough terrain with stable, composed handling and a supple suspension that offers excellent traction and control. While it shines in descending, some reviews note limitations like wheel compatibility and the potential for debris in the shock cavity.

Pros
  • Proportional Response suspension design for size-specific performance

  • High pivot with rearward axle path for improved bump tracking

  • Stable and composed handling in rough terrain

  • Supple suspension with excellent traction and control

  • Innovative frame design with hidden shock placement

Cons
  • Limited to 29″ wheels only

  • Potential for debris to enter the shock cavity

  • Wheelset durability concerns

  • Idler drag noticeable when climbing

  • Shock adjustments hard to reach

Key Quotes
It’s like Cannondale flipped the script with the old frame, taking everything suspension related that was previously up high in the frame, and tucking it down as low as possible
Bikerumor logoBikerumor
The Jekyll is certainly no slouch through the turns where it feels planted and very controlled.
BikeRadar logoBikeRadar
From the get-go the Cannondale Jekyll has proven to be an easy bike to get along with thanks to its centred riding position and balanced weight distribution. The handling is nothing short of exceptional.

[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. As someone that has followed Cannondale’s journey through MTB over the years […]

Cannondale Jekyll 1 – In our big enduro bike comparison test 2022

Dec 2021 · Peter Walker

High pivot rear suspension, “Guidler” and a unique shock position. Without a doubt, the new Cannondale Jekyll is one of the most eccentric-looking bikes in our “Best Enduro Bike of 2022” group test! But how does it stack up against the competition?

Highs
  • Intuitive handling

  • Suspension performance

Lows
  • Background noise and climbing efficiency

  • Shock is hard to access

  • Dirt accumulates between the down tube and plastic cover

  • Spec needs upgrades

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

Size-specific suspension? A high pivot suspension design with 'Guidler' pulley? Big travel? Big wheels? The new Cannondale Jekyll looks good.
