A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

Summary

The Cannondale Jekyll is a highly capable enduro bike praised for its innovative suspension design, including a high pivot and Proportional Response system for size-specific performance. It excels in rough terrain with stable, composed handling and efficient pedaling. However, some reviews note limitations like wheel size options and build choices.

Pros
  • Proportional Response suspension design for better performance across sizes

  • High pivot with rearward axle path for improved bump tracking

  • Stable and composed handling in rough terrain

  • Size-specific geometry and suspension kinematics

  • Effective pedaling performance

Cons
  • Limited to 29″ wheels only

  • Only two build options available

  • Stock wheelset could be better

  • Rocks can find their way into the shock cavity

  • Idler drag noticeable when climbing

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 new Jekyll has been toiled over for close to three years now and sports a radically different frame to the old bike.
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.

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

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

Jun 2021 · Zach Overholt

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

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

Lows
  • May be too normal for vanguard riders

  • Fussy shock tune

  • Some may be put off by the Gemini remote
