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.

High-pivot mountain bikes are becoming commonplace but the Jekyll's performance is anything but.

Highs
  • Rides light

  • Carries its speed well

  • Lively, nimble enduro machine

  • Adding a coil improves diversity

  • A race bike with everyday riding manners

Lows
  • Stock wheels

  • Stock air shock can have it feeling skittish in loose situations

  • Shock adjustments are hard to reach

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.

Review: 2019 Cannondale Jekyll 29-1

Feb 2019 · Richard Cunningham

The Jekyll 29 marks the final step that Cannondale needed to bring their flagship enduro racer to its potential.

Highs
  • 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

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.
