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

Highs

  • 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

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

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
