Cannondale Jekyll 2 review

Jun 2022 · Robin Weaver

Composed, capable and a lot of fun to ride. Better wheels would make the high price tag easier to handle, though

Highs
  • Great geometry

  • Balanced suspension

  • Composed when it counts

Lows
  • Wheels could be better for the money

  • Spec works well enough but certainly isn’t flashy considering the price

[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.

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
