Optimized geometry for both climbing and descending
Lightweight and stiff frame construction
Excellent traction and control on varied terrain
Innovative Asymmetric Integration drivetrain

Drop your heels, let go of the brakes and the way it seems to melt serious drops into nothing is truly phenomenal
The Jekyll is one of the fastest and least tiring bikes of this travel that we’ve ever ridden

The Jekyll stands out on the descents because of its short chainstays and ground-hugging suspension. It stands out on the climbs because of its secret weapon, the Gemini shock, which makes it potentially the best climber in the bunch.

Limited DIY tuning potential of the linear-feeling rear shock
