65-degree head tube angle, steep seat tube angle and short 420mm chainstays give you the confidence and control on the most demanding terrain.
Only Asymmetric Integration (Ai) can deliver short stiff stays with no downside. Incredible agility and traction plus a stiffer, stronger rear wheel and big tire mud clearance - that’s the Ai magic. Zero compromise is the game and Asymmetric Integration (Ai) is the name. Ai delivers some of the shortest stays on the trail and has way more tire clearance and frame stiffness than any traditional boost design can muster.
Combined with a rear wheel that’s stiffer and stronger thanks to the Ai even-dish build, the all new Jekyll has the kind of agility and traction that has to be ridden to be believed. It’s not magic, it’s asymmetric.
Optimize your ride on-the-fly with the Jekyll’s new Fox Gemini shock – Hustle Mode for the sprints and the climbs and Flow Mode for pure unaltered Fox downhill performance.
Co-developed with Fox, the Gemini system adds two ride modes (Hustle & Flow) to the killer performance of Fox shocks. Flip to Hustle to shorten the travel and ramp up the spring rate for a snappier, more responsive feel for pumping through turns, sprints and traction-challenged climbs. Flip back to Flow for full Fox travel when things get rough.
