Cannondale’s Jekyll 2 rolls on a fast, light, and tough BallisTec carbon frame that shrugs off enduro brutality and arrives at the bottom begging to do it again and again. And you will, too, with 165mm of Fox Float X Elite EVOL-guided travel in back and 170mm more up front, courtesy of Fox’s stiff, enduro-loving Float 36 fork. Together, they make easy work of gnarly descents where the only break you get is the climb back up. Since we’re talking about climbing, the Jekyll is no slouch in the uphill department, either, with a switch-on-the-fly rear suspension that offers Hustle Mode for tenacious efficiency. Put the power to the 12-speed SRAM X01 Eagle drivetrain via Descendant carbon crankset, and you’ll gain elevation as fast as you drop the competition. And, for all-mountain dominance, you won’t find better rubber than the Jekyll’s Maxxis Minions, wrapped around 29mm WTB Frequency Team rims that spin up fast and take enduro punishment like a masochist. SRAM’s sweet Guide RS brakes modulate beautifully to keep you on course, even when that course can only be described as “sketchy.” So, jump on, slam the RaceFace Turbine dropper post, and flow this trail beast straight to victory.

Cannondale carbon old timer

More Fun Than Last Bike, Dyad Is Way Adjustable, Slack Angle Handles Great, Lefty Does The Job
Coffee Grinder Chainguide, Cable Disaster, Seat Post Breaks, Constantly Creaking
Best Uses:
Can Handle Any Terrain
Trial riding but have brought it to Mammoth and Stens Pass with no complaints. Has helped me handle everything I've risked and mostly everything I didn't mean to. Lefty has more travel than I expect every time. When it's been tuned up and tightened it is extremely stiff. If you don't keep up on maintainence it can start to creak on you pretty bad. Cables are a disaster, cannondale? never again. It's beautiful and I love it,.

Best bike I've ever ridden

Balanced Suspension, Plush Feel, Handles Well, Great Components, Lightweight, Durable
Best Uses:
Mountain Biking
I've ridden Santacruz to Giant and no bike has a better fit, feel or plushness. The new Fox DYAD shock is amazing. The shifting has no glithes at all with the SRAM X-9. Buy this bike if your serious about being the best you can be.
