The Cannondale Jekyll 27.5 4 2019 Mountain Bike is entry level enduro bike. With 170mm of travel & agile 27.5” wheels the Jekyll 27.5 works for enduro racing & all mountain riding over the most technical terrain. The Jekyll 27.5 4 comes with a Smrtform aluminium frame & swing arm. The two are connected by the Lock R thru-axle pivot which creates a rock solid connection for added stability. In common with a lot of Cannondale’s other bikes the Jekyll uses Asymmetric Integration (Ai), which basically translates to the back end of the bike being asymmetric. This delivers some of the shortest stays on the market to give more tyre clearance & frame stiffness than even Boost frames can muster. Plus a rear wheel that’s stiffer & stronger thanks to the Ai even-dish build. It all adds up to the kind of agility & traction that has to be ridden to be believed. The Leveraged Single Pivot gives optimal suspension response throughout the stroke & keeps the suspension active under braking, while retaining the stiffness, durability & reliability of a single pivot design. Co-developed with Fox, the Gemini system adds two ride modes (Hustle & Flow) to the Fox shocks. Flip to Hustle to shorten the travel & ramp up the spring rate for a snappier, more responsive feel for pumping through turns, sprints & traction-challenged climbs. Flip back to Flow for full Fox travel when things get rough. The Jekyll 27.5” 4 comes with Fox Float shocks, Shimano SLX gearing & Shimano Deore brakes. This is a really capable bike built with solid equipment that does what it is suppose to without breaking the bank. This bike is perfect for Enduro racers & all mountain riders who prefer the agility of 27.5” wheels. With an aluminium frame & affordable Shimano kit this is a lot of bike for not a lot of money.
