Overall, both of the Jekyll builds are quite solid value for the price, and weвЂ™re fans of the priorities that Cannondale chose for them.Shopping around for my first road bike, and was wondering if a 52 cm frame would fit. My biggest quibble is that IвЂ™d love to see longer-travel dropper posts, particularly on the larger sizes, but IвЂ™ve been spoiled by 200+ mm posts and swapping in a longer one isnвЂ™t terribly hard or expensive. Overall, these are sensible builds that spend money where it matters the most (suspension, brakes) and save in other areas (drivetrains, wheels) where itвЂ™s a bit less important for a fairly gravity-oriented bike.

Interestingly, the Jekyll only has about 80% anti-squat around the sag point, which is far less than on most modern Trail and Enduro bikes. And according to CannondaleвЂ™s published data, the new Jekyll has essentially zero pedal kickback anywhere in the travel. As weвЂ™ve found in our time on the Session so far (and discussed on Episode 70 of Bikes and Big Ideas), that feels like a good way to balance the benefits of a high-pivot design when it comes to bump absorption, without introducing too much weird behavior when trying to pump the bike through rolling terrain, preload off jumps,etc. Though, as with the new Trek Session, the JekyllвЂ™s axle path isnвЂ™t super aggressively rearward and begins to come back forward around 100 mm into the travel. Typical of a high-pivot bike, the Jekyll has a substantially rearward axle path. This is actually a lot more common than you might think, especially on bikes that vary chainstay length by size (as the Jekyll does - more on that below) and itвЂ™s nice to see Cannondale being somewhat open about it. The curves also indicate slight variations in total travel between frame sizes, with the Small bike falling a little short of the stated 165 mm of rear-wheel travel. The initial leverage ratio varies from about 2.5:1 on the Small to just over 2.8:1 on the XL, and all end up in the vicinity of 2.2:1 to 2.3:1 by bottom out. The leverage curves for the Jekyll are overall fairly linearly progressive, but the Small size in particular has a slight digressive portion early in the travel. It seems fair to assume that taller riders on larger size bikes will generally have a higher center of gravity (though of course, thatвЂ™s a moving target - a rider doesnвЂ™t sit stationary on a bike) but most bikes donвЂ™t tweak their pivot locations to account for that change in height between different size frames. In particular, Cannondale correctly notes that anti-squat and anti-rise are dependent on the height of the center of gravity of the bike / rider system, and in calculating that data, an estimate of where it falls is required. Speaking of sizing, Cannondale makes note that theyвЂ™ve tweaked the suspension kinematics for each size of the frame individually, and they publish graphs showing the changes to the kinematics with each frame size. Cannondale says that the low placement of the rear shock helps lower the center of gravity of the bike, and it also makes room for a water bottle inside the front triangle on all sizes. Cable routing is fully internal, the bottom bracket shell is threaded, and there are additional guards on the downtube to cover the shock, and above the main pivot to shield it from gunk thrown off the rear tire. The lower two bolts from a set of ISCG-05 tabs are included if you want to run a direct mount bashguard, but the Guidler makes the upper bolt (and any chainguide that would mount to it) unnecessary and incompatible.ДЄs youвЂ™d expect for a modern Enduro bike, the Jekyll comes with molded rubber guards on the seatstay and chainstay. Cannondale calls it a вЂњGuidlerвЂќ in reference to the included chain guide on top of the idler pulley (i.e., вЂњguideвЂќ + вЂњidlerвЂќ = вЂњGuidlerвЂќ), and in the case of the Jekyll, itвЂ™s fixed to the main frame. As youвЂ™d expect for a high-pivot bike, thereвЂ™s an idler pulley to guide the chain upward from the chainring before routing it rearwards to the cassette.
