Cannondale Jekyll 4 Main Features
The truth is, you get a lot of bike for the money that you invest into buying Jekyll 4. The rear suspension system makes this bike comfortable and responsive in all conditions and makes it a really capable enduro bike. However, it is not the only high point that it has.
Compared to other Jekyll models, like Jekyll 1 that is full carbon or Jekyll 2 and 3 that are a combination of carbon and alloy, Jekyll 4 has a full alloy frame. This makes this model a bit heavier than its brethren, but it is still quite nimble due to its geometry, which is on par with the more successful enduro bikes. On top of that, the frame can fit a 500ml side-entry cage water bottle and a carbon downtube protector is part of a standard equipment.
Jekyll 4 comes with the pretty much standard trail 1×11 drivetrain with 30T crankset and 11-46T cassette. This offers plenty of range for any harsh uphill that you might encounter. Moreover, the whole drivetrain is moved 6mm outboard so it provides more mud clearance than usual.
The bike is fitted only with the rear derailleur being that it has a 1×11 drivetrain. The derailleur is an SLX, 11-speed which performs perfectly on the trail. It offers subtle and precise shifting even under severe tension.
Tires & Brakes
Both rear and front tire are Maxxis Minion. The front wheel is fitted with a DHF, 2.5”. It’s made of the dual compound for better grip and stronger sidewalls, and it is also folding and tubeless ready. The rear wheel is fitted with a DHR II, 2.4”. It’s slightly slimmer to give more speed on softer tracks, but it will still bite into loose terrain just as well.
Since Jekyll 4 is fitted with a complete SLX groupset, it means that the brakes come from the same family as well. These are hydraulic disc brakes that clutch 180mm rotors both on the front and on the back wheel. On the other hand, the brake levers are Shimano Deore, which is still a reliable and durable choice.
Strongest Point: Suspension
The best feature about Jekyll for is definitely its Gemini rear shock with 130-165mm travel. It gives you two modes that Cannondale names Flow and Hustle. The Flow mode opens all of its 165mm for grinding down very rough trails. On the other hand, the Hustle mode limits the shock to 130mm for a stiffer ride on the uphill. The customization is done at a press of a bike on the handlebar.
As for the fork, Jekyll comes with a Fox 170mm fork that offers three settings. The fork is firm, but at times maybe a bit too firm as it is hard to get the full float out of it if you are on the lighter side. Nonetheless, it doesn’t disappoint on the downhills.
If you are looking for a MTB in a different price range than the Jekyll 4, check out other Cannondale Jekyll models that we’ve prepared for you.
- Cannondale Jekyll 1 – This model is the most advanced and most expensive of the four. It has much better components and a full-carbon frame.
- Cannondale Jekyll 2 – The frame on this model is a combination of carbon and aluminum. It also has SRAM Guide RS hydraulic brakes, compared to Shimano Deore one Jekyll 4
- Cannondale Jekyll 3 – This model is very similar to the Jekyll 4. However, it has much better Shimano SLX brakes.
Cannondale Jekyll 4 Considerations
The bottom point about this bike is that Cannondale has done it again. They have created another capable and high-quality enduro race bike, however, they made it more affordable than the previous models.
This cut in price does not translate into a big cut in performance. The only drawback with this bike is that it is on the heavier side due to its all-aluminum frame. However, with the Gemini rear shock feature that extra weight is not a problem on the uphill.
If you want a bike to set new personal records with but still save some cash, go for the new Cannondale Jekyll 4.
If you do not want to break the bank and go all out on an all-carbon Jekyll 1 but still get a great performance bike that will allow you to tackle any terrain, we say you go for the Jekyll 4. You won’t make a mistake.
