Pros and cons
What We Like About Jekyll 4
- 150 mm of travel
- SRAM NX Eagle groupset
- Shimano MT500 hydraulic disc brakes
What We Didn’t?
- Heavier than other Jekyll models
Cannondale has come out with another supreme enduro bicycle for this season, with some great improvements. The Cannondale Jekyll AL 29 4, as its name suggests, can shift its personality by 180 degrees.
At one moment, it can be a composed climber, and a second later it can turn into a downhill and singletrack beast.
Jekyll Al 29 4 also features a dropper post which allows you to transform it with the press of a button. You can then tackle more demanding descents and jumps. The Jekyll 4 is an enduro race bike that has trail written all over it. It will bite into the roughest of terrain and give you an exceptional off-road experience.
Cannondale Jekyll 4 Main Features
The truth is, you get a lot of bike for the money that you invest in 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.
Frame & Drivetrain
Compared to the other three Jekyll models that feature carbon frames, Jekyll 4 is different from an all-aluminum 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 the Asymmetric Integration rear triangle offset means you can fit it with wider tires.
Jekyll 4 comes with an improved SRAM NX Eagle drivetrain with 12 speeds. The old model had 11 speeds, so this Jekyll 4 is faster and more capable than before.
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.
Derailleurs, Tires & Brakes
The bike is fitted only with the rear derailleur being that it has a 1×12 drivetrain. Both the derailleur and the shifter are SRAM NX Eagle, which performs perfectly on the trail. They offer subtle and precise shifting even under severe tension.
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.
Jekyll 4 is fitted with a complete SRAM NX Eagle groupset, but the brakes come from the Shimano family. These are the popular MT500 hydraulic disc brakes with 180mm rotors both on the front and on the back wheel. Brake levers are Shimano MT500 as well, for maximum compatibility.
Strongest Point: Suspension
The best feature about Jekyll 4 is definitely its suspension with 150 mm travel. It gives you more than enough plush and stability no matter the terrain and obstacles.
The rear shock is the RockShox Deluxe Select Plus. It offers great value for money and is known for its durability and opportunities for adjustment.
As for the fork, Jekyll comes with a RockShox Lyrik Select fork that offers 150 mm of travel and a 42 mm offset. 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 an 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 an aluminum-carbon frame.
- Cannondale Jekyll 2 – The frame on this model is also a combination of carbon and aluminum. It is a more expensive model than Jekyll 4.
- Cannondale Jekyll 3 – This model is very similar to Jekyll 4. However, it has a much better Gemini suspension.
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, that is worth every cent you spend on it.
The only drawback of this bike is that it is on the heavier side due to its all-aluminum frame. However, this is not a significant weight difference, so the bike still performs well on the trails.
If you want a bike to set new personal records with but still save some cash, go for the new Cannondale Jekyll 4 AL 29.
If you do not want to break the bank and go all out on a 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.
