Jeffsy 29 CF components
Fork
The fork installed on this bike is the RockShox Pike RCT3 model. The travel on this model is 140mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. To sum it all, when buying a bike, ensure that you look for a fork capable of decent travel.
Rear Shock
From the factory, it comes with the RockShox Monarch RT3 rear shock model, which has a travel of 140mm. Rear shocks give you increased comfort, control, and traction, which is important when cornering or braking. This allows you to ride faster on bumpy roads. In short, if you want smooth rides, get a full-suspension bicycle.
Wheels
The wheels on Jeffsy 29 CF are the 29″ aluminum type. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, these wheels are not ideal for smaller people.
Brakes
Stopping the bike when needed, it’s essential for your safety. This bike has Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, you can ride your bike with confidence.
Dropper post
The YT model is also equipped with a dropper post. A dropper post is a must-have these days if you’re riding anything remotely technical. The main benefit of a dropper post is increased safety while riding. As mentioned above, the lever system allows you to quickly move the saddle out of the way when approaching descents or trail obstacles.
