Overview of components
Fork
The RockShox Pike Select is included from the factory. It has a travel distance of 150mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. In short, you should always ensure you have a good fork when purchasing a bike.
Rear Shock
The JEFFSY Pro 29 has a rear shock with a travel of 150mm. The model RockShox Super Deluxe Select + 210 x 55 mm is the one installed in this bike. 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 conclusion, to increase your riding experience, get a bike with a rear shock if possible.
Wheels size
When leaving the production line, the JEFFSY Pro 29 model has 29″ aluminum wheels. 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
For your safety, it is important to have quality breaks on your bike. YT JEFFSY Pro 29 has Hydraulic Disc brakes installed. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, your safety is in good hands.
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.
