Overview of components
Fork
The Men’s Stumpjumper ST Expert 29 comes factory-installed with the RockShox Pike RC fork. This has a travel range of 130mm. Bike forks absorb the shocks and give you a smooth and pleasant ride. To sum it all, when buying a bike, ensure that you look for a fork capable of decent travel.
Rear Shock
The shock that’s installed on this bike is RockShox Deluxe RT3, with a travel distance of 120mm. 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. To sum up, get a full-suspension bike if you want the smoothest rides.
Wheels size
When leaving the production line, the Men’s Stumpjumper ST Expert 29 model has 29″ carbon 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
Stopping the bike when needed, it’s essential for your safety. This bike has Hydraulic Disc brakes. Hydraulic disc brakes are perfect for mountain biking, road cycling, and commuting. To sum up, these are ideal for anyone.
Sizes
Men’s Stumpjumper ST Expert 29 comes in 4 sizes, that range from 158 cm – 199 cm (5.18 ft – 6.53 ft). In conclusion, finding one for you shouldn’t be a problem.
Dropper post
Every bike should have a dropper post, and this one does. 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.
