Overview of components
Fork
The Hotrock 24 7-Speed Girls comes factory-installed with the SunTour XCT fork. This has a travel range of 50mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. In conclusion, always look for a fork with decent travel when you buy a bike.
Fork material
