Details
The Rift Zone JF 24 is for the ambitious kid looking to keep up with the adults and push the boundaries of the local bike park on a ride just as capable as its full size counterpart.
The Rift Zone Jr is easily upgradable to 26” wheels and longer cranks as your little ripper grows. 26” wheels and longer cranks not included, but your local Marin dealer can source the parts.
Real singletrack riding
Keeping up with the parents
Fun!
