Description
The Release 4C features the same bottomless-feeling rear suspension and deft handling as Diamondback's aluminum Release models, but with an even lighter, stiffer chassis built from carbon fiber. It starts with a Level Link suspension system, which isolates chain forces from trail inputs, meaning the suspension doesn’t bob when you stomp on the pedals, yet becomes extremely plush on technical descents.
For smooth bump-eating performance, the Release 4C is equipped with a Fox Float DPS EVOL LV rear shock and a 150mm travel Fox 34 Performance Float fork. SRAM’s NX Eagle 12-speed single-ring drivetrain provides consistent shifting and, thanks to its 50-tooth granny gear, makes short work of pesky climbs. SRAM Guide R brakes keep you slicing through the most technical lines all day long.
