The Release 4C features the same bottomless-feeling rear suspension and deft handling as our aluminum Release models, but with an even lighter, stiffer chassis built from carbon fiber. It starts with our Level Link suspension system, which isolates chain forces from trail inputs. This means 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.
- Level Link design equals 130mm of efficient yet supple rear suspension
- Light and stiff carbon frame with Boost 148x12mm Maxle dropout
- KS LEV Si dropper post (w/ Southpaw remote lever) adds maneuverability on descents
- Fox 34 Performance Float and Fox Float DPS EVOL LV rear shock provide supple suspension travel (150/130mm, front and rear)
- Plenty of gearing to tackle steep climbs, thanks to SRAM NX Eagle 11-50T, single-ring drivetrain
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
