27.5" Full Suspension Mountain Bike for kids 9-14. Built for enduro, bike park and trails.

We’re excited to introduce the Rokk 26"/27.5". As with the Rokk 24"/26", we use an adjustable geometry approach to give kids different wheel size options as they grow, but this bike has a decidedly more adult feel to the componentry than any bike we’ve released before. A Rock Shox Pike 160mm fork, Rock Shox Super Deluxe rear shock, SRAM Eagle 12 speed drivetrain and SRAM G2 brakes push the Rokk 26/27.5 into premium adult bike territory.

The 6061-T6 alloy full suspension frame has 160mm of travel provided by a Rock Shox Super Deluxe shock and uses Boost spacing. The frame has a flip chip out back by the SRAM UDH universal derailleur hanger that shortens or lengthens the chainstay and sets the BB height to the appropriate height based on the wheel size. Up front, the Rokk uses a Rock Shox Pike 160mm fork with Boost spacing.

With the bigger frame, we were able to utilize a SRAM Eagle 12-speed drivetrain for the first time. The Rokk uses a SRAM Eagle NX 165mm Dub crankset, SRAM Eagle NX Shifter and SRAM Eagle NX derailleur with 11-52T cassette to give the bike a huge gear range. SRAM G2 4 piston brakes ensure stopping will be as fast as everything else your youngster is doing on this bike.
