The 403 uses a REVO Shift so small hands can easily exploit the huge range of gears 11-40T. We've broken the mould with our kids bikes. By putting 26" wheels on a kids MTB we've given a boost in performance similar to an adult switching to a 650b/27.5" Trail Hardtail. More confidence, more control & easier riding. The 403 also comes with Whyte's own Get-a-Grip seat post clamping system. This easy to use clamp allows the post to be raised or lowered on the trail, even with small cold hands.• SR Suntour XCM suspension fork with aluminium steerer tube to save weight• Shimano 1 X 8spd drivetrain• Lightweight aluminium frame with internal cable routing• Chainstay Guide for Tension
