STUMPJUMPER, STUMPJUMPER EVO (STYLE SPECIFIC-SIZING) MY21 SIZING GUIDE

S-Sizing is based on what matters; rider size and style, not inseam. Six sizes, all with similar headtube lengths and standover allow you to choose the size that best suits your individual style. Smaller S-Size numbers are going to be more nimble, thanks to their shorter reach and front-centre measurement, while bigger S-Sizes deliver more stability and a roomier ride.

  • SIZE DOWN FOR MORE MANEUVERABILITY
  • SIZE UP FOR MORE STABILITY
