If you notice any signs of corrosion or cracking on the frame or any component, the affected item must be replaced.

    4.2. FRAME/BIKE CUSTOMIZATION: Stumpjumper FSR frames are available in two frame types (29” or 27.5”), each of which is available in two stock configurations (SJ ST and SJ), with different wheel/tire, shock, shock extension and/or fork options. Each of these variables will affect the bottom bracket height and head angle of the frame, as well as the general ride characteristics of the bike.

  • Page 9: Tools Required

    WARNING! While the 29 frame is generally compatible with tires up to 27.5 x 3.0 or 29 x 2.6 and the 27.5 frame with tires up to 27.5 x 3.0, tire dimensions can vary depending on the manufacturer, and not all forks are designed to accept a larger tire. Always check with the fork manufacturer regarding required clearances.
