WARNING! Do not extend the seatpost above the minimum insertion line. Extension
beyond the minimum insertion line can result in failure, causing serious injury or death.
WARNING! Do not pull down on down tube derailleur cables to pre-stress the cables.
This can cause damage to the cable guides.
Your Specialized frame does not require any bottom bracket or head tube pre-
installation preparation. All surfaces are already prepared from the factory, with the
exception of greasing the bottom bracket threads (threaded bottom bracket cups) and
head set cups. For threaded bottom brackets, it is acceptable to chase the bottom bracket
threads if necessary. Do not face bottom bracket cups.
Oversized Bottom Bracket: Please refer to the carbon crank instruction guide
(IG0276 - Crankset - Carbon MTB Crankset) for assembly instructions and compatible
tools. For crank compatibility specifications, please refer to the carbon crank compatibility
guide (CG0308 - Bottom Bracket - Oversized MTB Bottom Bracket). All documents are
available at www.specialized.com.
Specialized Stumpjumper carbon frames use a 1 1/8" (41.8mm x 8mm x 45°)
Campagnolo Standard compatible top and 1.5" (52mm x 7mm x 45°) bottom bearing.
Ensure that replacement bearings are compatible with the Specialized headset
specification. No tools are needed for installation or removal of both bearings. Grease
bearing surfaces before installation.
• Front derailleur: Recommended torque is 44 in-lbf (5.0 N*m).
• Rear derailleur: Recommended torque is 70 in-lbf (7.9 N*m). Ensure that the threads
are clean prior to installation.
• Seat collar: Recommended torque is 45 in-lbf (5.1 N*m).
• Water Bottle Cage: Recommended torque is 35 in-lbf (4.0 N*m).
WARNING! Great care should be taken to not damage carbon fiber or composite
materials, including the frame and any carbon fiber or composite components. Any
damage may result in a loss of structural integrity, which may result in a catastrophic
failure. This damage may or may not be visible in inspection. Before each ride, and
after any crash, you should carefully inspect your bicycle for any dents, fraying,
gouging, scratches through the paint, chipping bending, or any other signs of
damage. Do not ride if your bicycle shows any of these signs. After any crash, and
before you ride any further, take your bicycle to a Specialized Authorized Dealer for
a complete inspection.
