WARNING! Due to the high degree of complexity of the Stumpjumper FSR, proper assembly requires
a high degree of mechanical expertise, skill, training and specialty tools. Therefore, it is essential that
the assembly, maintenance and troubleshooting be performed by an Authorized Specialized Retailer.
WARNING! Many components on the Stumpjumper FSR, including, but not limited to, the rear
suspension and cable guides, are proprietary to the Stumpjumper FSR. Only use originally
supplied components and hardware at all times. Use of other components or hardware will
compromise the integrity and strength of the assembly. Stumpjumper FSR specific components
should only be used on the Stumpjumper FSR and not on other bicycles, even if they fit. Failure to
follow this warning could result in serious injury or death.
WARNING! Never modify your frame or components in any way. Do not sand, drill, file, or remove
parts. Do not install incompatible forks or suspension parts. An improperly modified frame, fork,
or component, can cause you to lose control and fall.
In order to successfully build the Stumpjumper FSR bicycles, it is very important to follow the
order of operations as outlined in this manual. Modifying the order of assembly will result in a
longer build process.
2.1. FORK/HEADSET/STEM
„
The headset uses a 1 1/8” (41.8mm x 30.5 x 8mm, 45x45°) Campagnolo Standard compatible upper bearing
and a 1.5” (52mm x 40 x 7mm, 45x45°) lower 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.
„
Inspect the fork, stem, seatpost and seat tube, to ensure that there are no burrs or sharp edges. Remove any
burrs or sharp edges using fine grit sandpaper.
„
All edges of the stem in contact with the steerer tube should be rounded out to eliminate any stress points.
WARNING! Burrs and sharp edges can damage the carbon and alloy surfaces of the components.
Any deep scratches or gouges in the stem or fork can weaken the components.
2.2. SEATPOST

SEATPOST MINIMUM INSERTION:
To prevent damage to the frame and/or seatpost, it is important
to have a minimum amount of seatpost insertion in the seat tube.
This minimum insertion must meet the following requirements:
„
The seatpost must be inserted into the frame deep enough
so the minimum insertion/maximum extension (min/max)
mark on the seatpost is not visible (fig.1 A).
„
The seatpost must also be inserted into the seat tube deep
enough to meet or exceed the 100mm minimum measured
insertion depth (fig.1 B) required by the frame.
„
If the seatpost and frame minimum insertion requirements
differ from each other, always use the longer minimum
insertion. For example, if the frame requires 100mm, but
the seatpost requires 90mm, then 100mm is the minimum
insertion required.
If the seatpost is at the min/max mark and the seatpost does
not meet or exceed the minimum measured insertion depth of the frame, the seatpost is not inserted deeply enough
into the seat tube and should be lowered until it meets or exceed the frame insertion requirement. This may result in
the saddle being too low. If so, the seatpost must be replaced with a longer seatpost.
WARNING! For general instructions regarding the installation of the seatpost, refer to the
appropriate section in the Owner’s Manual. Riding with an improperly tightened seatpost can
allow the saddle to turn or move and cause you to lose control and fall.
CAUTION: Be sure to not bottom out the seatpost in the frame.
