Gary Fisher bicycle frames are constructed from a variety of
high performance materials. For safe operation, and long life,
take care of your bike frame by following these instructions.
Inspection
Before every ride carefully inspect your frameset (frame
and fork) for signs of fatigue. Scratches, cracks, dents,
deformation, or discoloration are signs of stress-caused fatigue.
If any part shows signs of damage or fatigue, replace the part
before riding the bicycle.
Frame information- all frames
Gary Fisher framesets use three sizes of seat lugs designed to
accept seat posts with 27.12 to 27.20 mm, 29.12 to 29.2 mm,
or 31.45 to 31.60 mm outer diameter. According to the specifi-
cations for your frame, the seatpost should be measured for
conformity to this tolerance prior to installation.
For aluminum or steel frames, lubricate the seatpost to
prevent seizing in the frame.
The aluminum or OCLV carbon fiber composite parts of your
bicycle, both frame tubes and parts like rockers or dropouts,
are not as ductile as steel. Attempting to make adjustments to
an aluminum or OCLV part by bending or twisting it poses a
risk of breaking it. Readjustment of aluminum or OCLV frame
alignment is not recommended.
Tolerances for press fits and thread fits are critical. Pressing
a part which is too large, or misaligned, may break the frame
or part. Over-torquing a threaded fastener may ruin the
threads or break the part. Be sure bottom bracket and rear
derailleur threads are clean and well greased before insertion.
Start threads by hand, not with a wrench. Torque specifications
for bottom bracket cup threads is 430-610 lb•in (48.6-68.9
Nm). Torque specifications for rear derailleur threads is 70-85
lb•in (7.9-9.6 Nm).
When cleaning frame parts, do not use solvents or harsh
CARE OF YOUR FRAME OR FORK
WARNING
Never modify your frameset or parts in any way, including
sanding, drilling, filing, removing redundant retention devices,
installing incompatible forks, or by any other method. An
improperly modified frame, fork, or component can cause you
to lose control and fall.
