Appendix D
: Fastener Torque Specifications
Correct tightening torque of threaded fasteners is very important to your safety.
Always tighten fasteners to the correct torque.
In case of a conflict between
the instructions in this manual and information provided by a component
manufacturer, consult with your dealer or the manufacturer’s customer service
representative for clarification.
Bolts that are too tight can stretch and deform.
Bolts that are too loose can move and fatigue. Either mistake can lead to a
sudden failure of the bolt.
Always use a correctly calibrated torque wrench to tighten critical fasteners on
your bike. Carefully follow the torque wrench manufacturer’s instructions on the
correct way to set and use the torque wrench for accurate results.

Torque Specifications:
WARNING: Failure to follow the torque specifications in this
installation guide will void your warranty, but most importantly may
result in damage to the frame that may not be visible. If the frame is
damaged, this can result in loss of structural integrity, which may result in
serious personal injury or death.
A) BOTTOM BRACKET
Refer to your bottom bracket owner’s manual prior to installation. Ensure that the
Bottom Bracket shell threads are clean and greased prior to installation. Do not
exceed maximum torque of 50Nm (435in-lb).
Felt Carbon Fiber bicycle frames are precision machined to accept a 68mm,
English threaded Bottom Bracket, so there is no need to machine them
again. With the exception of greasing the bottom bracket threads, your Felt
frame does not require any Bottom Bracket pre-install preparation. Should
damage occur to the treads in the bottom bracket shell, it is acceptable
to chase the bottom bracket threads. Do not face bottom bracket shell or
otherwise attempt to modify the surfaces of the bottom bracket.
B) SEAT POST
Refer to your seat post owner’s manual prior to installation. Felt road frames
have a 27.2mm seat post diameter and require that the seat post have a toler-
ance of 27.12mm to 27.20mm. The seat collar inner diameter is
30.6mm.
Felt Carbon Fiber bicycle frames are precision machined at the seat tube
post interface so there is no need to machine them again. Recommended
torque is 60in-lb (7m). Do not exceed maximum torque of 75in-lb (8.4Nm).
Exceeding this limit can result in damage to the seat post.
WARNING: Do not extend seat post above the minimum insertion line.
Extension beyond the minimum insertion line can result in failure,
causing serious injury or death.
C) HEADSET INSTALLATION / REMOVAL
Use only Cane-Creek IS2-type Integrated Headsets.
Felt Carbon Fiber bicycle frames are precision machined at the head tube, BB,
and the seat tube post interfaces so there is no need to machine them again. Do
not face, ream, or otherwise attempt to modify the surfaces of the head tube.
D) FRONT DERAILLEUR
Recommended torque for the front derailleur is 5Nm (44in-lb). Do not exceed
maximum torque of 7Nm (60 in-lb).
E) REAR DERAILLEUR
Ensure that the threads are clean prior to installation. Recommended torque for
the rear derailleur is 8Nm (70in-lb). Do not exceed maximum torque of 10Nm
(87in-lb).
F) BRAKES
Recommended torque for road brake calipers is 8Nm (70in-lb). Do not exceed
maximum torque of 10Nm (87in-lb).
G) WATER BOTTLE CAGE
Recommended torque for the water bottle cage bolts is 3.9Nm (35in-lb). Do not
exceed maximum torque of 4.5Nm (40in-lb).
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 struc-
tural 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 dam-
age. Do not ride if your bicycle shows any of these signs. After any crash,
and before you ride any further, take your bicycle to an authorized Felt
retailer for a complete inspection.
