If you have any doubt whatsoever your service-repair ability,
please take your bicycle to a qualified repair shop.
Before any maintenance operations on your wheels, always wear
gloves and protection glasses.
Use only spokes and nipples of the same length and characteri-
stics of those to be replaced.
Use original spare parts exclusively provided by Fac di Michelin.
To replace a spoke on the 977 is extremely easy in both cases, front
as well as rear wheels.
• Unscrew the spoke from the nipples with the corresponding
spanner.
• Once it has been unscrewed, slide off the spoke from its own seat.
• Insert the new spoke.
• Screw nipple with washer.
Draw the spoke to be used for the replacement in the thread-locker
you chose to improve sealing.
To ensure the correct spoke tension please follow the indications
below:
• Correct spoke tension for front wheel (disc side) 1000N
• Correct spoke tension for rear wheel, free wheel side 1300N
To evaluate the correct wheel tension, please use a professional
spoke tension gauge, we do not recommend that spoke tension is
estimated manually; please refer to a professional cycle mechanic
if you do not own a professional spoke tension gauge. The correct
spoke tension is essential to ensure a ridged and durable wheelset.
AttentIon in correct spoke tension, too high or too low, could lead
to wheel failure and resulting serious or fatal accident.
