Warning
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
characteristics of those to be replaced.
Use original spare parts exclusively provided by Fac di
Michelin.
To replace a spoke on the 988 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.
