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 protectionglasses.
Use only spokes of the same length and characteristics
of those being replaced. Use original spare parts
exclusively provided by Wilier Triestina spa.
FRONT HUB
To replace a spoke on disc side is extremely easy, slide
off the spoke from its own seat and insert the new
spoke.To replace spoke on opposite side of disc:
• Remove the contact item (A) (Fig. 1)
• On the same side from which you removed the
contact item, insert a 12mm Allen wrench (M) on the
hub pin and, using a classic 17mm wrench (N),
• unscrew the contact item (B) counterclockwise
(Fig. 2)Unscrew the spoke from the nipples with the
appropriate wrench (Pic. 7).
• Once unscrewed, remove the spoke from its seat.
• Insert the new spoke
• Screw the nipples with the relative washer. To avoid
the torsion effect, hold the spoke.
To solidify the coupling between spoke and nipple, use
a medium thread braking.
• Insert the pin (C) and tighten the spoke (B) with the
17mm wrench (N) at the torque of 15Nm (Fig. 3)
If necessary adjust the hub by working on the ring (H)
(Pic. 2):
• Unlock the grub screw (I) with a allen wrentch 2mm
(L) (Pic. 2).
• Turn the ring in clock sense to drop the sliding, and
in anti-clock sense to rise the sliding
• Lock the grub screw (I).
• Check the sliding of the wheel.
Please check that the hub is correctly tightened and
closed, failure to do so could lead to a serious or fatal
accident.
REAR HUB
To replace a spoke is extremely easy (Pic. 8)
• Unscrew the spoke from the nipples with the
corresponding spanner.
Front wheel

from its own seat.
264,5 mm
• 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)
1100N
• 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.

COMPLETE WHEELS
AIR50KC wheels are designed to fit clincher tyres.
Wilier Triestina spa wheels are designs for use solely
on the road or dedicated cycle track with a smooth
surface. Please ensure that the wheels are not
subject to direct shock from poor road surfaces [i.e.
pot holes].
ATTENTION direct shock to the wheels from poor road
surfaces could lead to wheel failure and resulting
serious or fatal accident. In the event your wheels are
subject to any such shocks from poor road surfaces,
yet do show the signs of any damage we advise you to
immediately have the wheels checked by a qualified
mechanic or other qualified person.
