WARNING
• Before use, check the wheels to make sure that there are no bent or loose spokes,
dents, scratches or cracks on the rim surface. Do not use the wheel if any of these
problems are found.
• Check that the recommended brake shoe holders have been installed, and that
adjustment is correct. If the brake shoes are adjusted incorrectly, the brake shoe
holder may contact the spokes when the brake is applied, causing noise.
• Do not use in combination with brakes types such as cantilever
brakes in which the brake shoes move in an arc pattern, as the
brake shoes may gradually move closer to the spokes and touch
them as the brake shoes wear.
• Do not use in combination with bottom link-type suspension
forks. With these types of forks, the clearance between the hub axle and the brake
shoes can change due to the operation of the suspension, so that when the brakes
are applied, the brake shoes may touch the spokes.
• If the quick release mechanism is not used correctly, the wheel may come off the
bicycle and serious injury could result. Read the Service Instructions for the quick
release mechanism thoroughly before use.
• Use rim cement to securely affix tubular tires to the rims. If the tires are not fully
secure, they may come off the rims, and serious accidents and injury may result.
• These wheels are designed for riding on paved surfaces. If the wheels are used on
unpaved surfaces, the wheels may become bent or damaged, and accidents may
result.
• Check that the wheels are fastened securely before riding the bicycle. If the wheels
are loose in any way, they may come off the bicycle and serious injury may result.
• Obtain, read and carefully service instructions when installing parts. A loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend that only genuine Shimano replacement parts be used.
• Read these Technical Service Instructions carefully, and keep them in a safe place
for later reference.
CAUTION
• When the brake shoes become worn, the brake shoe holders may interfere with
the spokes and cause frictional noise when the brakes are applied or brake
performance may drop, even if the brake shoes have been installed correctly. If this
occurs, replace the brake shoes as soon as possible.
• Two types of rim are available for use with either tubular tires or clincher tires. Use
whichever type of rim is suitable for the type of tires used, and make sure that the
tires are inflated to the correct pressure.
• The tires should be inflated to a suitable pressure before use.
• If using the rim with clincher tires, use rim tape which can withstand high
pressures, otherwise the tires may suddenly puncture and come off, and severe
injury may result.
CAUTION
• The Shimano R55HC (high performance) brake shoes use an aggressive
compound designed with an emphasis on maximum performance in wet
conditions, however they will cause accelerated rim wear.
Shimano accepts no responsibility for reduced rim life which might occur from
using R55HC brake shoes.
• Use of genuine Shimano spokes, nipples and washers is strongly recommended. If
non-Shimano parts are used, the area where the nipple seats into the hub flange
may become damaged.
• Before use, check that there are no pieces of metal or other foreign objects
sticking to the brake pads. If any such items are present, they may cause damage
to the rim when the brakes are applied.
• The nipples have large diameters and are easy to rotate in order to make it easier
to increase the spoke tension.However, be careful not to overtighten the nipples
when adjusting the spoke tensions. If the nipples are overtightened, damage to the
rim may result.
(We recommended that you ask authorized bicycle dealers to make the
adjustments.)
Note
• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any lubricant to the inside of the hub, otherwise the grease will come
out.
• The hollow on the other side of the valve from the hole is a guide for indicating the
wear of the rim. If this hollow is no longer visible, the rim is at the end of its useful life.
• Use tire tubes with valve lengths of 50 mm or more.
• Special spoke wrenches are available as optional accessories.
• We recommend that you ask authorized bicycle dealers to adjust the spoke tensions
if there is any initial play in the spokes and after the first 1,000 km of riding.
• Spoke protectors (CP-WH71) are also sold separately. Please ask your bicycle dealer
for details.
• For maximum performance we highly recommend Shimano lubricants and
maintenance products.
• Reflectors (manufactured by CATEYE) are also sold separately. Please ask your
bicycle dealer for details.

Installation of the HG sprockets
For each sprocket, the surface
that has the group mark should
face outward and be positioned
so that the wide parts of the
gear projections on each
sprocket and the A part (where
the groove width is wide) of the
freewheel body are aligned.
The groove
is wide at
one place
only.
• For installation of the HG sprockets, use the
special tool (TL-HG16) to tighten the lock ring.
Tightening torque:
30 - 50 N·m {261 - 434 in. lbs.}
• To replace the HG sprockets, use the special
tool (TL-HG16) and
TL-SR20 to remove the lock ring.

Replacement of the freewheel body
After removing the hub axle, remove the freewheel body fixing
bolt (inside the freewheel body), and then replace the freewheel
body.
Note:
Do not attempt to disassemble the freewheel body, because it
may result in a malfunction.
Tightening torque:
35 - 50 N·m {305 - 434 in. lbs.}
