• All our hubs are built with annular bearings (see table “Bearings of CORIMA hubs”, chapter 12).
• Periodically check the wheels’ centering.
• In case of a fall or a violent impact, you must have your wheel checked by our technicians.
Any violent impact can lead to damages which are often repairable by our composites after-sales department, but such
repairs will be billed to you.
• To clean your wheel, don’t use any high-pressure water device, especially to clean the hub in which pressurized water
may penetrate and damage the bearings or components of your cassette body for the rear wheel.
Use a cloth to dry your wheel.
• Times and kilometer readings are given for guidelines and can change significantly according to usage conditions and
the intensity of your activity (example: competition, rain, salted roads, etc…).
• Regularly check the wearing status of your wheels and rims. You must not ride your wheels if you notice cracks on the
rim and/or the hub, if the wheel is broken, damaged or if the braking surface is irregular or worn.
• Regarding the wearing status of the rims, have a check performed each season in our workshops to ensure the best
possible control. CORIMA will check the wearing status and will inform you of the reliability of your rims.
FOR TUBULAR WHEELS, 650C (26’’) or 700C (28’’).
Don’t mount tubular tires with too narrow sections because they may cause damages to your rim. For comfort and
performance, we recommend the setting of 20 mm tubulars for time-trials and 21 mm tubulars for road racing, 650C (26’’)
or 700C (28’’).
There is no maximum air pressure for tubular wheels except the one recommended by the manufacturer of the tubular tire you’re
going to set on your wheels.
E-2 | HANDBIKE WHEELS
HBB (tubular) and HBP (clincher) HANDBIKE WHEELS
• After using your wheels for the first time, check the wheels’ centering.
• After each ride, check the condition of your tubular or clincher tires, as well as the tire pressure (maximum authorized air
pressure for clincher wheels : 8 bars -120psi).
• Don’t mount tubular or clincher tires with too narrow sections because they may cause damages to your rim.
• Every 2000-3000 km, or more frequently in bad weather, lubricate your hub axle and grease the pawls of the cassette
body and the notched crown (see chapter7). High speed grease for precision bearings and plain bearings (grease such as
Kluber Isoflex Super LDS18 type) to prevent from any type of oxidation, aging and corrosion. Don’t use oil which would dilute
the grease of the ball bearings. When setting the external blocking screws, use light locknut glue, the tightening torque must
be
5Nm.
• All our hubs are built with annular bearings (see table “Bearings of CORIMA hubs”, chapter 12).
• Periodically check spokes’ tension and wheels’ centering.
Spoke tension is adjusted from inside the rim (spoke nipple in reversed position) using the specific spoke wrench delivered
with your wheel. Warning! Spoke tension must not exceed the tension applied during mounting in the factory to avoid
irremediably damaging your rim. (see chart in chapter 14, “Adjusting the spoke tension and the centering of the wheels”).
• Only use specific CORIMA brake pads for braking on carbon rims.
• In case of a fall or a violent impact, you must have your wheel checked by our technicians.
Any violent impact can lead to damages which are often repairable by our composites after-sales department, but such
repairs will be billed to you.
• To clean your wheel, don’t use any high-pressure water device, especially to clean the hub in which pressurized water may
penetrate and damage the bearings or components of your cassette body for the rear wheel.
