>Do not use any tools to install or remove a tubular tire from a carbon rim as they may damage the rim.
Valve Extenders
Rolf Prima carbon wheels come with a valve extender matched to the rim height. Be sure to install
the valve extender before mounting the tire.
Installation procedure:
>
Remove valve core from tube or tire valve using supplied valve core tool
>
Securely install valve core in female threaded end of valve extender
>
Install valve extender into tube or tire valve using supplied valve extender tool. Overtightening

reinserting the valve core
Maintenance
WARNING!
Repair and service of Rolf Prima wheels requires special tools and knowledge, and should
be undertaken only by a qualified service technician at a professional bicycle shop. Repairs,
service, or adjustments performed by an inexperienced person could lead to wheel failure
that may cause a crash resulting in injury.
Care and Cleaning
For general cleaning use soap and water. Do not use high pressure water to clean wheels. High
pressure water can damage the hub bearings.
To remove tubular tire glue use acetone, Goof Off or a similar product. Take care to avoid getting
solvent on the tire, tire/rim bondline or decals. Decals can be damaged by solvents. If this occurs,
replacement decals are available on www.rolfprima.com
Wheel Truing
Wheel truing involves special tools and knowledge and should be performed by a qualified profession-
al wheel builder. Should you suspect your wheels need truing, we recommend that you take them to
your Rolf Prima dealer for evaluation.
Before truing a wheel, it is important to apply oil between the rim and the nipple, and between the spoke and
the nipple. This can be accomplished by dripping oil into the hole where the spoke enters the rim and also
through the hole in the tire well.
Hub Bearing Inspection and Adjustment
Inspection
Over time bearings in your wheel hubs may become worn or may otherwise come out of adjustment.
With the wheel installed on the bicycle, grab the wheel near the brake calipers and gently rock side to
side. If you feel play (light clunking), the bearings may need to be adjusted or possibly replaced. See
www.rolfprima.com for hub adjustment instructions.
For further inspection remove the wheel from your bicycle and remove the Quick Release assembly.
With your forefinger and thumb holding the axle endcap on one side of the wheel, rotate the axle. It
should rotate smoothly. If the bearing turns roughly or noisily, it is time to replace the bearing.
Bearing replacement
Rolf Prima hub systems use a variety of bearings. To determine which bearing you require, refer to the bearing
chart at www.rolfprima.com under service and tech info. Care must be taken during removal and installation
of bearings to prevent damage to the hub shell and bearing. We recommend this procedure be performed by a
qualified service technician. Rolf Prima will not be responsible for damage to the hub or bearing as a result of
improper removal or installation.
Freehub body lubrication and overhaul
Occasionally it may be necessary to service the Freehub Body mechanism. This requires special
knowledge. Rolf Prima recommends this service be performed by a qualified service technician. For
more information, see the Rolf Prima Service Manual at www.rolfprima.com.
WARNING!
Incompatible or improperly installed components can damage your wheelset and/or cause
an accident which may result in injury or death. Make sure your brakes are adjusted and
functioning properly. Make sure your tires are installed and inflated properly. Test the braking
performance of your new wheels in a safe manner.
