Wheel/Rim Maintenance

Boyd Cycling wheels are hand built in the US by a very experienced wheel builder. Every wheel has been checked thoroughly for trueness and tension and spoke freeze is applied after the build to keep the wheels in true. Occasionally wheels can go through a normal break in period where a spoke or two may need to be tensioned. This is perfectly normal and should be performed by a professional mechanic.

The carbon braking surface is very strong and durable but certain precautions should be taken to ensure that your wheels will last you many years. Our Onyx brake pads are supplied with all carbon wheels and are recommended for use. The Swissstop Black Price pad is also acceptable to use, however the yellow pads from Swissstop should never be used on any carbon wheel.
You should never use the same brake pads on carbon wheels that have been used with an aluminum braking surface. The brake pads can pick up tiny chards of aluminum that can be damaging to carbon rims.

If your brakes are squealing with the carbon rims, you will need to adjust the toe-in of the brake pads. An easy way to do this is to fold a business card in half and place it behind the rear portion of the brake pad. Squeeze the brakes against the rim and tighten. Now the front half of the brake pad will be angled towards the rim and your wheels won’t be screaming at you.

Hub Maintenance

Boyd Cycling hubs are designed to be lightweight, strong, and very easily serviceable.

The Rouleur wheelset uses a different rear hub than all the rest of our wheels. It has 4 bearings in the rear hub (two in the freehub body, two in the hub shell). The Rouleur rear hub features 2X size 6802 and 2X 6902 bearings.

Occasionally dirt particles can enter the rear hub, especially if you have been riding in the rain. If you ever feel your freehub body slip, this is due to one of the pawls in the back getting stuck. Simple loosen up the rear hub with two 5mm allen wrenches, and the non drive side end cap will come off. By pressing on the axle, the freehub body will dislodge from the hub. Here you can clean the pawls and add some lubrication to them (use a low viscosity oil based lube). When reassembling the rear hub on the Rouleur, simply tighten down the end cap by sticking two 5mm alen keys in the end caps and tighten down really good.

The rear hub featured on the rest of the wheels features a pre-load system to tighten the hub. To tighten the hub with a pre-load put a 5mm alen key in the drive side end cap. Thread the pre-load into place until it’s finger tight. If your pre-load has a 2.5mm allen bolt you can now tighten that in place to lock the pre-load into place. Put the non drive side end cap in place and lock it into place against the pre-load by using a 5mm allen wrench in each end cap.

For these rear hubs (found on every wheel except the Rouleur), there are 3X 6802 bearings (both freehub body bearings and the hub shell NDS bearing) and 1X 6902 bearing (the hub shell drive side bearing).

If you have the 2013 or 2014 model rear hub (shown here) then the hub will take 2X 6802 and 2X 6902 bearings.

Front hubs use two 6900 size bearings. To access the bearings simply put two 5mm aen keys into the end caps. Loosen them and one end cap will come undone. You can now put a 6mm aen key inside the axle. There is a 6mm slot inside the axle that you can use against the remaining end cap to loosen this. To tighten the end caps, just reverse this procedure.

Warnings

For carbon clincher rims, never inflate to more than 130PSI. Also, never leave fully inflated tires inside your car on a hot summer day. The increase in temperature can cause the PSI to skyrocket and damage the sidewall of the rims. Releasing a small amount of pressure from the tires will be fine.

Mild cleaners only should be used in the cleaning of the carbon rims. Rubbing alcohol is a great choice for keeping your wheels clean. Harsh cleaners, such as acetone, can damage the decals on the rims.

Rim strips should always be used with the wheels before putting the tubes and tires on the wheels. If you do not use rim strips, your tubes will flat very quickly! Rim strips are included with all clincher rims.

Never use any sharp objects to mount the tires on your wheels! Objects such as screwdrivers, wrenches, scissors, etc can damage the carbon rim and will void your warranty. Always use plastic tire levers for mounting tires, and be patient. . putting brand new tires on carbon rims can be a difficult process.

Other Warnings

You may notice an increase in speed with these new wheels. This is perfectly normal and should be anticipated. Don’t be surprised if your riding partners are a bit upset with you at first and present you with humorous excuses as to why they couldn’t keep up. PR’s have also been known to occur within weeks of receiving your new wheels.
