Bike wheel accessories

Coverings that wrap around the tyre

The Granite Design Crust covers fit directly over the tyres, with the wheels still mounted on the bike, and catch the mud, dust, and gravel stuck to the tread. They are sold in pairs, one for the front and one for the back, and can be put on in seconds after a ride. Made from nylon, they wash easily after use and fold into their own pouch, small enough to stay permanently in the boot. It's the simplest solution for bringing a mountain bike or gravel bike into an apartment, elevator, or shared space without leaving marks on the floors and walls.

The other wheel parts

The wheels are also available in:

• Road wheels.
• MTB wheels.
• Gravel wheels.
• Rims.
• Hubs.
• Thru axles.

All the wheels can be found on the wheels page.

What size wheel and width of tyre

The Crust covers fit wheels from twenty-four to twenty-nine inches, covering mountain bikes, large children's bikes, gravel bikes, and road bikes, whose rim has the same diameter as a twenty-nine-inch wheel. They can accommodate tyres up to three inches wide, which are the larger MTB tyres. The adjustment is done with Velcro straps in three positions: tighter for a narrow road tyre, looser for a wide tread tyre. Before putting them on, remove most of the mud with a jet or brush, so the cover doesn't become a reservoir for gravel and stays easy to wash.

Transporting and storing your wheels properly

In a car, a bike lying in the boot or disassembled wheels on the back seat quickly dirty the interior: once the covers are in place, the dirt stays trapped in the nylon. For train transport, where the bike often travels suspended by the front wheel in a dedicated space, they prevent marks on hooks and nearby luggage. At home, they protect floors and walls when the bike is hung or propped in an entryway. For long-term storage, keep the tyres inflated, out of direct sunlight and heat sources that can harden the rubber, and wash the covers before folding them away.

Deals

Good deals can also be found in good plans, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped in 24 hours are prepared and sent out within 24 hours. The highlights of the year follow a stable order: Black Friday in late autumn, the end of year festivities, the winter sales, the French Days in spring, followed by summer sales and the back-to-school period.

Frequently asked questions

Do Crust covers protect wheels on a plane?

No, they are cleanliness covers made of nylon, not padded protections. For flights, you need a bike bag or cardboard box with padding around the frame; the Crust covers can be added to contain the dirt.

Can you ride with Crust covers installed?

No, they are only put on while stationary, once the bike is ready to be loaded or stored. Remove them before you set off again: they would strip the tyre of grip and risk getting caught in the frame or brakes.

How do you wash muddy wheel covers?

Let the mud dry, then shake them outside to remove the main part. The nylon can then be rinsed with lukewarm soapy water, and then air-dried before being folded back into its pouch.

Are these covers suitable for an electric bike?

Yes, as long as the wheels measure between twenty-four and twenty-nine inches and the tyres do not exceed three inches in width. They are even valuable on a heavy electric bike that is often brought into a garage or shared space.

Should you deflate your tyres to store your bike in winter?

No, it’s better to keep a normal pressure or suspend the bike, so the tyre does not get flattened in the same spot all the time. Check the pressure each month: a tube slowly loses air, even without a puncture.
