![]() It used to be dreadful with little consistency, but manufacturers have gradually improved things. In addition, the rims have weaker braking performance than aluminium rims, especially in wet conditions.”Īdmittedly, braking on carbon rims has got a lot better since the early days. Carbon brake pads usually wear out faster than conventional brake pads. “We recommend brake pads made by or recommended by, the wheel manufacturer. “Most importantly, only use brake pads suitable for carbon wheels. “If your wheels have carbon braking surfaces, you have to take some special considerations into account,” warns Canyon. The use of carbon fibre allows manufacturers to make lightweight and/or aero rims but you don’t get the best braking surface. What you should look for instead is when the woven fibres of the carbon itself begin to become exposed or frayed.” They don’t work well in the wet Whilst they will curve inwards to a degree, this is not normally the tell-tale. Hunt's Ollie Gray says, “Carbon brake tracks are much more resilient than alloy braking surfaces and generally will not show the same bowing/caving that alloy surfaces do. Underneath this top layer is the raw carbon weave. Wheel manufacturers make rims from aluminium because it’s lightweight and the coefficient of friction doesn’t drop to the same extent as steel when it gets wet, but the aluminium alloys used are relatively soft and wear much faster.Ĭarbon fibre rims usually have a layer of material laid over the brake track to give a good braking performance, prevent heat buildup and prolong the life of the rim. Manufacturers will sometimes use a thin sidewall to reduce weight, but that’ll affect longevity. If you can avoid excessively dragging the brakes and if you clean your bike regularly, paying particular attention to the braking track on the wheels and the face of the brake pad you'll significantly extend the life of your wheels." How long you can expect a rim to last? Shimano's Ben Hillsdon says, "It's difficult to say because it depends on the force of your braking and the cleanliness of your pads and your rim. > How to tell when your wheel rims have worn out - and how to make them last longer That might not be a big deal if you’re running cheap wheels and you don’t rack up big miles, but it can get you down if you’ve just invested a lot of money in a set of posh new hoops. With disc brakes, it’s relatively inexpensive and easy to replace the rotors, but with rim brakes, it’s the sidewalls of your rims. You can, though, decide which components get worn. ![]() Braking causes wear – you can’t get away from that fact. ![]()
