Use limitation for Carbon Wheels
Standard carbon wheels are designed for light weight and high performance use. The overwhelming majority of high performance cyclist are light weight people, accordingly carbon wheels are not designed for heavy riders and therefore have a weight limit rating on them:
- Carbon wheel with a profile below 45mm: 90Kg (total weight of rider, bicycle and equipment)
- Carbon wheel with a profile of 45mm and above: 100Kg (total weight of rider, bicycle and equipment)
- Carbon wheels are not designed for tandem bicycle use.
If you are a heavier rider, intend to carry significant load on your bicycle, intend to make significant jumps, ride downhill off road, or the wheels are intended for a tandem, standard competitive lightweight carbon wheels are likely not adapted for your intended use. Please contact us so we can propose wheels that are properly designed for your use profile.
Air Pressure and Braking
Carbon wheels with rim brakes generate significant heat from braking. Epoxy resins used in carbon composite are less temperature resistant than aluminium. The heat does not dissipate as well as with aluminium rims. These facts create limitations with regards to braking and air pressure in the use of carbon rims.
For clincher and tubeless tires, the maximum inflating pressure of a cold tire and rim is 8 bars or 116 psi.
For tubular tires, the maximum pressure should be the maximum pressure recommended by the manufacturer minus 10%. Please follow the glueing instructions and use the glueing materials recommended by the tubular manufacturer.
