Description
A disk-specific design allows for optimised aerodynamics while the low weight is an important part of the lively, responsive feel and streamlined performance of these wheels in all weather conditions.
The rim is 22mm wide internally, with an external 30.5mm width optimised for best aerodynamic performance with tyres measuring around 25-28mm. The large width allows for lower tyre pressures without increasing rolling resistance – we recommend 60-80psi for most riders. Rim depths are from 30mm to 50mm for either lighter weight, or greater aero benefits.
The Mahi Mahi disk rim was developed over 3 years working with our rim supplier to perfect the tubeless fit. The result is a semi-hooked sidewall design which fits tubed or tubeless tyres securely and easily and offers excellent impact resistance, making it suitable for road or gravel. This rim design is suitable for running tyre pressures up to 100psi with 25mm tubeless tyres where the tyre specs allow (though we recommend much lower pressure for better ride quality).

30mm rims are our lightest weight wheelset with good aerodynamic performance. These wheels are light for hill climbing but roll fast on the flat too.
40mm is the best all-round depth and with a weight of just 1433g per pair and little affect from side-winds we recommend them for anyone.
50mm wheels are very fast with great aerodynamic performance at the expense of a bit more weight. These are the deepest rims normally used on standard road bikes.
