With a 45mm rim profile but only weighing 1390g, our RP45 LTD offers a compelling combination of high speed eficiency and weight.

The mini-hook opens up lots of tyre choices but it also improves the fit of the tyre to the rim, further enhancing aerodynamics. The top spec Zipp Cognition VS2 hub and Sapim spokes combined with our range topping rim ensure the highest performance and reliability.

Core technologies


For those who want the widest tyre choice, our RP road wheels use a wide, but not too wide, 21mm internal width, maximising compatability with tyres from 25-32mm.


A wheel isn’t just a rim, hub and spokes, rather a system which works together and where many elements have an effect on performance. Spoke tension makes a massive difference to the stiffness and feel of a wheel.
