• Aero Carbon Road & Disc

    The new 38/50/65mm Tubeless-Ready Clincher rims feature a full "pre-preg" carbon from F1 technology.

    No applied laminated brake track, just a raw carbon surface.

    High temperature resilient.

    Very similar to ENVE in construction but without the "cheesgrater" braking surface. Same durability - they don't wear much at all over the years if pads are kept clean.

    Braking is superb and we have yet to see a melted rim - despite deliberate testing on Bealach na Ba, Honister Pass, Alps, Dolomites etc.


    Choose these over the Dimpled rims if you don't want dimples! Aerodynamics and braking dynamics are are so similar we can't make a call on it.  


    We now have 38mm, 50mm & 65mm DISC rims. Tubeless clincher design.

    26.5mm external. 20mm internal.


    We have 45mm & 77mm TL Disc rims for 28mm tyre integration. They are 22mm internal, 28mm at the hook and 30mm at the widest part. Super aero and will be used for a tandem world record challenge later in the year. The 77mm rims are more expensive than our other rims as they are our own mould and design. 


    Build up to 1450g and 1530g respectively with DT240s for example. Designed for a 25mm tyre but will integrate well with a 28mm tyre too.

    Fast, stiff, very aero and with a rider weight limit of 100kg.

    Price is per pair and includes:

    Sapim CX-Ray spokes
    Sapim brass nipples
    Titanium skewers on rim brake versions only
    Full set of pads for rim brake versions
    Stan's rimtape for clincher and tubeless ready clinchers

    Available with or without decals. See HERE for new decals.

    Shimano free hub bodies for all hub choices are 11sp, with spacers for 8/9/10sp supplied. Campagnolo are inherently 8/9/10/11sp compatible


    All these rims are now UCI approved.
