  • Ultra 25C

    Ultra 25C - A completely new development! Thanks to a CfD-optimized rim profile our 25C Clincher rims offer an exceptional aero performance that matches those of significantly deeper rims.

    The low weight, which so far has only been reserved for tubular rims makes them miraculous accelerators and very reactive. The high stability is responsible for not wasting a single bit of energy or and a high steering precision.

    A special, patented coating on the brake track offers a secure braking perfomance in any conditions. The coating functions as isolator and keeps the occuring heat away from the inner part of the rim, effectively preventing a delamination or damage of the rim even under the most severe conditions. The rims have been tested at surface temperatures in excess of 400 degrees Celsius - without taking damage.

    Each rim is individually tested at a tire pressure of 13 bar prior to release which is a testament to their extreme stability.

    All of this make the Ultra 25C to the absolute king of the mountain!

    Ultra

    The wheelsets of our ULTRA line allow to enter new spheres thanks to the interaction of the most noble materials, exquisite components and elaborate manufacturing!

    Our ULTRA line comes with hubs from Italian brand EXTRALITE which not only manage to shine with their sensationally light weight but even more so with their intelligent and durable design and practical features such as a bearing preload adjuster.

    All of this paired with our superlight and just as stiff and durable rims yields a performance at the absolute top class! Cycling on Formula 1 level!

    Hand-built

    All of our wheelsets are built to the tightest tolerances and with extremely high spoke tension by hand in our company in Creußen, Bayern, and individually checked before being able to call themselves a real ax-lightness wheelset:
    An amount of work that is reflected in the final product and co-determines its extraordinary qualities!
