  • Selection 25T

    The wheelsets of our SELECTION line represent the entry into the ax-lightness wheelset family.
    Nonetheless it is not being cut back on the quality or qualities of the wheels. The Selection wheels share our same high-end German-made rims that shine with their unparalleled lightness and high stability.

    The SELECTION wheelsets are a synonym for an uncompromising reliability even under severe conditions, without sacrificing the special ax qualities such as light weight, high stiffness or low moment of inertia.

    On the hub side from MY2018 we are utilizing a hub with carbon shell specifically made for us (AX Road Carbon HRC-017 hub) which not only visually but also technically compliment the SELECTION wheelsets very well thanks to their light weights of just 72 respectively 215 g, but also due to their high reliability thanks to multi-sealed ball bearings as well as an intelligent geometry and the use of straight pull spokes.

    Axle System: front: 100mm ; rear: 130mm

    Laminated spoke holes

    Instead of simply drilling the spoke holes of our rims, we take a different approach with our rims: Every single spoke hole is crafted by hand and reinforced with strategically placed reinforcement patches.
    The advantage is obvious: Where carbon is being drilled, one inevitably also cuts through fibres. A continuous fibre flow however is essential for the material to play its advantages such as the high tensile strength, even more indispensable for nipple holes that are exposed to high spoke tensions. Specifically crafted nipple seats allow an optimal orientation of the nipples and at the same time distribute the occurring forces evenly into the rim bed.

    Independent testing at an university lab has confirmed the performance of this time and labour intensive approach: The rim is capable of withstanding nipple pulling forces of over 5000 N - circa twice as much as the best competitor and more than every hub flange or spoke would be able to endure. As a result our rims do not carry any spoke tension limit!

    Us ourselves we are building our wheels with up to 140 kg of a spoke tension: A guarantor for you to have long-lasting joy with your wheels. The higher the spoke tension, the lesser the opportunity for a spoke to be unloaded upon an overload of the wheels (e.g. from a compression such as an obstacle, pothole or anything alike) and the wheels to therewith come out of true. That way you are longer able to ride with your perfectly trued wheels. As an additional advantage there also is minor increase in stiffness to be recorded.
    An effort that pays off!

    Hand-built

    All of our wheelsets are individually built by hand in our manufacture in Creußen, Bayern, to the tightest tolerances and with extremely high spoke tension. We refrain from the use of wheel building machines and invariably trust on the craftsmanship of specially qualified mechanics. The high experience with high-end-material allows a consistently high quality, the tight tolerance in lateral runout and radial runout a perfect runout and therewith a lot of joy with the wheels.
