    Dimensions for wheel building
    • Spoke hole : 2.6mm
    • Left flange drilling : 29.5mm
    • Centre to left flange: 42mm
    • Centre to right flange: 19mm
    • Right flange drilling : 52mm


    16+8 lacing allows a laterally stiffer wheel.

    More spokes on drive side and more tensioned on non drive side.

    Spoke tension of the NDS is 90% of DS, this allows the DS spoke tension to be lower and the wheel to be built more like a front wheel.

    Compatible with standard and triplet specific rims.

    On standard rims spoke holes must be with vertical drilling. Angled drillings are not compatible.

    Oversized titanium ratchet wheel with a precise 32T pawl engaging system.

    Drive side spokes are more and more tangent to effectively transmit the torque.

    NDS flanges has a carbon fibre reinforcement to support higher radial tensions.

    Micro-tuner: our easy and quick external bearing preload system that ensures precise tuning, smooth running and no play at the rim.

    4-bearing design for long lasting performance.

    Equipped with ABEC5 cartridge bearings featuring Grade 5 Chromium Steel Balls, 52100 Hi-Carbon Chromium Alloy Races, Nylon-Graphite Ball Retainers. Fully serviceable.

    Very light: a weight nearly as low as hybrid ceramic versions.

    Special low friction SRS axial seals on main hub bearings, 2RS protective seals on freewheel bearings.

    Hi-tech rarely combines with maintenance easiness, not here!

    As with all Extralite products CyberHubs exceed UNI/DIN Safety standards.
