    Specifically designed for Road disc use.

    4-bearing design for long lasting performance.

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

    Straight pull spokes increase wheel stiffness under sprinting. They appreciably reduce lateral flex and increase torque transmission reactivity. All this comes with a noticeable weight reduction too!

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

    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.
