XD-15 ceramic bearings
Specifically designed for Road disc use.
4-bearing design for long lasting preformance.
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.
