CyberRear SPD lacing instructions

Specifically designed for Road disc use.

New 4-bearing design for long lasting preformance.

New 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.
