CyberRear freewheel mechanisms are suitable for road and cyclocross use (and not MTB), minimum 1.00 gear ratio.
Shorter ratios may result in high torque and damage freewheel mechanism
Dimensions for wheel building
- Spoke hole Ø: 2.6mm
- Left flange drilling Ø: 29.5mm
- Centre to left flange: 42mm
- Centre to right flange: 19mm
- Right flange drilling Ø: 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.
