Compared to CyberFront SL is an huge oversizing.
Radial lacing is allowed on internal and external flange side and only with D/B spokes (central section equivalent to Ø 1.5mm).
Micro-tuner allows an easy and quick bearing preload adjustment, no-tools required!
External OR-Seals are included, useful in muddy condition, removable for decrease rollling resistance.
To minimize torsional static forces flanges self-align under spoke lacing tension.
Flanges recive our new special treatments (military standard) to handle radial lacing stress.
Hi-performing custom wheels have never been that easy to build.
