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!
Flanges recive our new special treatments (military standard) to handle radial lacing stress.
To minimize torsional static forces flanges self-align under spoke lacing tension.
