As every Extralite products UltraHubs exceede UNI/DIN Safety standards. Safety tests simulate a very strong 90kg (200lb) rider output.
|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. Hi-performing custom wheels have never been that easy to build.
