The new quick release Ursus WB05 in aluminum has been completely restyled to make it more manageable and stronger. It has the axle in CrMoLi and it is complete with lever and nuts in alloy.

The closure with eccentric system allows to modulate the force required to have a greater sensitivity to find the correct closure of the quick release.

The length of the axle is 150 mm for the front and 180mm for the rear. This quick release is assembled in the road racing wheels.
