Have your say: MSA front and rear hub regs
An update to the following rule has been proposed for 1st January 2017:
(U)16.8.4. Hubs with a single retaining bolt feature must not protrude beyond the end of the axle, unless designed for that purpose, and must incorporate a retaining device.
Rear hubs must cover the axle by a minimum of 40mm, and front hubs must cover the stub axle by a minimum of 30mm.
Clarification. To address confusing and potentially contradictory regulations that in reality are too complex and difficult to enforce.
