Does this hub require a lock ring
20 Nov 2020
Thank you for your response, my question was whether this hub requires a lock ring or not? The deluxe version specifically mentions that it does, where as there is no mention of needing one on the 28.
I appreciate I would have to buy one if it is needed.
The SON 28 does not include a lock ring- however, as its centerlock disk you do need to use a lockring.

Please note this hub requires a bolt through type lock ring for the fitting of the disc rotor. Shimano produces two which are SJSC part numbers 35943 and 40310.

Hi, neither the 28 nor Delux hubs are provided with lockrings.
