Does anybody know where suitable cones for Shimano HB-6400 front hub (600 series) can be obtained? Original or any that would do the job!!
I believe the part number is Y37798060 and is M9 x 11.3mm long, with a 1.75mm wide groove x 1.5mm deep to accommodate the seal.
I have searched the net, but alas, cannot find one anywhere.
With all the knowledge that lies out there, I am sure that someone can help.
The closest that I have found is a Shimano HB-A410 Complete Axle, from SJS cycles, the cones look similar but are 10.5mm long, a washer will cure any OLN distance problems.
