• was 10 in each side, does that ring true?

    Which hub? Traditional (i.e. 9mm steel axle, not the latest fat axle models) Shimano spec is 11 of 3/16" per side in a front hub.

  • It's the traditional hollow steel (also marked 'HR 6400' and with the little three band green/blue logo on the black sticker running around the hub body, like the one attached) so sounds like I'm a bearing short (as usual, in so many ways).
    Cheers @mdcc_tester, off to the shop then.

    HB-6400, and oddly 10 per side is right for that hub, I guess they were chasing light weight by reducing the cup and cone size. 6500 is the same, but they went back to 11 a side for 6600 and 6700 before changing to fat axles for 6800
