Shimano HB-M525 Front Cone M9

The Shimano cone has now been replaced by an equally good cone from Wheels Manufacturing. Our advice is that Shimano has discontinued its cone, so we had to source these elsewhere. So far they look to be as good as the manufacturer says they are.

Suits HB-M525 (Deore - Disc), HB-M510 (Deore), HB-MC33 (STX-RC), HB-MC32 (STX), HB-MC30 (STX). Also can be used in place of discontinued Shimano Part Number Y21498020 which suited HB-1055/1056/6400 but will need the steel dust cover removed (see "More details").

M9 x 11.5mm. Steel dustcap included.

Shimano (discontinued) Part Number: Y21L98020. Weight: 10g.

When servicing a hub we recommend you always replace the balls.

A hub that uses this cone will use 3/16" balls x 20 (10 per side).

We recommend using Grade 25 balls with these cones. You can click the links on the right to both the individual balls and also to boxes of 100 (a more economical way to buy them).
