Shimano Part Number: Y3TG98030. Weight: 93g. Re using this in FH-M775, this is a "class B" interchangeable item according to Shimano - this means it is fully interchangeable but has some cosmetic difference. As far as we can tell, the difference is in the left side "locknut" which is scalloped out slightly. As they're almost identical, we're reusing the photo from the FH-M775 axle kit.Shimano Part Number of FH-M775 Rear Axle Kit is Y3D098050.
We recommend always replacing the balls when servicing a hub or replacing cones.
The FH-M770, FH-M775 and FH-M785 rear hubs use loose balls on the drive side (3/16" x 13) and a ball retainer (part number Y26J98030) on the non-drive side.
We recommend using Grade 5 balls (top quality balls) with these cones.
You can use the links on the right to go directly to the recommended retainer and balls - either individually or in the relatively economical pack of 50.
