DISCONTINUED ITEM. Please click through to see our current range of Shimano Front Cones & Axles.

Replacement hub axle with right cone for Shimano HB-7800 (Dura-Ace) hub.

Shimano Part Number: Y25R98040. Shipping Weight: 37g.

When servicing a hub or replacing cones we recommend that you always replace the balls.

The HB-7800 was made in two configurations - the A type used 3/16" balls x 28 (14 per side) but the B-type used a ball retainer (Y25R98080) that we do not stock.

For this quality of hub we recommend you use Grade 5 balls (very high quality).
