Shimano Dura-Ace Track HB-7710 Rear Hub

While the HB-7710 is engineered specifically for the demands of track cycling and velodrome racing, it is a popular choice for fixed-gear street riders due to its legendary durability and smooth bearing performance. Keep in mind that it is a single-sided fixed hub, so you cannot run a freewheel or a flip-flop setup.

The drilling count should match the spoke count of your rim. Generally, 32h is the standard for most track wheels, offering a balanced mix of weight and stiffness, while 28h is often preferred for lighter, aero-focused builds and 36h is best for riders prioritizing maximum durability or those using heavier-duty rims.

This hub features standard track spacing, which is typically 120mm. Before purchasing, verify that your frame's rear dropout spacing is 120mm to ensure a proper fit without needing to cold-set or modify your frame.
