Shimano 105 HB-R7000 Q/R Front Hub

Durable and smooth front 105 hub. Radial lacing compatible.

Cubic Boron Nitride treated cone races provide a mirror-smooth bearing surface for a low friction, corrosion-free performance.

Labyrinth and low-friction contact sealing effectively shuts out water and dirt without affecting rotational smoothness.

Internal O-rings help maintain and increase service life of front hub by holding the grease in the bearing housing.
