This Shimano 105 HB-R7070 front disc hub is designed for cyclists seeking a durable and smooth-rolling front wheel solution for their disc brake-equipped bicycles. Its key benefit lies in its reliable performance and secure Center Lock disc rotor mounting. A potential caveat for some users might be the requirement for specific 100 x 12 mm thru-axle frames and forks, as the axle is not included. The hub features high-quality sealing, a cold-forged aluminum shell, and a special Boron Nitride machining process on the cones for enhanced rotation.

Center Lock offers a simpler and more secure way to mount disc brake rotors compared to the older 6-bolt system. It typically requires fewer tools for installation and removal.
No, the Shimano 105 HB-R7070 front disc hub does not include the 100 x 12 mm thru-axle. This must be purchased separately.
This hub is ideal for disc brake-equipped road bikes, cyclocross bikes, gravel bikes, and some touring or commuting bikes that utilize a 100 x 12 mm thru-axle standard.
The Labyrinth and contact seals are designed for low maintenance. Avoid pressure washing directly at the hub. Keep the exterior clean, and consider a professional service for bearing checks and re-greasing periodically.
No, this hub is specifically designed for a 12 mm thru-axle and is not compatible with traditional quick-release skewers.
The internal grease sleeve helps to ensure that grease is evenly distributed throughout the bearings, providing long-lasting lubrication and further protecting against contaminants.
While durable, the 105 series is generally geared towards road and gravel applications. For heavy-duty mountain biking, hubs with higher specifications (e.g., Deore XT, XTR) might be more appropriate, though this hub can perform adequately for light trail use.
The cones may need adjustment, or the bearings may require cleaning and re-greasing. Consult a bike mechanic if you are not familiar with bearing adjustments.
Check that the Center Lock rotor is correctly installed and the lockring is tightened to the specified torque. Ensure the rotor itself is not damaged or warped.
Verify that you are using the correct 100 x 12 mm thru-axle and that the frame/fork's internal threads are clean and undamaged.
The hub's bearing preload needs adjustment. This typically requires specialized tools and knowledge; professional adjustment is recommended.
Compatibility: This hub is designed for frames and forks with 100 mm hub spacing and 12 mm thru-axle dropouts. It uses the Shimano Center Lock system for disc brake rotor mounting. Ensure your wheel rim and spokes are compatible with a 32-hole hub drilling. The required 100 x 12 mm thru-axle is sold separately.
Setup:
Care: Regularly clean the exterior of the hub with a damp cloth. Avoid high-pressure water jets directed at the hub seals. While the seals are excellent, periodic maintenance by a qualified mechanic to check bearing adjustment and re-grease the internal grease sleeve is recommended, especially after extensive use in harsh conditions.
