Shimano's highest grade road component series, Dura Ace's front hub HB-9000, is manufactured by combining a high quality aluminum body with a lightweight aluminum axle.
And the cone ball bearings are made of stainless steel with Shimano's unique top quality finish, and the latest technology digital cone bearing adjustment system makes hub bearing play easy with a 5mm Allen key. I can do it.
This model is the last single Dura-Ace grade hub currently available.
As the number is limited, please do as soon as possible!

Digital cone bearing adjustment system
The digital bearing adjustment system makes maintenance easier and easier to adjust and maintain. Digital adjustment without double lock allows accurate bearing adjustment with just a 5mm hex wrench.
