The Shimano RS770 Front Disc Hub is a lightweight Center Lock hub that provides the pro-proven performance of Shimano's top-of-the-line componentry at a more affordable price. Featuring double-sealed bearings and a 12mm E-Thru axle, the RS770 hub is designed for increasing torsional stiffness and smooth-rolling comfort. Based on the design of their 6800 hubs, when paired with the RS770 rear hub, the pair shaves nearly 60 grams off the total weight of its predecessor.


  • Compatible with Center Lock rotors.
  • 12mm E-Thru Axle system.
  • 32 hole hub.
  • Weight: 126 grams.

Economical 12x100 TA with loose ball bearings

Built up a set of these hubs to HED Belgium rims and they are bomb proof. Requires a 17mm and 22mm to open the front hub, but overall it's a pretty standard loose ball Shimano hub. It doesn't have the digital adjustments that the last Ultegra and DA hubs had though.

Rare combination

One of only a couple centerlock disc brake, 12x100 thru axle hubs with 36 holes on the market so it was a no braner for me.
