Up front and Center Locked.

Complementing the new Ultegra R8000 lineup, the brand new Shimano RS770 Front Disc Hub provides the pro-proven performance of Shimano's top-of-the-line componentry, yet at a new, more affordable price. Featuring a lightweight construction designed to increase stiffness and handling without sacrificing comfort, the RS770 front hub is designed around the 12mm E-Thru Axle standard, perfectly complementing your road or 'cross bike. When combined with the matching RS770 Rear Disc Hub, this hubset saves you almost 60 grams over the previous 6800 hubset, even while adding Center Lock and E-Thru Axle compatibility.


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

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.

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.
