The Shimano RS770 Rear Disc 32 hole Hub builds off the success of their previous Ultegra 6800 hub, adding in E-Thru Axle and disc brake compatibility.

Designed for stiffness, responsiveness, and comfort, the RS770 hubs offer greater stability and more efficient power transfer that comes straight from Shimano's top-of-the-line tech.

  • 10/11-speed compatible.
  • Hub width: 142mm.
  • Spoke holes: 32.

Economical 12x142 TA freehub with loose ball bearings

This is a pretty standard loose ball Shimano hub. It doesn't have the digital adjustment process that the last gen of Ultegra and DA hubs had, so you need 2x 17mm wrenches to open it up. I built it up on HED Belgium rims and the set is bomb proof. The freehub was sticking a bit when I first received it, but loosened up after the first ride. The bearing adjustment was off as wheel (too much play), but I opened it up, repacked the grease, and tightened it up and it's been fine for 500 miles. They roll really smooth and are incredibly inexpensive compared to other TA 12x148 roadgravel options (i.e. DT 240s, etc.)

Excellent Hubs

I used these hubs with DT SWISS R460 rims to build up some Winter rain riding wheels. They're Ultegra quality and work very well. The Shimano 105 rotors and Ultegra cassette installed easily on them. No brake caliper or derailleur adjustments were necessary after plugging the wheels into my Trek Checkpoint SL6 bike. So far, bearings smooth as silk after about 500 mi.
