Boost rear hub on Sunringle Duroc 35 rim ca 2018 https://cimg3.ibsrv.net/gimg/bikefor...7838d80438.jpg Boost front hub on Sunringle Duroc 35 rim ca 2018 Is anyone able to ID these hubs? Looking for a service guide or manual, will eventually need freehub parts. These were on a 2018 Silverback MTB. These are laced to Sunringle Duroc 35 rims and are very strong wheels but I've been unable to find any corresponding Hayes or Sunringle products. Thanks! |
Probably a Formula or Novatec hub if built by the manufacturer if not it could just be a built wheel from Sun Ringle which might be their own hub or again that Formula or similar?

almost certainly Formula Hubs... they are fond of the Oval, kidney bean shaped holes in the spoke flanges..
Novatek (somewhat upscale Joytek, really) prefers a rounded triangular hole in their flanges. Formula makes most of the "Rebranded" hubs sold on bikes. hard to see in the pic, but the rear hub appears to have a 45*-ish taper just inside of the drive side spoke flange too, with a rounded shoulder where it meets the minor central hub diameter... another Formula favorite. |

I still can't find anything even similar - this hub has a simple axle - 17mm with a single step that sits between the freehub and wheel bearings. The hub has 2 17287 bearings on the brake side, a single 17287 bearing on the drive side, 2 17287 bearings in the freehub itself. It seems really solid yet failed at a <500km due to the hub preload spacer being too short and over loading the bearings. Frustrating that even the spokes are labelled - but the hub itself is not. Edit: photos showing the shape of the rear hub better, and the format of the serial number (B0030-1810). Serial number is microscopic and on behind the rotor mount, is the only marking I can find on either hub. Edit 2: has 5 pawl freehub, pawls and springs are retained with a wide flat circlip Edit 3: Hayes/Sunringle have confirmed it is not one of their hubs :-( Edit 4: Formula confirm this is NOT one of their hubs. https://cimg1.ibsrv.net/gimg/bikefor...4bcb5e41d6.jpg https://cimg2.ibsrv.net/gimg/bikefor...c98d8487f3.jpg |
