    Default Shovelhead wheel identification

    I scored a 16x3 rear today at a good price, which I plan to rebuild for my 78í shovel project. Iím of the understanding that late 70ís irons and shovels had a similar appearance but the hub had a different offset, I also have seen post 84í dual flange hubs and Iím unsure if they would work. Iím hoping in which case that I got a compatible wheel for my project, any help in identifying?

    Are the flanges the same offset on either side? Then it's a Shovelhead wheel. If the brake side is noticeably farther out then it's for a '79-'81 Sportster. The hub below is the '79-81 Sportster hub.

    Thanks MOther, I checked and the flanges have the same offset on both sides, a 2” center bore, 3/8 holes and 7/16 holes on the other flange so I lucked out and got a shovel rear it would appear.

    The holes for the bolts should be the same on both sides, 7/16+. It appears from the pics that lock rings and washers retain the seal spacers. If so, and the flanges are symmetrical as to the spacing, it's a shovel wheel. Unusual for a shovel wheel to have an 11 1/2" rotor.

    Good eye Jim, it is odd to have a 11.5” rotor especially with a 2” center bore. I’m gonna pull the rotor today and check the holes, it might be 7/16 and I’m not catching the measurement correctly as the bolts are still holding the rotor in place.

    Yes, and the rotor pictured is correct for that period.

    Dragstews you think it’s worth it to go with the 11.5 over 10? A guy local to me is selling a complete swingarm with banana caliper and bracket for $100, here’s a pic Click image for larger version.

    Jump on that. The larger rotor gives better braking, and that bracket is a BIG improvement.
