Hi all, I have a question about rear wheels. I have a 2010 heritage, and I want to get an extra rear wheel to try and seal the spokes so i can go tubeless. I did it on the front and it worked ok so far (knock on wood). On ebay they have a rear spoked wheel from a 2004 Sportster, with a 3/4 axle. Is the wheel the same, and I just have to put in 23mm bearings, and I'm good to go, or are there other things I'm not seeing? Thanks.
