So I was trying to get the rear wheel all dialed in this weekend. I used square box tubing across the front and rear sprockets to get the sprockets lined up. Now my problem is that my wheel needs to shift over 5/8Ē to be centered and to allow for my rear caliper mount. So Iím thinking that Iím going to need an offset front sprocket. Does that sound correct? The rim I have is a brand new tc broís 16x3. Also I still have the slightest bind at the front sprocket. Could this just be from and old worn out front sprocket. I donít know if this helps but the front sprocket is 21 tooth and the rear is 48 tooth the bike is a 1980 sportster. Never thought mounting the rear wheel would be this much of a pain ha ha ha.
