i have a 50 triumph 6t hardtail. looking to run an hd style spoke rim on the back. i found a big twin duel flange wheel 16x3 for a good price. the caliper/disc seems simple enought but i thought i read somewhere that the hub on an hd wheel won't line up and the rim/tire has to be offset to one side to align the sprocket from the trans to the wheel. anyone clue me in on this? what do i need to do to set the hd up in my pre-unit?
