Ideally, I would like to get a 126 or 130 OLD hub thats 9 spd. I was looking for older Ultegra because I wanted to go with a 9spd ultegra hyperglide casette. I have never built a wheel before but planned on removing the spokes and re-using the rim.I am a complete newb and just learning about axle spacing. The bike was a craigslist find, and I couldnt get it to shift properly with any amount of limit and b screw tuning. Then I realized the dropout didn't look straight and the derailleur hanger was at an angle.
