Hey guys, I'm in the process of installing a new groupset onto a vintage frame. I spaced out the rear from 126 to 130 and have used the string method to ensure frame is aligned (about 35mm either side of seatpost tube) but can't get the wheel to sit centered for the life of me. When i have the axles all the way back in the dropouts the wheel hits the non driveside stay. I've tried using a homemade tool to ensure the dropouts are aligned with each other but i think my non driveside stay is longer than the drive side chainstay :S is this a possibility and possibly a manufacturing flaw? I can get the wheel centered by having the left side half way up the dropout and the right all the way in to factor for the lobger stay but is it safe to ride this way?
