So I have a 90s Nigel dean racing frame in 531c. I bought a set of wheels on here (Easton EA70s). I’ve coldest the frame to 130 spacing but The rear wheel does not sit central between the seat stays at the brake bridge - the gap between the rim and stays is asymmetric measuring 21mm on the ds and 25mm on the nds.
Things I have done:
Checked wheel dish - wheel is equal and fine.
Checked dropout symmetry with string - pretty close to being equal at the seat tube.
Tried another (older) wheel - which sits central.
Adjusted dropout screws to get wheel centred at chainstay/bb.
Because an older wheel sits true I’m wondering if the issue is to do with dropout/wheel interface so the wheel is not sitting vertically and i need to realign dropouts - although I can’t quite see how they can be so far out to cause the 4mm different at the brake bridge.
Any thinking on what to do /try next much appreciated.
