Recently added a Park DAG-2 derailleur hanger alignment guage to my tool collection.
Checked alignment on my carbon frame, '09 S-Works Tarmac ... mildly surprised to measure it beyond Park's recommended tolerance of +/- 4 mm (measured at wheel rim).
Mine was up to 10mm off :-O
The Campy 11 speed shifts fine, but now I'm thinking maybe it could be even better, and I didn't know what I've been missing.
My question: Is it safe to attempt bending the aluminum hanger back into correct alignment, while the hanger and wheel are clamped inside the carbon frame?
Last thing I need, is cracking the carbon fiber drop-outs!
Alternatively, trying to bend the hanger when it's removed from bike seems safer, but more hit-and-miss.
