Dropouts Not Using Derailleur Hangers

Several dropouts have hangers but aren't using them. Instead, the derailleur is mounted to the axle.

Affected:

  • Allotec C23
  • Allotec C49
  • Allotec C64
  • Artefact DR30
  • Coast Cycles

Everything else appears to be correct. Went through every static drawing with a transparent derailluer to check. :)

Unless there's an option I'm missing? But then it'd be odd that others are auto detected.

Derailleur hangers

Thanks for bringing this to my attention. I believe this might have cropped up since the option to add T-Type derailleurs was added. I'm surprised I missed so many dropouts with hangers. However, I have corrected this for the next version and I appreciate your assistance.
