I Have a Serotta frame and am having trouble mounting the rear derailer. I think they call them 3DXL dropouts, do I need an adapter? Or am I just an idiot? Trying to mount a 105.

Could you explain the specific problem you are having in more detail? I'm having a hard time picturing in my mind what your difficulty might be.

Every rear derailleur and bike frame I've seen in the past 20 years has 10mm x 1mm threading and they all match up. I have no idea what "adapter" you may need. We need a better description of the problem.

Thanks for the replies guys, I finally figured it out. It was just my inexperience showing.
