The frame I'm looking at is stock with standard dropouts and derailleur hanger, I will be setting the new bike up as a SS. Having the frame custom made with track ends is an option, for an extra $300. My current CX bike is set up with a White Industries eccentric hub, I have not had any problems with this set up what so ever. I was wondering if track ends would be any better than the WI eccentric hub? My last experience with track ends was on my BMX bike in the 80's.
