I have a used 57cm Independent Fabrication Titanium Planet X Cyclocross frameset for sale. It comes with frame and the original steel IF fork with disc mounts. The rear dropouts were converted to Paragon Machine Works Rocker dropouts by IF. Adding the PMW rocker dropouts gives you the option of converting your bike from multisided to single speed a snap with the added option of carbon drive.

I recently sent this frame back to IF due to some tire rub on the inside of the non-drive chain stay. They looked over the entire frame, did a minor repair (see photos) and sent it back. I have not built it back up since. This was mainly used as a single speed gravel bike.

I have included the build sheet from IF in the photos with all measurements. Please ask all questions before you make a purchase or offer - thanks!
