I know this is an old post but I only just came across it and realised this is my frame. I rebuilt it after you returned it to me and have been riding it ever since. The rebuild included new chain stays, sliding dropouts and removal of the brake bosses. These frames new are now nearly £2000. Also, there’s so much clearance in the rear triangle that it enabled me to build it as a 650b. It’s an amazing bike. I’m currently in the process of stripping and refinishing it again. It just doesn’t want to die. It will look very different from these photos when completed.
