Bought a frame that has just the cups of the old headset left in, but they have no identification on them. I know there are now loads of different sizes etc, but what are the chances of being able to use the cups as they are and fill them with the guts of a new headset? Pretty slim is my guess, but thought I would ask the STW mind before I have to get a new headset fitted (which was quoted to me as £55 for a Cane Creek as the only one they had in)
Thanks
