I established this afternoon that my '94 GT Pro Series Team frame has a 11/8" headtube. The fork I have in the the frame is 1" threaded. There was a headset fitted as you can see in the pic but the bearings didn't fit snugly and turning was a dog - so I tried to fit a nice OS GT headset - BUT the cups are too narrow...
Are headsets for 1" threaded forks available to fit 1 1/8" headtubes? or do I just need large bearing races?
Anybody got some savvy advice please.
thanks.
