so i took my bike to my LBS and the mechanic said i probably need a 1" stem (cause the stem on there does look like a 1") we didnt actually measure it. i wasnt there just to ask him what size stem i needed i was there for something else and out of the blue i just asked him if he knew what size i would need. so i ended up getting a 1" stem online but when i got it it was too big to fit. my frame and fork is an 86 schwinn sprint. is there anything smaller than a 1"?
