I have an older mountain bike and I would like to replace its stem with a 1" diameter stem. However, my bike currently has a 1-1/8" diameter stem. Can I get a shim that I can insert into my threaded headset that would allow me to use a stem that is sized for a 1" threaded headset with my bike?
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Several year ago I was looking for exactly that type of adapter as I wanted to use an existing set of 1" road bars and stem to convert a Trek hardtail MTB for drop bar use and the Trek had a 1-1/8" headset/fork. I never found one and wound up buying a 1-1/8" quill stem. It wasn't that easy to locate either.
