I'm trying to change out my bars..How can i tell what size clamp I have on my bike? I know it's not oversized 31.8--but what about 26 or 25.8? There's no size on the bar or the stem. I measured the bar around and came up with 8.5 cm around if that makes any sense. thanks
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

It's not the same issue. Handlebar clamps will tolerate minor diameter differences and 25.8 and 26.0 are considered interchangable. 25.4 in a 26.0 or vice-versa is considered too much of a mis-match but 25.8 and 26.0 are compatible.
With a ruler, it would actually be a difference of (26.0-25.8)*3.14 = 0.628mm. Certainly possible to measure. Easy way is to cut a strip of paper and wrap it around the bar. Mark and trim it to length to perfectly wrap around the bar. Then measure that paper with a ruler.
