I emailed someone about some Cinelli handlebars he was offering for sale to find out what clamp diameter they were, and he says they are 26.2. I can't find any info about 26.2 stems or bars and I am wondering if these really exist. I know that a lot of vintage Cinelli bars had 26.4 diameter, and some had 26.0, but I wasn't aware that they also came in 26.2? Is it safe to assume that these are 26.4 and it is just a mis-measure, since .2mm is pretty easy to miss with most calipers?
