When I went to mount the tires tonight I noticed that they were labeled 22-622. So, I called Competitive Cyclist and asked if they were 700 or 622. Here's the answer and it's interesting.....They said they are labeled using "northern European" measurements. What? Apparently northern Europeans measure inside dimensions so 622 is the same as 700. So, is 22 the same as 23? I didn't think to ask but I'm betting it is.
