I've been running 700x23 clinchers and have always purchased 700x18/25 butyl tubes but just found a bunch of tubes I must have ordered last year that are 700x19/23. They look way narrower and was just wondering if that is a big deal or not and if there is any pro's or con's?

When I do re-order tubes would you suggest 700x19/23 or 700x18/25 for 700x23 tires?

Thanks,

doesn't make a difference at all

Whatever's lightest!
