I apologise as I remember there were some tyre width discussions a year ago, but I couldn't find them.
Looks like I'm out of another cross season due to chronic injury, but the bug has transferred to another family member.
I'm building an entry cross bike up for my sister using one of my old road frames and cross forks. If she likes it we'll get a better set up for next year, but this will do for now.
Amazingly It all works, but to enhance rear clearance I'd like a tyre that's actual measured width is 28mm.
I'm after a clincher, but NOT a file tread as there will be some muddy use.
I'm not concerned with the technicalities of handling that an experienced rider would notice.
(I'm in the UK so that may effect what's available.)
