I understand that. I put 23s on when I was using it for club runs in the winter as I didn't want wider tyres slowing me down. Now I've done a full winter as a club member I realise that guys turn up on all sorts and I'd be more than comfortable on something a bit more forgiving. I may return to 25s, we'll see.Lejogger, IMHO the only thing that lets the entire Boardman range down is Halfords. I'm one of the lucky few that have a store that is run by people who know their stuff.Both the CX and the TC are great bikes and at great prices. I'm not sure that I'll put 23's on the CX though. I want a more comfortable ride on that bike.
Halfords have a poor reputation and I must admit, I wouldn't let some of the staff in my local branch loose on a wind up alarm clock, let alone any of my bikes... but the two or three guys in there who are the ones trained up to build and maintain the Boardmans are actually very competent and knowledgeable, and I let them carry out the jobs I can't do or don't have the tools for.
