Hm. So I assume 105% isn’t a priority for you. I don’t think I’ve seen anyone use a 23 on a 23 rim, but I guess I have seen 23s recommended for 21mm rims - and the Vittoria tire is wider than normal. That being said I’m going to err towards safety and get the 25 and see how that works first. I’ll probably post up here with my experience in the next month or so when I gather the willpower to pull the trigger.
