Just curious about something - can anyone tell me the pros/cons on wider v. narrower tires? I am currently running 21mm, and was looking at some new tires. One set is 19mm and the other set at 23 mm. The 19mm is supposed to be used by “triathletes, time trialists and road racers”, where the 23mm is supposed to be ideal for “road and stage races”.
Why would this matter? Lower rolling resistance on skinnier tires? More comfort on wider tires? Would it affect handling?
Thanks,
John
