It beggars belief for me. I can't understand people who fear the little ring like this, i'm on it quite a lot, and one of my bikes won't safely engage 53-25 due to me deliberately setting the chain length so as to limit me to 53-21. I think people just see stronger riders, mostly on TV, living on the big ring and think it's the way to go. I once saw someone grinding his way up otley chevin on the big ring at the front and what looked to be a 32 at the rear; his rear mech was as straight as a 6" rule!
