I am uncertain why it is so hard to understand that I spin out on 50/12 on hills, but can continue with effective acceleration on 52/12. You guys keep vomiting up numbers and ratios while I am relaying practical experiences. Not trying to convince anyone of anything, just imparting what happens when I ride my bike.
