Hi everyone. My question today is what are the benefits of having a larger chainring? Also, for those of you who run big gears, what do you suggest? I currently run 48x15 and the next obvious one would be 48x14. But maybe that's still not a big difference for what I need. To give you an idea about my fitness level. Yesterday I pedaled an outdoor, windy, flat track going 20-21 mph for 1hr and 20mins, no water, no stopping, with at least 1 sprint for every 2 miles.
