I'm currently running 48x14, I've done 2 Omnium events (Cat5) and finished 2nd and 3rd overall, and have won 2 scratch races in fields of 15-20. I have topped out at 130rpms running this ratio, so I know I need to get my spin faster. My question is...i have a 49t and was wondering if it's worth it to try out a 49x14, or to just work on spinning faster first. For what it's worth, the track I race on is a 400m track.
