i'm very new to track racing, and have only been to one training session. during this session, we did a few exercises where i felt i was spinning out of my gear (i.e. flying 200, one lap scratch). i am running 51-17. it was suggested that a 15 tooth cog would do me better.
my flip flop hub is fixed/free. is it a bad idea to rotafix a 15 to my free side, sans lockring, solely for track use? the 17 cog with lockring would get me to and from the track.
i am ultimately planning on building a new rear with a 15-17 flop, and getting ahold of an extra chainring or two. since my bike budget is nil for the next month, and i my first race night is a week away, i'd like to bump up the gear asap. i can afford a cog.
or should i just learn to spin in the meantime?
