53x12 = 119.2 inches 99 rpms.

50x11 = 122.7 inches 96 rpms.
53x11 = 130 inches 90 rpms.


One thing is likely certain, I will not be in the top gear for the final sprint.. lol I'm not strong enough to turn a big gear like that... It is more likely that I'll be in the 50x15/14/13 or something more manageable.
