Today I tried a few different gear ratios to see which one would yield me the fastest time. I just wanted to confirm the gear I used last year would yield me the fastest time. It was confirmed that a 108 inch gear (52x13) would give me the fastest time. Today was not an ideal day for time trials, it was hazy, hot, humid and very windy, with a threat of thunderstorms. The 108 inch gear was used for my third effort, considering I would have been a bit tired from the previous two efforts, it still yielded the fastest time. Just for good measure I tried a 117 inch gear (52x12) and I was surprised I was able to do the same time as my second effort, but the profile was a bit erractic since I could not keep the rpms up. If you notice the profile for effort number three in the 108 inch gear, is very smooth with a high top end speed. This shows I am able to get the gear up to a high top end speed and maintain the rpms. I am still hoping to break the 12 second barrier before the end of the season.

Below is the Garmin GPS video profile of Effort #3 in the 108 inch gear.
