I finished a two day last weekend. I was having trouble with the tight sections.(My clutch cable had broke) After the first loop I started to check out the gearing. I was running 13 and 46. My riding buddy had 12 and 46, and had been doing quite better in the sections. We compared thoughts and agreed the 11t might even be the best choice. Both of us had 199`s and we compete on modern bikes in the same class. You can always ride a section in second gear, but with people setting sections for clutch work it is best to have the low gearing in the first place.
