I'm curious how swapping the 40T chain ring for a 38T would effect the lowest gear. How much lower gear inches will I get from the replacement? Would it be worth it? Let's take a look.
I saw the preliminary gear chart and thought, "Why stop here?" So I decided to tap on another couple chain ring sizes to see how low I could go and what the effects would be on the high end Here's the side by side comparison of a 36T, 38T and 40T chain ring on the SRAM Dual Drive setup.
Tough choice. I love the idea of being able to go under 15GI's, but that comes at the expense of one less high gear than my stock setup. I'm liking the 38T chainring.
