OK, I'll pretend I'm speaking louder and slower.
Frank gets a one mile per hour increase in speed if he switches from a 44 to 46 chainring, if he's riding at the same cadence. And he
is riding about the same cadence, because he reported he gets about the same average speed with either chainring.
Just to set the facts straight, I don't know what my average speed was when I had the 42t chainring on the bike because I didn't have the computer at that time. I went to the 44t chainring to see if I felt faster with it. I put the computer on the bike and recorded the stated average speed. Now I think that I'll return to the 42t to see if there's any difference. I suspect that if I feel more comfortable with the smaller chainring it may compute to a slightly higher average speed. My higher cadence may more than compensate for difference of two less teeth.
