djb...just found out what my gearing is on the bike...it's a surprise for me! I have, on the front, 30-40-50 for the chainrings and I have a 12 to 28 7speed cogset on the back. My wheels are 700*32 Panaracer Gravel Kings and my crank arms are 175mm. The cogset on the back hasn't been adjusted so it's a standard setup; I'm trying to find out what the cogs in between the high and the low are but not having much luck so far. I though my small chainring was a 26; honestly I don't think I've heard of a 30 tooth small chainring.
