I have 24 speeds on my bike.
I usually roll around with 2-6 or 2-7 settings.
Are you guys saying I should bump that up to 2-8, or shift to something like 3-4?
(sorry I have no idea how to write about gears in proper cycling nomenclature)
I got 28c tires now and I DO pant like I'm dying. I don't understand the phrase "commuting is not a race"
Use the number of teeth, front (chainring) x back (cassette). For example, on my standard road bike set up, I have 53t and 39t chainring up front and 12-25 cassette in back. So, my biggest gear is 53x12, my smallest gear is 39x25, and everything else in the middle. But I can guarantee you, you don't need bigger gears or skinnier tires so much as you need to learn how to spin the pedals faster.
