- "Stay off the big ring." Only use it when you have to. Easier more efficient pedalling I guess, I never asked why.
- "Rest in the drops." I think I heard that on TV in the 80’s from some cycling coach. It is a hard one to stick to sometimes. I think this is a really old piece of advice.
- "Air is cheaper than Kevlar." Never let your tyres drop below 100psi. Stops glass penetrating the tyre among other things.
People need to remember that you said a CRUSTY roadie. Being a crusty roadie, I can explain:
Why #1? Because on the flats, the gearing on the little ring is better able to help you fend off an attack.
Why #2? Because you only have brake levers in the drops.
Why #3? Because it's a myth. To keep stuff from penetrating your tires, decrease your air pressure. (It's a lesson I've learned the hard way. HUGE difference. Higher pressure means more flats from debris.)
