I have a 2004 Jamis Aurora with a 52/42/30 triple and an 11-32 cassette in the back. 30x32 (25.3 gear inches) being the lowest gear is frustrating for the hilly terrain where I live (e.g., 7% grade average over several miles, with higher local…

Why doesn't "butt soreness" affect serious cyclists?

Over time, my seat (butt) has been broken in by my saddle. I don't have a callus, and nothing obvious has changed. Physiologically, why doesn't riding cause seat soreness anymore? On the flip-side, what does a saddle do to a less-experienced…

Do cassettes and chains need to be replaced at the same time?

Someone recently told me that if I replace my cassette I need to replace my chain (and vice versa) so that they wear evenly. Is this true? And, can anyone elaborate on the reasoning for this a bit more? Why is it important for them to wear…

Why are aluminum frames painted at all?

After reading about how complex is to paint a bicycle frame, I wonder, why is this done at all? Steel frame obviously needs painting as it may rust. Aluminum or say titanium does not rust in similar ways and the color is not much worse than black.…

Why should little kids not have back mirrors on their bicycles?

In a paper from the mid-1980s, there is a kind of PSA box listing some things that small children should NOT have on their bicycle. Most of them make sense, but there's one that confuses me: "back mirrors". Why is that bad? Isn't it a good thing if…
