[MENTION=46029]fender1[/MENTION], you call it banal after telling us what a marvelous difference good tires and proper inflation makes. So uh you're joking, right? It's actually one of the consequential equipment choices among many choices that are far less consequential such as headsets and derailleurs and whatever else. In fact, in my view, tires matter more than frames except that frames are expensive and much harder to replace than tires which brings frames back up the scale of consequentiality, if that's a word.

[MENTION=391744]catgita[/MENTION], could you please share your chart with us? It sounds very useful.

I don't agree if these new articles impart nothing new. It's the first time I've seen rider-to-bike friction mentioned as part of the equation, though maybe it was implied earlier.
