That question and answer is from the American Classic website. I was on it earlier today researching a new 29er rim they're offering to consumers. Looks promising: 380 grams, 25mm wide, and a 600mm ERD--all for 99 bucks.
No one preaches like the converted. I too was once addicted to high tire pressure. I thought that the higher pressure meant a smaller contact patch and thus less road resistance. So I endured years of sore wrists and subpar braking and handling all in the pursuit of straight line speed. I used to buy Vredestein TriComp clinchers because they advertised a maximum inflation of 175 psi. I spat on the ground whenever anyone mentioned Michelins, as their max inflation was only 116 psi. Also, the skinnier the tire, the better. I was running nothing wider than a 700 x 23. I would use 20s if I could find them.
Once or twice a person tried to get through to me by forwarding an article about how lower pressures could actually offer lower rolling resistance. Whatever. What the hell does Sheldon Brown know? I was riding about 200+ miles per week (all commuting) so I wasn't about to test an idea that sounded illogical and that might add minutes to my commute by slowing me down.
But with age comes wisdom, sore joints, and product innovation. In 2007, HED released its Ardennes wheelset with the C2 rim profile. I paid attention because they're from Minnesota (as am I) and as a student of cycling tech history, I knew HED's reputation for pioneering ideas that were taken up by other manufacturers. The original tri-spoke was a HED design.
The C2 promised a tubular like experience by virtue of its wider rim bed, which changed the shape of the tire contact patch. Nothing over 100 psi was recommended, and nothing narrower than a 700 x 23. I guess I was ready to hear the message this time about tire pressure.
I ordered some rims once they became available and paired them with some White Industries hubs. Ever since, I haven't ridden over 100 psi on any clincher wheelset. I out roll, out handle, and out brake all the other fools who cling to their 19mm wide rims and 130 psi ways.
