Spotted on my commute home: A car with a rooftop bike rack (bikeless) and a sticker on the back with this simple message: 53x11
Seriously? 53x11? As in, 126.6 gear inches on a 700x23 tire? As in, 45mph at 120 rpm on that same 700x23? (Math courtesy of the late, great Sheldon Brown.)
Here's a tip: If you can turn it, you probably don't need to advertise it. Just sayin' is all.
(Slice of humble pie: I was struggling to turn over a 42x18 at the time. So what do I know?)
