All The Talk At The Tour

[Razors Edge ★]

... about the descents well over 100kph (62+mph) really drives me nuts.  I'm not saying they can't or don't punch past 60mph (considering I can punch through 50mph), but you really can see how rare that ought to be even with the aid of a tailwind and a double digit assist from a steep downhill and monster gearing.  Long story short - pedaling at a VERY quick 120 rpm, using a relatively rare 55 tooth big ring AND a relatively rare 10 tooth cassette, you can expect to spin out at 52 mph.  To find an additional 10 mph - ie break 100kph - you have to have a helluva long straight stretch and it needs to be steep.
