Kim Kirchen quote

[willy]

?I had good legs on the Mur and rode the wheel of (Davide) Rebellin up the
climb,? said Kirchen, who became the first Luxembourg rider to win Fl?che. ?I
used a 53x21, maybe it was a little too big, but when you have Cunego behind for
a possible sprint, you need it.?

HOw do these guys do it? I thought parts of the last climb were at nearly 20% and he's climbing on a 53x21!!!!!!!!!

I tried that on Tiekkiesdraai recently and besides my cadence being only 20 I felt like I was giving birth.
