Thanks for the replies.
I wonder what sort of freewheel they'd have on something like the Galibier...?
I have a 52/39 and 13/26 on my road bike and a few weeks ago did the Col de la Madone with a mate... think I could have done with that 28 T cog of Froomes..
(The Madone is a regular training run of Froomes, as it was for a certain Lance Armstrong, for those interested.)
