I'm planning on riding the 'Nibberittet' again this summer, but this time fixed!
The course winds up the side of a mountain overlooking Gieranger fjord. Its basically 0 - 1500 (meters over sea) over 21 km. I make this a 7.1% average gradient.
I was thinking about running a 42:22 gear, which gives me just over 50 gear inches. This should be a decent gear for most of the climb, but might lead to too much lactic acid build up in the later stages (not spinny enough?). TBH I just guessing. I am somewhat limited by the 144BCD of my campy chainset, so cannot go any lower than 41/42 teeth up front.
Anybody with any thoughts on this?
Any experianced climbers with advice?
(NB: there are buses with space for bikes for the decent)
