    30 x 25 and yes, if the climb's a real steep one (road bike).

    not sure on mtb but looks like about 26 x 28, but as mtb is heavier that the road bike it works out about the same in terms of work rate.

    Some hills are really steep and a granny gear is better than walking!!!!!!!!!!!!!!!!!!!!!

    For the last 4 zig-zags on the Galibier (after the tunnel entrance), on a fully loaded camping tourer, in the sleety rain after already doing the Izoard that morning?

    The answer is yes I did need it, thank you very much.

    I have been looking at the Dahon Jack ..It is a folding mountain bike and has a lowest gear of 37" and wonder if this is low enough

    Going up towards Ipsley Church from Pikes Pool (a hill to me), Arrow Valley Park, Redditch.
    I got overtaken by a bloody duck walking up the road !!

  11. 42X25 (I think) on my semi - roadie, 26X30 on my tourer. Although I find low gears are not really necessary when all you use your bikes for is hanging up in the shed.:ohmy:

    24*26 on the road bike for a 25" gear. A bit overkill even for the Alps, but I'd sooner have a lower gear than I actually need.
    I'd intended to go 26*26, but the LBS was out of 26T chainrings. My excuse and I'm sticking to it!

    I'd have thought the lowest you need is the one that keeps you moving just above stalling speed. So one for a bike, and a much lower one for a trike, where you can travel at much less than walking pace without falling over.

    I have no idea about numbers and stuff..

    42 x 25 or 42 x 23, depending on bike. Most of the hills round my way are short and steep or longer but not so steep. All are honking distance if necessary. If I was going to go up a cocking great mountain: 25 x 42.

    I've no idea what the lowest gear on my Brompton is. I put a littler chainring on it tho'.
