• I've just put a 19 tooth on the back for very hilly audaxing (just happen to live on / near Andy Corlass' turf) I've a double fixed on this bike, I've never had double fixed before.

    So here's my question. Most t'internet ramblings say that a 1 tooth difference is best. But as already mentioned I live somewhere hilly - however, I do like riding to the coast. So I reckon a 2 tooth difference would be better. Am I right or is two teeth difference too much and I'll regret it on my next coastal run?

    Currently have 48/17 and 48/19.

    Best for what? Last time I rode out to a hill climb, I found a 5 tooth difference (16/21) was best :-)
