Hi,
i like the number ones on the seat unit,unfortunately they are the ones that it came with(sic) and the only real diffrence is that that they are thinner.As they are laquered in,it is a real pain (££££!!) to get them changed.At present,i have other things i want to do with the bike than spend money on adding 1" to the width of a number one.It will happen eventually though!!
