I went for the gear reduction because I live in the South Wales valleys, and you can meet some very interesting hills here.
I went to Cardiff today to collect it, and have to say, it's been set up perfect. I have read that spoke tension is a little suspect on Brompton wheels , well not these, very very good, in fact all I have had to do is get my seat set correctly.
I rode it to Penarth over the Cardiff barrage, and went at an angle to go over a metal drain that was proud by about 15 mm, and it was wet, well my time doing trials riding on motor bikes stood me in good stead, oh and the railings or I would have been in the sea.
Yes, I think I will have some good days out on it.
