Hmm, I was very much on my own once I decided I didn't agree with what had been recommended as my size. I always suspected the 500L may be too long but Andy B seemed so sure it would be right that I went for it.
On the brochure though a nomad that looks a bit smaller than mine (shorter tt) would be ok for me, yet mine is "too small". Yet I think there are lots of happy customers who have been fine with Thorn's sizing advice. It has a bit on the Nomad leaflet I think about women liking shorter top tubes.
I was advised to raise the bars to get the bars closer. I tried this, but I prefer them at about saddle height.
