It's darned close. If mine is higher, it's by the rim depth or less. No I'm intrigued. On another thread, a new Dahon with the different frame style, I think same RD as you, they have a 50/34 11-42, the gear range is fantastic, 566% if I recall, for heavy touring I might want over my 400%. But due to all the parts it would require, I would wait to put that investment into a disc bike.
