I have two, one for Barcelona one for france. I bought the second because I like the dust so much. The newer one I've upgraded to di2 and got some fab wheels, but in terms of comfort they are outstanding I feel tired after a long ride but never sore. In terms of speed I've done two sportives this year and won my age category in both, and that's not down to me! Next weekend I've got a big one, in perhaps the best cycling area in Europe,
