Thanks!
I simply disasembled the 533 sized bike. Sold the frame and purchased the 555 S frameset. Built it all back up in a day and rode it today. 25 miler but loads of stops for adjustments to gears, saddle position seatpost etc, but enjoyable.
I am supposed to have this one (well the one it replaced) as a Winter bike! But having two of them both of which are very nice the only edge to which is the better one, is the fact that the blue one has a Schmidt SON hub whereas the green one has a Shimano dynamo hub.
Mmm ........................must make some changes to the spec of the 'best' bike.
