Presumably the 650b x 47c version is with v brakes?
Mudguards are 51mm, so I'm pretty confident I can fit 47c tyres without guards using these calipers. V-brakes aren't really an option anyway, because they can't reach the 650b brake track.
What size is the frame?
Seat tube is 56cm centre to centre. Top tube 58cm centre to centre.
