Does anyone have any experience with the 11 speed shimano group brake calipers? The 5800 ones particularly are meant to accommodate larger tyres, but does anyone know if this is because of a longer drop or whether they've actually raised the 'bridge' bit. I'd really like to run 25c on my Argos but the smallest bit of road muck and they start to foul. I had mistakenly though 23mm rims would make the tyre run lower but it has had the opposite effect.
I know GP4000s size up large, are Pavé a bit more true to size?
