It realy is anoying if ones new Campy isn't running smothly.
But I would never use these gear combinations though...
Using the small ring in front and the smallest sprockets
will result in "crossed" chainline where the chain might
possibly touch both the large chain ring and the front mech.
Shift up to 53/14 - and enjoy that - if necessarry
- you can shift down both front and rear without messing the chain.
That is often not the case on the S-word drive train!
