Hi Richard,

I used 605s on my only bike (at the time) for over 20 years (the rest of the bike was an eclectic mix of Campy and Shimano DA parts). They served me perfectly well - with SM pads. More recently the bike had a complete Campy makeover so the 605 brakeset is now in the parts drawer.

The date code on the back of the 605s suggest that they are July 1980 which would fit nicely with when they were set-up for me.

They are not all that bad looking - but not as elegant as NR mainly due to the plastic covers on the quick-release lever, over the QR bolt, and on the centre bolt - not to mention the barrel adjustors.

I never got the right tool for adjusting them properly so was always fighting to get them properly centered.

Hope this helps.

Paul.

Paul Williams,
