Campagnolo Nuovo Record 68-SS -+1 – +1.5 Bottom Bracket / ENG

Campagnolo Bottom Bracket
Nuovo Record
Axle Marking “68-SS-120 +1 – +1.5”

Campagnolo added a little lip to the leading edge of the front derailleur in 1976, as the CPSC had ruled it, because too sharp and dangerous in a crash. These lip on the derailleur cage then made contact with the crankarm, so there was a slight groove made in the arm profile. To prevent that, a slightly wider spindle was made for the Nuovo Record Bottom Bracket. These spindles have the “+1 – +1.5” marking.
