Funny story; This was actually shipped to a customer from a legit distributor as part of a set... with a mismatching non-drive arm. oof. He didn't notice for years.
Campagnolo Record 11 Speed Drive Side Crank Arm. 172.5 length. 130 BCD.
Who knows... maybe you crashed. Maybe you debonded the carbon sleeve. Maybe you just lost it. or maybe you're the person who got the other set of mis-matched cranks.
Either way...sometimes, you just need one damn crank arm.
Here it is.
