Hi all, I recently acquired this front derailleur and shifters, but have been unable to identify what group they belong to. They were fitted to a Concorde Aelle frame, which also sported a Campag Avanti rear mech. The shape of the front mech is similar to a 980, but it has a shield logo on the cage, and no markings on the clamp. The shape of the shifters is similar to Triomphe, but there are no markings other than a '5' on the underside near the cable exit. Any ideas?
