Hi to you all,I have come back public rather than a PM to(thank you for your rapid reply)fatfixie.I doubt that they are Christophe,unless they are pre 60's(before my time of serious traffic dodging).
I ride Christophe on two bikes both with Marcel Berthet Lyotard Platform Pedals fitted,the bikes are modern,a 10yr old Bianchi & a 2009 Claud Butler Levante.The Christophe Clips are named across the sprung front web just below the strap locator.
PS.These pedals have to be the finest/most efficient to gain rapid access to especially on fixed wheel,I know,I was one of those traffic light stand still artists. Why fix something that ain't busted?.
Happy & Safe Riding to You All.
