Hi Guys,
After some help here.
Just fitted a Dura-Ace 9000 front mech to a 2008 Pinarello.
Front mech fitted as low as I dare to clear the big chainrings teeth.
When on the little chainring and the smallest three sporckets, the chain actually contacts and slides over the horizontal plate at the back of the mech.
Never seen this problem before.
I'm pressuming this older frame has a BB quite high in relation to the rear axle and the frame also doesn't like the new design 11 speed gear.
Any thoughts guys?
Thanks,
Pat.
