I just bought a 1977 R75/7 and need to replace the rear tire. The bike currently is shod with a good front Metzler ME77A (40% left) and a dead ME99A.
I've been reading good reviews on the Michelin Macadam 50.
What is the consequences of putting a 50 on the rear and running the 77 on the front? TIA
I can't speak for this pair or this bike exactly, but mixing tires comes down to riding to meet the less-aggressive tire.
I had a Michelin on the back but didn't like their short-lived front tire so used a Dunlop. I wasn't able to ride as aggressively with this setup but I got the longer life I was looking for.
(Michelin has redesigned their front tire since I last used it to be a little longer life but I haven't tried it.)
