I bought a R8000 big
"I bought a R8000 big 11 speed chain as the new crankset costs about $365. 00. I live in a hilly area so a compact crank 50/34 is best. Add a 11/28 cassette and the set up is complete. I did Ironman France Nice on this set up in 2012. Vingegaard for the Tour de France final week should have used a 12 speed 50/34 compact crank with a 11/34 cassette."
