I'm thinking about going to from 8 speed Shimano 105 to 11 speed Shimano 105-5800.
I know I'll definitely have to change my cassette, chain, rear derailleur and my right shifter. But what about my crankset? My current chain is 3/32 inches wide and my new chain would have to be narrower so what if it doesn't fit on my crankset? Is that possible?
