1x10 drivetrain against 1x11 drivetrain on mountain bike What are the advantages/disadvantages apart from the obvious loss of one gear in the middle somewhere if both drivetrains start and end on the same size cogs
You get an extra gear ratio and closer spacing of ratios with 11 speeds. 10 speeds drivetrains weigh 1 sprocket less I guess, and 10 speeds chains and cassettes are cheaper too.
