Short and sweet
"Been using 165mm XT for years, now available in 160mm so I had to give them a try, the new look is very nice and more subtle than the XTR, 160mm length seem perfect, XT are my number one choice for cranks, I've got a works chainring in red which gives 52mm chainline like most aftermarket rings do so you don't have to run 55mm chainline with Shimano's new rings."
