MBroady-
I thought the alu ones were generally noisier and actually wore quicker? I've never bothered with them - they tend to be for slow people who'd rather colour match their components than train. #generalec1collectivegraphicdesignertypeburn

Any reason to use something other than Shimano jockey wheels in a di2 derailer?
Are there any smoother or more durable options out there before I shell out on Shimano parts?
