How long will a Dura Ace 10-speed cassette last in terms of mileage? What about Ultegra? Thanks in advance.?

Answer 1

Well maintained they can last a while but the chain will normally be the first to show ware.

Answer 2

Its difficult to determine the mileage you'd get since the way you ride and maintain your bike has a ton to do with component longevity.

I CAN tell you, however, that I get about double the mileage from an Ultegra cassette versus Dura Ace... and I am pretty much a stickler for maintenance.
