Lightweight: Drivetrain Components

I replaced the Shimano Dura-Ace 11-28 cassette on my S-Works Roubaix with an 11-30 cassette for easier scaling of mountain roads. The extra gear certainly helps on long climbs.

Cons
  • Volume

rusts after 3 months of moderate use

bought this product in April and it started to rust after 3.5 months and 700km of running. These cassettes must not rust. Of course I missed the return window by a month. avoid!

Cons
  • There are nuances

It took me 30T so I could get my bike.

I needed a 30T so I could get my bike across the continental divide near Leadville, Colorado. This helped and works as expected with my old Dura Ace Triple components.

Cons
  • Long Delivery

What a difference 30t!

Nothing. What is the difference 30 teeth. I live in Southern California and it's very hilly. I'm a terrible hill climber and need all the help I can get. This cassette serves its purpose. It's also really cool - titanium and carbon and all that. Much cheaper than I expected with all its bling.

Cons
  • Nothing
