ShimanoDura-Ace CS-R9200 12-Speed Cassette(Return to Product Page)

Added this to my new SL8 build with Ultegra Di2 and really enjoying the 11-34 gearing vs the 11-30 I was/am running on my other wheel set. I do not notice the increased jumps, but notice the amount of time I am able to stay in the big ring without having to grind. It is Dura-Ace so it is hard to give it a 5 star review as a value, but BTD is always good value.

This 12-spd cassette works well with my Campy Super Record set- up and gives me another gear lower. And as l get older, my bikes seem to need it! It never gets easier; you just ride on, eh Greg?

And at BTD, the price is... doable.

Throw this on your back wheel and ascend climbs like a feather.

The new 12speed Shimano cassette is part of the updated groupset. Like all of the Dura Ace components it's well crafted and allows for smooth and efficient shifting.

As a person who climbs a LOT the 11-34 is perfect for both rolling hills and long sustained climbs, the weight is managed by balancing titanium cogs with aluminum, adding strength where needed and lightness in concert.

This 12 speed cassette is great for climbing the steep grades in the mountains where I ride.

Had an 11x30 of the same cassette but needed more lower gears for climbing. This is exactly what I needed. BTD matched my best price. Fast shipping. Perfect!

Light and does what it's supposed to so well, I forget about it on every ride

A great cassette that I have on a number of other bikes. Will buy again.

I will use it with my new DI2 set up when I get all the parts.
