Great product and bought as a replacement. Been using DA cassettes for a while and have never had issues. Great price and super fast shipping!

Avoid at all cost

Having had two of these fail due to unbelievably bad design, avoid at all cost. The top 5 gears are held together by pins which are simply not up to the job. There is a reason why Wiggins rode Ultegra cassettes.


Does not compare with Campy or SRAM. Specifically, rubbish plastic core in the high gear, softer metal. Although QUIETER, it is more UNDERPERFORMANT via resonance, vibration and ELASTIC FLEX. YES, the cogs FLEX. Critical elements in a 21st C cassette design, we are not 1960s cyclists anymore. Shimano went thinner, 11-12 speeds now, and worse tech. The difference between this and SRAM 1190 is a staggering 0.5 km/hr less, perceptible. If riding 11t-14t the difference is smaller but the time is lost in transition and friction with the chain, as well as the elastic deficiency of this "light' cassette. When going from this to SRAM, or Campy, for example, the feel is as if pushing another bicycle altogether, these works well with a good rear hub. Again, thousands of kms and these are better for ... recreational riders whom cannot tell nor sense anything above 30km/hr.

Quality and Service

The product arrived in excellent condition and was just what I needed. The Dura Ace cassette is super smooth in the shifts. There is nothing better than the Shimano DuraAce components on the market. The life of the components is remarkable.

Great option

Thank you Shimano for finally offer a wider range at the Dura ace level, this cassette with the 30 tooth option, offers a peace of mind satisfaction for the days one comes across a larger than anticipated 'lump' in the road, or one is having an 'off day', but the cassette does not have the weight penalty of Ultegra.

Dura Ace cassette

New dura ace cassette excellent piece. Works great no adjustments from the other cassette. Great service arrived ahead of time.


Dear friends The only thing I can say at the moment That I am pleased with the purchase, GROUPSET DURA ACE 9100. About the quality, I can only say when will test In the work set drive

Dura Ace R9100 11-30 cassette

I'm not a great climber but this cassette helps me become better. When compared to an 11-28 there is not much difference until you go to that last gear and find yourself in a rhythm and before you know it the climb is done.
