Pros & Cons

Pros & Cons

  • Great shifting performance, high shifting speed and smooth shifting even when you're standing on the pedals.
  • This cassette contributes to 1/3 of the gear shifting speed compared to the 11 speed Shimano groupset.
  • The sweet spot between the 6th, 7th and 8th sprockets has been taken into consideration while developing this cassette.
  • Compared to the Shimano Dura Ace R9200 12 speed cassette, you compromise somewhat on durability and weight.

Indispensable for more serious climbing .

- Frank 25 July 2022

The mountain version of the 30 - 11. For anyone who does not want to ride on the lightest or second lightest gear on steeper climbs. If you only ride in the Netherlands you don't need it, or indeed, you are better off with the 30 - 11.
