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.

Pros & Cons

Actually makes Dura Ace obsolete
Price is not so bad
