I will gladly buy again

- Lovis, 21 June, 2024

I had a 105 cassette again in the meantime and then went back to the Ultegra and I don't know if it's a mistake, but I think the shifting performance is better. The fact that the cassette is not shiny is also a plus point for me. All in all a solid finish!

The 34 is ideal for the steepest climbs.

- Erwin, 24 May, 2024

The spring classic Tecklenburg Rundfahrt is early in the season, when the condition is not yet optimal, especially after such a wet winter. The 34 is then ideal on the steepest sections, making you less broken and better able to continue the race.

Pros & Cons

Ideal 34

Coming from a 12/25 to this 11/30. Missed a few intermediate teeth at first, but oh how wonderfully smoothly you pedal up a hill or mountain. Bought for the mt ventoux. Will definitely succeed with this cassette and preserving the knees. Definitely recommended if you are going for something other than the flat Netherlands.

- Laurent., 5 October, 2022

Hello, I bought this cassette because the start was in 14 teeth, so I mixed the sprockets with the one I had to make a spread of 14 to 34 and 50 to the front and therefore the ratio suits me impeccably, for my 1.85 and 95 kg to walk.

- Luis, 11 February, 2022

Expected. A 34-11 gearing like this is for climbing hard mountains and long climbs (Alp d'Huez, the Lakes, Angliru...). If you are a normal mountain climber, a 32 or 30 is better. With this one you will lack the sprockets to ride or to climb 7-10% climbs at a good pace.
