Quality component, you get what you pay for
Really happy with both the quality and price of this component. I bought the chain/cassette bundle which meNt that I was getting the most compatible components. Great delivery, 2 days to Ireland.

You think you don't need one but what a difference.
Ive ridden my bike far mire tgan usual during lockdiwn, 6000km in 3 minths, so i thought i should invest ina new cassette even though the old one was only 8 months old. I added a new chain two as i replace a chain ever 2 to 3 months. Wow, whar a difference. Shifting is properly crisp and smooth.

très bien
I use this 11-30 cassette with 52-36 at front and Di2 RD 8050 SS. I'm sure that the Gear Position Control witch prevents to shift into the 2 smallest sprockets allows calculate the chain capacity of RD like: 52-36 + 30-13 = 33 (the chain capacity of RD SS)

Good value for money
Especially in combination with a new chain, a very affordable cassette! Did 7,500km with my previous cassette (also ultegra) without replacing the chain. Will replace my chain a little earlier this time though, then the cassette should definitely last even longer!

Good material.11-32 is ideal in combination with a (semi-)compact for hiking in the mountains.
Fast and correct delivery. 11-32 cassette from shimano in combination with a (semi-)compact is an ideal gearing for cycling in the mountains. A 32 is just right to keep pedaling smoothly at all times.

Wanted a cassette that makes the hills in North Wales easier to climb and this certainly does.
Living in an area where steep hills make cycling more challenging, I wanted a cassette that was easier on the hills. This 11 speed 11-34 made a huge difference, giving me that extra gear.

Smooth as silk with an extra gear when things get tough
Replaced my 11/28 cassette with this 11/32 and it’s given me that extra gear I needed to grab on the climbs. Great shimano quality as expected and a great service during lockdown

Outstanding performance
I have used ultegra cassettes for many years and I know for their durability many pro teams and riders use them as they are bombproof.

Fantastic product & fast service from Mantel
Gives you all the range you need when the road points up. Super smooth shifts and no need to be riding around with a 28 as the largest sprocket anymore. If you have standard Ultegra r8000 rear derailleur that should be fine, just new chain only.

Excellent climbing cassette
I'm not a cadence orthodox but still find the 2-teeth grading very smooth for climbing (I did some 20%+ gradients on my semi-compact) and descents. Though I did very litte flats b/c I intend to use it solely for the mountains. Still good piece of specialist kit.
Pros & Cons
5 / 5
Stops my legs exploding
I’m reasonably fit but don’t generate much power. Any sustained climbing over 7% burns me out leaving me wrecked on long runs. This cassette fixes that problem.

Excellent quality product as expected from Shimano
It's a cassette! It does exactly what it says on the tin. The range 11 to 30 is great. You might miss a ratio in the middle but it gives everything you should need at both ends of the spectrum.
Pros & Cons

Fits the bill... for the toughest of climbs
I purchased the 11-34 Ultegra R8000 cassette from Mantel to replace my current Ultegra 11-32 cassette. Good service and quick delivery. I do a fair bit of hill climbing and as I get older, I needed a little more help. I was concerned at first thinking that the gear ratios may be difficult to get use to. To be fair it is brilliant I love the ratios - the 30 tooth gear is ideal for most hills, saving the 34 tooth ratio for that really tough climb, or when I'm fading!
