Waited a long time for them to manufacture an 11 speed Ultegra 11-30
5 / 5
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!
Pros & Cons
5 / 5
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
5 / 5
Good value

Just the job for the hills
That bottom gear does just the job on the 20% hills
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.
Pros & Cons
5 / 5
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.

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.

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.
Pros & Cons
5 / 5
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

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.

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)
5 / 5
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.

Great service from Mantel
Even though my bike has an Ultegra groupset, I normally use 105 cassettes as they are cheaper and only a few grams heavier, but with Mantel's competitive pricing I can get this for the same price as a 105 cassette from other suppliers.

Light engineered excellence
I’ve got 3 sets of ratios and they are all fantastically made & work very well on both mechanical Di2 bikes, if there’s was any fault is not being able to get quite the spread of gears I want as a close ratio set
Pros & Cons
5 / 5
Great value from Mantel
Bought this cassette along with a KMC chain as part of a deal. It’s a great idea as I usually change the chain and cassette at the same time. Well packaged , super speedy delivery and great communication as to the progress of my order. Many thanks

Pros & Cons

This is a good cassette
I do not understand why they sell so many bikes with the silly 11-30 cassettes - it just means that 11-12-13 sprockets are a waste of money since hardly anyone is strong enough to use them. 14-28 gives you far better range of gears and the one step change for most of the cogs works far better so you get exacty the right gear for the way your legs are feeling.

Great value & quality
Lovely quality cassette, very little difference to my last Dura ace unit, just slightly heavier and not quite as bling, the change from 11-28 to 11-30 has been great as the 11-21 block remains identical (11,12,13,14,15,17,19,21) and only the lower 3 gears being 1 or 2t different, great service and price from Mantel. Took about 3 days from ordering to been delivered by UPS (I'm UK based). Thanks

I purchased a Shimano Ultegra r8000 11-32 cassette. When looking for this item Mantel came up with the best price but I found their website to be great and once purchased the item arrived in an amazing package. I'll be using Mantel again soon and have told all my cyclist friends about them.

ultegra always works. all one needs
This 14 -28 ratio I am very occasional under geared but it is the most useful ratio with no unused or rarely used sprockets.

You don't need anything else.
Beautiful piece of engineering that will last a very long time if looked after. I have been using Shimano products for over 40 years and they are bullet proof.

It suits my ability
I find the individual gear changes more comfortable than, for example, the 11/32.
