Reviews over the

Shimano Ultegra R8000

Order perfectly compliant and delivered quickly.

Good value for money

Very satisfied with the service always delivered on time, usually the day after if not they keep you well informed.

Pros & Cons

obtained exactly what I expected

Pros & Cons

Fast shipping. Cheaper and original. Perfect

Very easy to assemble, as always with Shimano

Changed from a mountain cassette directly to this polder gear (11/25). It feels great, I can always ride with the right gear. Quality from Shimano is again top notch and delivery super. Swapping between cassettes is easy with the right tools. A good upgrade for riding and comfort.

Pros & Cons

Does what it is expected to do.

Pros & Cons

As ordered. 11-speed cassette for the mountains.

For my bdc use, in saluta it does its job perfect ratios.

Meet my expectations

Pros & Cons

Have been using this brand for years and have been very satisfied.

Pros & Cons

Ultegra is an insanely good group. This cassette is no exception. You never have to hesitate when you need something from Shimano.

Pros & Cons

An excellent cassette, 11 speeds at a reasonable price and unbeatable smoothness

Product purchased to replace a dura ace cassette. I am very satisfied

Good to know: the Shimano Ultegra R8000 11-32T cassette can (just) be used with Shimano's medium cage derailleur, whether mechanical or electronic.

11-speed cassette to replace an old one meets my expectations

Almost always have stock to deliver immediately.

Pros & Cons

Familiar for years.

Pros & Cons

Good quality and fast delivery as we have come to expect from Mantel.

Pros & Cons

The product corresponds perfectly to my expectations.

It meets my expectations. Easy to assemble and especially because of the guide that shimano put with it so you can actually never assemble the cassette incorrectly.

Pros & Cons

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.

Pros & Cons

Product fully meets expectations

Pros & Cons

Product conforms to my expectations, available, fast delivery and an unbeatable price.

Pros & Cons

Bjr I was impatiently waiting for this cassette and thanks to Mantel I was able to get it at a very good price. thank you Mantel

excellent price-product ratio

Pros & Cons

I tried the cassette today. No problem.

Pros & Cons

The longevity is of course also dependent on the chain care, but the cassette forgives much. Had them last 8 chain changes in use and it would be even more in it.

Pros & Cons

Combined with the DI2 system, fast, precise gear changes.

Pros & Cons

more than meets my expectations

Pros & Cons

Quickly ordered and neatly arranged

Pros & Cons

Yes, very good development, if you maintain your chain well, no worries, no noise! I use this development to punch in the bumps and small hills.

Pros & Cons

Before I used to ride an 11-32 and a friend suggested me that in Madrid for the posts that there are with an 11-30 I had enough, well after testing it thoroughly it has exceeded my expectations.

Pros & Cons

Great site for all occasions

Pros & Cons

Very good cassette, well layered

I've been using 11/28 and 11/25 for years. I use two a year

Pros & Cons

Top products,

Fast delivery, and reliable

Pros & Cons

It meets my expectations.

Pros & Cons

Cassette has good gear ratios, so shifts well

Pros & Cons

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.

works as expected

Pros & Cons

I have not mounted it yet but it looks very good.

Pros & Cons

Price / quality as it should be

Pros & Cons

Already had this one but was worn out, so attached and runs like a charm again

Pros & Cons

Everything perfect. Sprocket package arrived as requested and very quickly

A Shimano cassette runs well. Always perfect

Pros & Cons

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.

Pros & Cons

Think carefully in advance about what gear ratios you are going to need.

Pros & Cons

Great product from Shimano, easy to mount and does what it is supposed to do!

Pros & Cons

Meets expectations. Well packaged and easy to assemble.

Pros & Cons

Always satisfied when I order something from Mantel, fast delivery perfect website,

Pros & Cons

Excellent products. Ultegra is a solid and performing line.

Pros & Cons

the best price-quality cassette, although it is getting more expensive every day...

Pros & Cons

As always, very fast home delivery and immediate mounting. Super easy compatibility with my current Dura ace.

Pros & Cons

The answers provided by the MANTEL team enabled me to make a targeted purchase that met my needs.

Pros & Cons

As advertised, I recommend this product, very good quality.

Pros & Cons

If other online stores have no more goods, you should look at Mantel. It is best to look there. They have it 98%! Gold value nowadays.

Pros & Cons

Product I expected . Good price . Very fast shipping . I recommend this site Mantel .

Pros & Cons

It's just as useful in the lowlands as it is in the mountains, but the sprocket spacing takes some getting used to (compared to an 11-28 cassette, for example), but in the end it's perfectly acceptable.

Pros & Cons

Meets expectations

Pros & Cons

Item came to Germany within 4 days.

Pros & Cons

top

quiet and smooth shifting

Pros & Cons

Fine, will always choose this.

Pros & Cons

As long as Shimano Ultegra has been on the market, I have never used any other brand. Strong and hard-wearing cassettes.

Pros & Cons

A Shimano product, therefore very reliable, with an 11/30 gear ratio that allows it to go everywhere.

Pros & Cons

Top product.

Pros & Cons

Bought the 11-30 options downgrading from a 11-28 Dura Ace R9100. The shifting petformance is comparable to Dura Ace or better, there is less noise overall. The 30-teeth sprocket is a benefit on 10%+ gradients and worthwhile the extra weight. Service was superb as usual. Prompt delivery of a competitively priced item that was not available everywhere.

Pros & Cons

serious and well-priced+++++

Pros & Cons

Having to look for a crucial part for your bike last-minute is never pleasant. Thanks to Mantel's lightning-fast service, I had my new cassette delivered to my home a day later.

Pros & Cons

price of the cassette less expensive ,delivery in 24 H and free,very good seller ,thank you to you

Product meets my expectations

Pros & Cons

Compliant product not available in France for several weeks.

Pros & Cons

Product received very quickly and quality product The combined offer is one you won't find anywhere else, and it's really top-notch.

Pros & Cons

Nothing but praise for the handling of my order. I was kept correctly informed of the delivery time. These times it is extremely difficult for suppliers to get the right products but Mantel takes very good care of its customers. Thank you very much for this.

First time I've bought from this site, I highly recommend it! Unbeatable price, availability whereas Shimano parts are complicated at the moment... top delivery in 2-3 days. Nothing to complain about, I'd recommend this site without hesitation!

Pros & Cons

Very positive

Pros & Cons

quality product received at a great price and in a tight time frame

The 14/28 is ideal for long touring on the flat or time trials where the smallest cogs are never used for sprinting, that way you have a lot of gears left in small increments so you can always ride a nice cadence. 12/25 is perhaps a little lighter for the powerhouses among us who also want gears that are close together. By the way, for quick cleaning, the coating on the 105 is nicer, it is smoother.

Pros & Cons

11 speed cassette is used on a SPEED PEDELEC with rear wheel motor. The ratios are excellent, always a cadence to match the speed. Durability has yet to be experienced.

Pros & Cons

Meets fine, switching perfect

Pros & Cons

Good experience mer this product,switches smoothly.

Pros & Cons

Meets my expectations

Original Shimano ultegra cassette at a competitive price. Fast delivery.

Pros & Cons

Great stuff in combo price with chain included
