Reviews over the

Shimano Ultegra R8000

more than meets my expectations

Pros & Cons

Top quality product....and a great price compared to other companies

Pros & Cons

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.

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

By now no secret but this is an absolute top notch cassette at a decent price. Makes Durace totally obsolete as far as I am concerned.

Pros & Cons

Very good cassette, well layered

Great quality, fit and forget. Lovely quick shifts.

Pros & Cons

Good product

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

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

Shifting gears goes very well

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

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

Pros & Cons

Fast delivery and clear information on the website

Pros & Cons

Shimano quality. Great service from Mantel.

Great cassette, good price.

Pros & Cons

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.

Pros & Cons

Usual Ultegra quality at a fair price

Pros & Cons

Price / quality as it should be

Pros & Cons

Please urge to deal with such a streamlined service, kept informed every step of the way from order to shipment to expected delivery time

Pros & Cons

Fast shipping. Cheaper and original. Perfect

It does what it says on the tin. Usual shimano quality great price and quick delivery!

Excellent products. Ultegra is a solid and performing line.

Pros & Cons

Meets fine, switching perfect

Pros & Cons

Good quality component and good delivery from Mantel, receiving it promptly and offering the best price around

The ultegra 11-32 cassette is fantastic quality, fairly light weight with crisp smooth shifting. Excellent. Mantel was the best price I could find online too and delivered quickly.

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

nothing to criticize: good product that fully meets the description and fast delivery.

obtained exactly what I expected

Pros & Cons

Good choice for my winter bike . Quality Shimano product. Kept well informed throughout the order/dispatch/delivery process.

Pros & Cons

Easy to install and works a charm

Pros & Cons

Quality product, delivery time and delivery.

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

This cassette has highest cost performance value, recommended.

Pros & Cons

Good prices on the website and fast delivery from abroad. Accurate order tracking

shifts well, runs nicely

Pros & Cons

My bike has Shimano 6800 group. The cassette R8000 11 speed shifts like a train.

Perfect, exactly what I expected.

Prima product rij er al jaren mee en als je je fiets goed onderhoud kun je 2 kettingen met 1 cassete gebruiken

Pros & Cons

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

Pros & Cons

Almost always have stock to deliver immediately.

Pros & Cons

The right compromise to have a reliable and versatile product at a competitive price.Excellent ratio scale ,you will definitely find the most suitable one for each competition.

Pros & Cons

The product corresponds perfectly to my expectations.

Whilst it is undoubtedly good quality, it is still too expensive in my opinion. Mantel with the best price around though.

Pros & Cons

Fine lasts for 8000 km

Pros & Cons

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!

Pros & Cons

Everything perfect original packaging and arrived in a timely manner. Very happy with the purchase.

Pros & Cons

By far the cheapest price I could find for the r8000 cassette

Pros & Cons

As pictured,original spare part and arrived very fast

Pros & Cons

quiet and smooth shifting

Pros & Cons

Familiar for years.

Pros & Cons

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

Bought for my home trainer. Excellent product, same as on my bike.

Quick delivery good price great communication would buy again Thank You.

Utilizzo da diverso tempo questa cassetta pignoni, mai avuto problemi.. Cambiate perfette e acquistato ad un prezzo ottimo Mantel sempre

Pros & Cons

Best price/performance

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

Upgraded from 11-28 to 11-30...was struggling with some hills. Notable improvement, extra spacing between gears not an issue.

Pros & Cons

top

The site is very user-friendly, the order is correct, the products are of high quality and the prices are reasonable.

Pros & Cons

Nice and light.

Pros & Cons

Not much to say, as light as you can get from Shimano, does what it says in the tin but a bit expensive for what you get

Pros & Cons

Does exactly what I expected and hoped for from it. Is the second cassette I install after a year and a half. Price quality guaranteed with this shimano Ultegra.

Pros & Cons

It is a high quality cassette at an unbeatable price.

Pros & Cons

Good switching Good price ratio

As to be expected with Shimano Ultegra, good quality cassette for tjr price. Nice clean, crisp shifting.

Everything is great! And fast

Meets expectations
