Reviews over the

Shimano Ultegra HG-800 11 speed

I would not have thought that the 11 to 34 sprocket on ultegra runs so wonderfully

Purchased as a kit with Ultegra derailleur and chain. Don't forget to fit the spacer washer before fitting the first sprockets on the freewheel body.

Perfect, hard to find on the net these sprocket boxes. Great price as well.

Thanks to the 34x34, it's impossible to get stuck, and there's always a gear to turn your legs. The cassette has fewer holes at the top than the 11-32: 34-30-27-25-23 versus 32-28-25-22. You can keep the plate up to 27 with a good chain line for false flats. I keep the same chain length as with an 11-28 for racing, just adjust the derailleur tension screw. You just sacrifice the 12 and 14 teeth, which isn't a problem going downhill.

Pros & Cons

bought to compose a cassette special mountain with a 11x 28 to make a 14 x 34 well staged associated with a GRX 46 x 30 I can now make all the climbs with the train without asking me questions. I am an amateur of 54 years 1,92 cm 82 kg. cassette super reactive and fluid. 2 cassettes to make one is very expensive! Mr Shimano retail sprockets please! PS: rear derailleur medium clevis mandatory Bonne route

Shimano cassette = top

Pros & Cons

Makes the difficulty easier when the gradients become become significant.

Pros & Cons

Unbeatable value for money, like the entire Ultegra range. Good spacing in 11/34

Price is right, quality and function is good, what more could you want...

I have a few high quality 10 speed wheels and this cassette unlocks them for use on 11 speed setup. Not really for racing but great for general usage.

I bought this to put a cassette on my indoor trainer to match my main bike. Usual Shimano quality (great) and a great price and fast shipping by Mantel.

Pros & Cons

So far very pleased to move from 105 11-32 Ultegra 11-34. More versatility

Pros & Cons

Pros & Cons

Nothing to add.

Pros & Cons

Good product that also fits 10spd atb body. For me the steps at high gears are not nice. Have rebuilt the lower part of cassette with steps of 1 tooth per gear.

Pros & Cons

Great product, only downside is you spend more money than the other ratios available and the lockring doesn't say 'ultegra' on it. Its a tiny thing, and annoying. Let's be honest we all like to show it off.

Pros & Cons

good, slick gear changes, both single and multiple. As with all shimano kit this is good quality. Given 9 as nothing is perfect.
