Description

Description

The Shimano Ultegra HG800 road bike cassette is the largest in its kind with a 34T sprocket. The cassette has been given an improved finish quality to work better with a more fluent shifting motion and with a higher level of durability than its predecessor. These lighter gears make the HG-800 ideal for use on longer climbs.

Good workmanship
This cassette has a slightly better finish to ensure smooth shifting and durability. With its light toothing, the HG-800 is the ideal cassette on longer climbs while you hardly lose anything on straights.

Cassette's width:
This cassette is smaller than other 11-speed cassettes: it’s as wide as a 10-speed cassette. To mount it to your bike, a 1,85 mm wide spacer is included.

This cassette fits:
- Ultegra R8000 long cage rear derailleur (RD-R8000 GS, RD-R8050 GS)
- 105 R7000 long cage rear derailleur (RD-R7000 GS)

5 / 5

Great item. Gets 11 speed cassette on 10 speed hub.

- Richard 29 December 2020

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.

5 / 5

Great product and great service

- Darren 16 December 2020

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

5 / 5

Good quality

- Greg 10 July 2020

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

Changes gear smoothely
great gear ratios for very steep hills
Doesn't say ultegra on lockring
