Get updated

ALEJANDRO - 10/03/2023

I had the short box, the one that came with the bike in 2018, with an 11-25! First it was the change of cassette for an 11-30 and now the longer box so that it goes smoother and I have achieved an unbeatable update!

Super price

Peterbike - 17/02/2023

Came very fast super well packaged at an unbeatable price congratulations I recommend

Shimano ultegra r8000 derailleur

Александр - 15/02/2023

Been waiting for this rear derailleur for a long time. Now I can put the cassette 11*32 and even 11*34. I am glad!)

Great product

jean-marc - 31/12/2022

This is the product I ordered Nothing extraordinary about it

Good product

Rafael - 31/12/2022

The best 11v derailleur in terms of quality/price and aesthetics... in terms of functionality, it's much better than the old R6800 series

Shimano ultegra derailleur

Iker - 10/12/2022

Very fast shipping and everything perfect, as always. Recommendable.

Purchase for a colleague

Miguel Angel - Bike-chollos - 06/09/2022

Joint purchase to an 11v cassette. Little can be said about Shimano. The product is the best there is for value for money... Bikeinn sent it on time and it was where I saw it cheaper when I bought it. I left it assembled and working correctly... my colleague was more satisfied than me because I did everything for him; -)

Upgrade from 105 to Ultegra

Horia Vasiliu - 12/12/2021

An absolutely excellent derailleur that is more refined than its predecessor.

Ultegra r8000 shadow gs 34t

jean louis Talet - 19/11/2021

first order on this site fast delivery. I have just received this derailleur I have not yet put it in place, but I can give my opinion on this model which I already use in short cage, the operation is perfect and precise however it is a little more difficult to remove the rear wheel pull the derailleur backwards while pushing it inward. Very nice Shimano product

Tiagra upgrade

Александр - 06/11/2020

Since the pull ratio of the Tiagra 4700 and all 11sk systems is the same, I simply replaced my Tiagra rear derailleur with this one. Works great.

Good stuff

sasha - 05/11/2020

Good upgrade compared to previously installed Tiagra.

Shimano ultegra

João Amaro - 25/07/2020

good gearing, ideal for not wanting to lose income going up I advise ...

Diverter

Zé Ricardo - 21/03/2020

Super happy with the product and the website in question.

Nice upgrade for 105 - keep 105 levers and frony

Robert - 11/02/2020

Brilliant upgrade...but get 80% of Ultegra's improved shifting, plus lower drive chain friction by just swapping rear mech. Ultegra levers are a purely cosmetic change, and front derailleur offers only a small functional improvement over 105, but the Ultegra rear derailleur upgrade is well worth the cost for serious cyclists. It also allows you to run a 11-34 cassette for serious climbing (although, even with 52/36 front, I've never really even needed the 32 rear). Jockey wheels run smoother than 105s, but if you're chasing marginal gain you can swap these for ceramic aftermarket ones.

Reception

Robert - 10/02/2020

Parcel received in perfect condition and on time.

Positive

Robert - 30/01/2020

For my first order on this site, no problem parcel received on time and in perfect condition.

Shimano

Sandro Paganelli de Souza - 15/01/2020

Perfect exchange, top product, I recommend it to everyone ...

Necessary for a change

Fernando - 09/12/2019

Excellent for switching to an 11-32 cassette.

Great product!

Yakub - 22/03/2019

Great shifting, low profile, will take up to a 34 cog, easy to fit and index.

Shimano ultegra 6800 electronic 11v

jorge - 03/01/2024

Is this pin compatible with the 11v electronic Ultegra RD 6800?

Answer of ANTONIO

This change is mechanical, not electrical. It is not compatible

Cassette 30

alvaro - 31/10/2023

Hello, I have an 11 30 cassette, Ultegra, is it better to ride for short or long? And is this product new? I mean it's not repaired or anything like that, thank you very much.

Answer of ANTONIO

I would mount with a long leg since you always have the possibility of mounting a 32 or 34 sprocket. The product is new

Answer of ALBERTO

The short one is suitable for a maximum of 30 and the product arrived new, make sure you buy the version that you need clamped to the tube or welded

Answer of EGAS

This derailleur is new and allows cassettes of up to 34 teeth, that is, it is box or long leg. On your 11-30 cassette it will work perfectly.

Compatible con di2

José Manuel Pintado - 07/10/2023

This component is compatible with R8000 Di2 or if not, what would it be. All the best

Answer of ANTONIO

This change is mechanical and not electrical.

Answer of EGAS

It is not compatible. The only compatibility of the R8000 Di2 is with the brake calipers.

IS IT 11V? IS IT LONG LEG?

Answer of bruno

yes it is an 11 speed with long cage that can work with an 11x32 cassette for example

Answer of Carlos Enrique

That´s right, 11 speed and long leg.

The R8000 RD is 11 speed. The medium cage can take up to 34T. And no, this is the medium leg, not long leg.

Answer of Eduardo

Yes correct 11 v and medium box pin

Yes, cassettes 28 to 34

Compatibility

Raúl - 30/10/2022

Hello, I have the 10V Ultegra 6700 groupset mounted, that model seems to be discontinued and mine has to be replaced due to breakage, could I mount this R8000 rear derailleur? Thanks in advance.

Answer of Adolfo

You don´t have to look for a change for 10v this is for 11v, keep looking there will be some in 10v.

Doubt

Maximiliano - 28/10/2022

Hello!!! I have a couple of doubts, the leg is short? It is for 11 or 10v because it appears to me at the beginning that it is 11v but in the description it says that it is 10v and the last one is for an 11-28 sprocket? Cheers!!

Answer of Adolfo

Not the short or long leg is that it can mount larger cassettes up to 32 teeth or maybe even more, for that development with a short leg it works well, but what you have to look carefully is that it is for the speeds that you have mounted that is essential or 10v or 11v.

Doubt about this product

Cleber - 05/09/2022

Hello, I would like to know if this product is for 11 speeds or 10, since in the description it says 19 speeds, but when I choose it, it gives me doubts. Greetings

Answer of Adolfo

The gearbox I bought was 11-speed. In the description, it is true that it is confusing, but you have to choose the speed range that interests you.

Change r8000

Sebastián - 30/05/2022

Hello, can I use it for 10v? The one I have has a short leg and I want it so I can put a 10v 11/32 cassette on it. Cheers

Answer of Adolfo

Having the same range of speeds yes, what you cannot do is mix components of different speeds if it is 10v then everything in 10v. (Chain, chainrings, controls and cassette).

Ss or gs

Nando - 06/05/2022
