is it possible to use Shimano 11 speed road shifter with 10 speed hub/cassette?

if yes, how?

I have a set of Shimano Hydraulic 11 speed shifters but I don't want to upgrade hub to 11 speed. Is it possible to use the shifters in some way? Checking online on compatibility I realized that pull in shifting is quite different between 10 and 11 simano road.

Thanks in advance!

  • What number of speeds is the derailleur? – Argenti Apparatus Dec 4 '17 at 20:36

    I think you are gong to have to choose between the wheel and the shifters. I don't think there is a way to combine shifters and derailleurs/cassettes of different speeds – Argenti Apparatus Dec 4 '17 at 20:49

    If the hub is newer it might be compatible with 11 speed cassettes. To check, remove the cassette and see if a ~3mm spacer sits beneath the cassette. If there is remove it to have an 11-speed hub. If there's no spacer the hub isn't 11-speed compatible. – Carel Dec 5 '17 at 21:02

    Is it possible to change the freehub on the wheel to an 11-speed-compatible freehub? Note several manufacturers support this, including DT Swiss. – Tim D Dec 11 '17 at 14:12

    Note: Shimano 11spd Ultegra 11T - 34T cassettes dish the largest cog to work with a 10 spd cassette (same as their 11spd mountain cassettes) – Paul H Feb 27 '19 at 16:29

It is possible to use MTB 11 speed cassette on a 8-9-10 speed freehub body. Although not officially compatible, the recently introduced 105 derailleur RD-R7000-GS can physically shift up to 42t cog, but Shimano introduced also a 11-34 11-speed cassette which fits 10-speed freehub body, so there's plenty to choose from in 2019.

  • I will look into the 105 derailleur you mention. It seems like a good solution. I was checking it, but yes, they do not say that it can go up to 42. In many cases even 36 is a reasonable cog. – Paolo Goatspeed Feb 28 '19 at 12:09
  • Hey OndrejP, I actually can find the 105 derailleur RD-R7000 on ly in 11 speed, have you seen it anywhere for 10? – Paolo Goatspeed Mar 3 '19 at 11:39

    Paolo: R7000 is 11 speed, but I am using 11s shifters, 11s RD-R7000 and 10s cassette and it works perfectly fine. – OndrejP_SK Mar 5 '19 at 13:51
  • Ah, I had a feelig thatbthisnis what you meant and here it is. Cool. Thanks – Paolo Goatspeed Mar 6 '19 at 23:25

    Paolo: I have 11sp shifters and 11s mech. These parts can't be mixed between 10s and 11s (except Tiagra 4700). Regarding the 10s cassette I was just curious if it will work as a transition from 10s shifters+cassette towards 11s shifters+cassette, and it turns out it really does work. After initial setup I didn't have to adjust it. – OndrejP_SK Mar 9 '19 at 0:17

This question has been widely discussed elsewhere, including on Lennard Zinn's Technical FAQ blog.

A method involving removing one cog from an 11-speed cassette and setting the rear derailleur limit screws appropriately is described here. I am planning to do exactly this on a touring wheel built with a Shimano M765 mountain hub.

  • This is the right answer but should be expanded upon beyond a link. – Nathan Knutson Dec 11 '17 at 20:12
  • What would be the benefit in so doing and who would it accrue to? – Tim D Dec 11 '17 at 20:54

    Kind of the idea with SE is for the answers to not be dependent on outside links staying around, and have the info be there in the answer in full. Usually answers that do that well are what tend to get upvoted etc. Not that it's not helpful to give someone the link they need to figure out their predicament. – Nathan Knutson Dec 12 '17 at 0:10

    Understood. The problem of 10/11 speed compatibility will be around for some time, so hopefully those links will persist as they will remain relevant. – Tim D Dec 12 '17 at 16:16
  • I appreciate the answers. I know the topic and I am actually quite informed about the links you have posted Tim. On the other hand, the reason why I write questions on SE is precisely what Nathan is trying to explain: the internet is a wide source, often things are difficult to find. As well I know that among who answers to the questions there are very knowledgeable people. Those are the people who I had this question intended for. – Paolo Goatspeed Dec 12 '17 at 17:48

I think it wouldn't work in a satisfying way. Not sure if the spaces of a 10 speed and an 11 speed cassette are equal, but even if, at least you lose your "lower boundary" which is never a good idea cause it might happen that you accidentally shift too low

    didn't know that that works indeed by removing one cog as mentioned above. so sorry for the wrong answer! – madn Dec 12 '17 at 12:17
