So one could use the now available sora 3x9 shifters on mtb/trekking front and back derailleurs? Just wondering because I would like to change the handlebar on my trekking bike for a road one, then I need to change the shifters too. So far have no info that can be done.

@@willemrm4033 yes to my understanding the Sora 9-speed shifter and derailleur are compatible with any other Shimano 9 speed (road or mountain) parts. I do not know on the front mech, but Sora is easy in such a way that it actually provides both road and MTB 9 and 3 speed shifters. blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/ here is the only exception to this and some more explanations www.bikeradar.com/advice/buyers-guides/a-complete-guide-to-rear-derailleurs/#:~:text=Shimano%20derailleur%20compatibility,road%20shifters%20or%20vice%20versa. "Shimano derailleur compatibility Most 8- and 9-speed Shimano mountain bike and road kit is inter-compatible because they both use the same cable pull ratio. This means that you can use an 8 -or 9-speed mountain bike derailleur with road shifters or vice versa. The only exception is pre-1997 9-speed Dura-Ace gearing, which won’t play nicely with anything because it uses a totally different cable pull ratio. "

@@innocentiuslacrim2290 Thanks very much, front derailleur would have to remain an MTB one I suppose, as the Sora - or the 105 - triple one are meant for 50-39-30 blades if i'm right. that must be rather problematic on the 44-32-22 Alivio T4010 cranks. If i decide to go through with it and things work out fine , i'll let you know.

S9 can i use Alivio rd with sora shifters (sti)

men id like to know too, if sora sti shifter will work with alivio rd? planning to convert my straight hb to dropbar

I already tried it with 42t. But you need to replace the B screw with a longer one

Don't think so, pull ratios are probably different

Would stick with an mtb derailleur on mtb personally. Derailleurs don't often go wrong, they tend to just move as much as lever tells them to. Might be something other than derailleur causing issues

I think all MTB and road 9 speed can mix and match. No idea if the road bike is a good buy or not. Not many road bikes tend to come with Deore kit, flat bar and 1x.

I'm not sure of the technicalities behind why but it is the difference between indexing correctly or not. Try both ways when you try the conversion. See if you can get indexing correct with routing as per instructions. I couldn't!

@@user-bi9tn4mz8i thanks for the response and for putting the video up!

@@kwengca 👍 let me know how you get on with your set up

looks like the angle has changed slightly, and due to that it's pulling on the derailleur just slightly more for each click of the shifter.

Today I was doing a pretty similar conversion (9s road shifter but Alivio 9s hanger). Shifting was good on the highest cogs but I struggled to tune correcly the shifting between the two smallest until I saw your video. Routing the cable the way you did solved the problem for le too. Thank you!

I don't think so, I think the pull ratio is different

I've never dropped a chain. I'm not sure if that's down to the spring tension, chainring or combination of both

From memory, I think a 9 speed mtb rear derailleur will work with 10 speed road shifters. Not 100% sure mind you.

sorry, no idea. not used sensah kit before.

sensah has an 8 speed shifter

I think no dude.. You can only mix road and MTB groupsets 9speed and below. 10 speed up have different pull ration for RD.

It will not work

i have deore m4120 which is 2×10/2×11 speed will it work in sti? ​@@zykoncito

sorry, no idea. not used sensah kit before.

will work bro

I think road and MTB Shimano shifters are all interchangeable. I can't give you a definitive list though I'm sorry

@@user-bi9tn4mz8i Thank you Bro!

Striving Simon did you work if they road and MTB can mix and match ?

@@stuartcareless9550 haven't finished my project yet. However, It works for my friend's gravel bike. He's using shimano sora sti with an alivio rear mech.

It's more robust (more aluminium parts rather than plastic) and it accommodates a larger cassette. 9 speed road and MTB work fine together.

@@user-bi9tn4mz8i in case i got a Deore 10 speed RD.. so do you think it works fine with Tiagra 10 speed brifter then? curious about it..but never tried any steps.

@@EasyTigerSaurus No. I think road and MTB 10 speed cannot be mixed.

@@user-bi9tn4mz8i use 9 speed MTB rear derailleur instead

Is it more smoother than the m3100 alivio?

I'm not sure about 11 speed but am tempted to say it wouldn't work as the pull ratios are different. Anything with 11 ranging to 50 is going to be a stretch; you'd be better off dropping the front chainring size and getting an 11-40 cassette or something. You may have to look into the roadlink from wolftooth (or similar), Good luck with your build.

@@user-bi9tn4mz8i thx

Hi Phil! Did it work? I am doing something similar

@@ruzainihashwam7985 i bought sensah team pro 11s instead of 105 and cassette on 11-28 11s (11-46/11-51 works too), its work fine with rd 5100

@@philschneider4840 thanx!

Did you run the cable the way stated in the manual or the way I've shown in the video?

I ride a Mountain Bike

@@Yuhouo in which case, you should run the cable as specified in the manual and ignore the routing shown in my video... Assuming you are using MTB shifters. What shifter are you using?

@@user-bi9tn4mz8i I use Shimano Alivio 9 speed combo shifters

@@Yuhouo kzfaq.info/get/bejne/l9SKfMqf3dankqs.html probably worth checking out

I think you can. But you need to replace your shifter with tiagra shifter (flatbar shifter)

36t is the maximum size listed on the specification so I wouldn't try going any bigger

I don't see why not (I've never tried personally so can't guarantee it). Try it and post your findings

@@user-bi9tn4mz8i sure. I wanna make a gravel/bikepack for mountains

@@andredo4880 I've since moved this setup over to a gravel build. Kept with a 42t front chainring using 650b wheels. I think 650b give a lower gearing over 700c. I also have a 36t front chainring in the drawer as an option (not needed to use yet though). Depends on the terrain I guess. Prefer 1x on gravel personally.

@@user-bi9tn4mz8i bikepacking means +15/20 kg. I usually make about 1800 metres up during a 100 kms ride. I got trek domane but 1:1 ratio is too much for such hills. I also like 1x but i think for bikepacking 2x9 would be better

No, but you can buy them for a few £. Jagwire make them

@@user-bi9tn4mz8i thanks. So we can add a barrel adjuster at the rear derailleur m592 correct ? And how is the gear shifting with m592 is it harder to shift since this meant for mtb or smooth?

@@vishalkarna3763 you can add an in-line jagwire barrel adjuster. I don't know how it compares to MTB shifters, sorry

@@user-bi9tn4mz8i thank you for your response. One additional query, after you installed M592 derailluer, when you have to remove the rear tire, do you have to remove M592 derailluer as well ?

Just take the gear cable out and use it as a brake lever

@@user-bi9tn4mz8i does it has lock screw so i cant shift the lever for brake only?

@@bryanp5979 I don't think so. The lever still moves if you try to shift up or down but there's obviously nothing to shift

@@user-bi9tn4mz8i appreciate your reply

It may be worth checking you've run the chain the correct side of the tab in the cage - I think it should run behind the tab rather than in front

@@user-bi9tn4mz8i Thanks for the reply.👍 Do you mean running above it rather than beneath it as I have it currently?

@@mrmurder75 yes, run above 👍

@@user-bi9tn4mz8i Thank you, I'll try that. Appreciate the help 👍
