Change from Shimano 9spd to 10spd derailleur

stevekoz

Hi All,

I've been researching rear mechs for a while as i'm looking to change out my rear mech due to some damage to mine.

I've been given an xt 10 spd mech.

I have found lots of info on mixing and matching sram / shimano. But im having trouble deciphering shimano to shimano.

I have a 9 speed rear cassette, 9 speed triple crank, 9 speed XT front mech and 9spd triple slx shifters. All Shimano.

If i now add a 10 spd Shimano long cage rear mech to this equation would this have any complications? This is all MTB specific kit. Not mixing road/mtb etc. Just MTB shimano to shimano 9spd to 10spd.

Cheers guys and girls.

As it is it will not work as they use different ratios. See the FAQs.


But they are some people playing with spacers to change the wire clamping point to give the same pull ratio as a 9spd mech.

There seems so much conflicting and grey territory online with this its hard to make clear what can go with what.
Thanks.
I will just sell the xt 10spd and buy a 9spd, seems easier than playing with spacers etc.

As Nick said, people are getting good results with a spacer on the cable clamp.

Read this thread to the end.

That thread is the other way around though. This guy wants to use a 10spd mech with 9spd system, most prob as you can't get 9spd clutched mech

And that guy really really did not have a clue. How he said it worked a treat when he was only getting 8 sprockets????

And personally - I can't see this working perfectly, like the correct setup. But like Northwind says some people are ok with poor shifting - I really am not.

That's what I meant. Whatever people say or bodge, it's not worth the hassle for random sh1t shifting.

Meaning what???? :roll:

Chunkers1980

You said good results, Nick neither said that or implied

*AJ*

Apologies, I actually meant

"as Nick said people are using the spacers on the cable clamp... and from what ive seen the results are pretty good"

I'm that guy :oops:
Get a new rear mech and be done with, I pinched my fingers numerous times fiddling around with spacers all night long to get it right after I realized I 8th and 6th cogs where missing, and was sooooo smooth that got me.

We all live and learn.
Now when someone else asks, and they will, regularly, you too can sound like a smug know it all.

Win/win.
