9 / 10 speed compatability issue

jonnyashworth

I did have a little search in previous posts for an answer to my question but couldn't find one however I'm sure I can't be the first to ask so sorry about that.

I have been looking into (possibly) converting my 2x9 setup on my remedy to a 1x10. I don't just ride downhill stuff but at the same time only use roads to get to the next bit of trail. So it would be nice to hear from anyone who has done this already to hear if its worth doing and what size casette and rings they used.

Also I am running a Shimano XTR Chainset M970 up front and wanted to know if (as a single ring) it would be compatible with a 10 speed chain?

Cheers

Currently running 9 speed rings with a 10 speed chain, no issues to report.

XTR chainset will work fine with 9 speed rings, however you would need a 10 speed cassette, right hand 10 speed shifter and a 10 speed rear mech, the medium (SG) cage would work best.

Expensive way to loose 8 gears!

As far as cassettes go on a 1 x ? setup - I'd go for an 11-36 with 32 to a 40t up front depending on conditions. Still dont think that would give me the gears I need sometimes.

Have a play with a gearing app on a website.

If you want to run a single ring it does not matter as the chain internal width is the same.

would it become a problem if I wanted to run a double or even a triple from tome to time?

Well yes, as you'll need to put the mech shifter chain and rings on each time - quite a lot of effort.

It is a lot of effort but at times the mood might take me to do it. So 9 speed chainset / chainrings are fine with 10 speed chain?

In theory they are a bit different, but in practise it should work.

Yes.

If you're going to run a single chain-ring, you might want to consider a chain-guide up front. I think you'd have to remove the front derailleur if you do this, and as already stated, it's a right faff removing the FD and putting it back.

So I really can't imagine you be happy uninstalling/reinstalling all this should you decide to switch back to double/triple rings for a 'hilly' weekend. Once you've installed something, and it works fine, just leave it.

It would be helpful if you stated what your double rings are currently (I'm guessing 36/24). And what are your concerns about going to a single chainring (e.g. a 34) - is it the loss of the higher or lower gear ratios ?

If you are running a 36/24 up front, and 'plan' to swap them round with a single ring when it suits you, won't you have to remove the crank arm to unbolt the 24 ? You definately don't want to start taking the cranks/BB apart for no good reason.

I really like 1x10 (36t, 11-36 cassette). I changed with the intention to change back for certain races and things with big hills, but it's been absolutely fine, and I couldn't be bothered with the effort (internal cable routing not helping).

If anything I find a bit undergeared on the road, but not massively so, and I'd not want to sacrifice the 1:1 bottom gear.

You can use the existing front mech as a chain guide.

Remove the shifter and cable and adjust the inner stop so the cage is centred over the chain ring then lock it in place with the outer stop.
