Hi,
I'm upgrading my Vitus Sentier 2015 from 2x10 to 1x10 using an SLX M7000 11speed rear mech and a Sunrace 10speed 11-46 cassette. I was under the impression that this setup would work together well.
I've just fitted the rear mech ensuring that the 'stop' on it is resting on the derailleur hanger and have the B-screw adjusted all the way in. However when pushing the rear derailleur over by hand the top of the jockey wheel is still virtually touching or only has 1mm clearance to the 46-tooth cog.
Is this because the derailleur hanger was not designed for such a wide-range cassette? Can I just fit a longer derailleur hanger or is there any other adjustments I can make that would help?
Thanks.

Most probably... at least the mech and cassette work on 3 of our bikes (if you include the XT which is identical in terms of range)
Weirdly the mech hanger on two identical rear ends wouldn't play well with a 10sp and Saint rear mech...
Cheapest option is probably a sunrace "goatlink" copy
Yeh I've seen those, I've also seen longer B-screws, would that work as I only need an extra 6/7mm of clearance?
Best would be to find someone with the same chainstays... I guess you could shim it in the stand to check how much longer the screw would need to be by sticking allen keys in between the B-Tens and hangar?
I had this problem recently putting a eagle cassette on because I didn't have the right length hanger fitted. I just found one with the correct fitments on eBay which looked just long enough to work and it did! Only cost a fiver.
Hi guys,
Fitted a longer B-screw and I think it's done the trick. However, I've gone to fit my brand new KMC X10 chain and it's about 3 links too short!!.
Is this because most 10 speed chains just aren't made for wide-range cassettes??
Any advice appreciated.
Thanks.
How many links are on it? I had to use all 116 links on my 11-46 M7000 set up.
I had a similar problem with the b-screw on my Vitus Nucleus but it wasn't quite so bad. I think I have only a 3mm or so gap. I didn't bother getting a longer screw as it performs okay.
Thanks for the info!
My new one appears to be only 114 links which would explain the shortfall. I actually have some old links from new chains I've shortened in the past but not 100% sure they are all 10 speed, is there an easy way to tell or do I need a micronometer to make sure?.
Wish I'd checked now how many links the new chain would have before purchasing as I knew there were different lengths just always had to shorten them in the past, so didn't think it would be a problem.
Finally got the chain the right length by using 2 spare links I found and joined them with two pairs of quicklinks. Just been a ride, shifting seems ok but it sometimes jumps up 2 cogs towards the last 2 or 3 cogs at the top of the block.
Also, sometimes when in the 46 tooth cog my shifter still has one more click in it which doesn't do anything. Tried tweaking things with the barrel adjuster which has helped but may need some more tweaking. Think I have the stops setup right now too, derailleur, jockey wheels and chain or look to be inline.
Any further tips appreciated.
Nice one.
I'm no indexing guru and I've never mixed 10 speeds and 11 speeds so I cannot speak for those particular issues but mine did need a fair bit of tweaking of the barrel adjuster during the first few rides. It's probably not because of a bad chainline but that's one other thing to check. I ended up using chainring spacers to get mine running a bit quieter in the low gears.
Shimano 11 speed has a different pull ratio than 10 speed. Shimano kept it the same from 8-10 but had to change for 11. That's why the 11 speed mech won't shift well on 10 speed shifters
7 (possibly 5) to 9 actually, 10 was the first change.
You have the chain removed when pushing the derailleur over?
Try pulling the cage forward towards the crank at the same time as you push the derailleur in towards the low years (as if there was a chain on it) - the top jockey will move away from the cassette

I had heard about the different pull-ratios but other people hve used the same mix of components and had no issues so I thought it would be ok, I need to do some more rides/tweaking before making any decisions on replacing derailleur etc.
