Set up the El Guapo to run 1x10 with the following (All brand new): 32T Hope N/W front chainring XT clutch mech 11-36 XT cassette One Up 42t XT Chain Everything went together fine and it seemed to index just fine, in fact it shifts lovely on the work stand. However when the drive train is under load it's a completely different story. It shifts up the cassette fine but then when you want to come back down next to nothing happens. It'll drop from the 42t into the 36t fine but then it just seems to get stuck. It's seriously starting to piss me off now as I've tried no end of adjustment. I'm beginning to think I should just stick it in somewhere and let them sort it out before I end up taking a hammer to it  |

Im having problems too, its as if the tension is too tight on that ring so wont shift down...my conclusion is ive got a medium lenghth cage on my mech when i should have a short cage for 1x10,.zee mech on its way,hopefully that sorts it

Have you checked your chain length? also have you installed the 16t cog? All I had to do was take the little placcy washer out from behind the b screw and it shifts lovely. Have you got the long cage mech? mine is long cage which is recommended.

Fingers crossed for you matey. It's just really annoying, the only way I could get it to shift down yesterday when I was out was to raise the back wheel off the ground while riding and slam it back down, the force of it would knock the chain down to the correct cog lol

All my shifting probs were down to b screw tension,once I fitted the rad cage it sorted everything out.im running medium mech but it looks sooooooo long compared to short zee mech.

If you've got an expander cog then you need a long cage mech, possibly the rad cage too although I haven't needed one on mine.

Have you got the one-up the correct way round, I think one way is for xt and the other for sram iirc ?

Everything is correctly installed, I've double and triple checked. It's a medium cage mech which I also thought was the recommended length. Chain length is fine and the one up 16t is fitted. The problem is shifting downwards out of the 36t. B screw is wound in as far as it will go.
Really wish I had just saved my money and kept the 2x10 which ran sweet as a nut. The more I look at the set up the more I don't like it, it's a total bodge of components!!

Gaz just checked on the one up site and it says medium or long cage mech. So we were both right. I can't understand why you are getting those symptoms typer - difficult to say without seeing the set up. Have you taken the placcy washer off the b screw? mine wouldn't change correctly until I did this. It allows you to wind in it further, failing that you can get a longer screw from a hardware store.
It works great for me, though I can see your frustration.

I couldn't see any plastic washer but I'll have a look when I get home from work. I just don't understand how it shifts perfectly when on the workstand and then doesn't as soon as it's under load. Never had a problem indexing in the past but maybe it's time to give someone else a go!

What you are saying suggests to me it might be a 'chain growth' issue? ie did you measure and cut your chain with the rear shock deflated of air and the bike 'bottomed out' on the rear?

I did do it like that but the chain was way way to short, so I did the usual big cog to big cog and add two links..... worked fine on my 2x10 set up

I think we might be on to something here mate, the fact that it shifts fine when on a workstand, but is shoite when loaded (ie the chain needs to grow) says to me it might well be chain length. Chuck a couple of links in just to test the theory - but if your chain was too short when you deflated the rear shock - it could be that. All I can think of.

I had to take that out so I could get my B screw in further !! |

I have just installed a oneup components 42t and rad cage to my Nukeproof. I'm finding that the rad cage and top pulley are fouling the RD (shimano xt shadow plus medium cage) when going into the 11t cog. I have tried shortening and extending the chain. Adjusted the b limit screw both ways fully seems to make no difference. I'm at the point where I'm going to take it all off before the big hammer comes out!

B limit screw needs to be as far in as you can get it, with the little placcy washer off the screw. If it's still fouling the rear mech you need a longer B screw - couple of pence from an ironmongers.
I know I smashed my first rear mech because I hadn't set the B screw up properly the first time around.

I feel your pain mate, they really are a faff to get set up. I'll stick some pics up once I get home lads  |

Finally got mine sorted! B limit screw is set just biting into the plastic spacer. Had to put lots of links back into chain (112 links total length plus split link). Took it for a quick ride up the road shifts through all gears ok. Need to get out for a longer ride later in the week to check up hills and over rough stuff.

check that the mech plate isn`t fouling on the 42t ring,it could be overlapping slightly and sitting on the inside of the teeth. I could be wrong but I think one up recommend a longer chain length than the `big to big plus 2` method. you`ll get it sorted stu,someone who builds bikes to a standard that you do won`t be beaten by something as trivial as this. it`ll also make me feel better when you get it set up right cos I told you how much better than 2x10 it is  |

Cheers Paul, I've never had indexing issues in the past that's why this is pissing me off so much. I rode Chopwell yesterday and the range of gearing seems spot on so I'm hoping I do get it sorted. Anyway, I had another fiddle when I got in today and I think you and Zulu are right about chain legth and the mech plate rubbing. I noticed this rubbing on the mech plate:  Like you said I think this is catching on the 42 and 36t cogs when under load and the rear suspension is compressed. So did what others have mentioned and removed the plastic insert that sits under the b screw and wound it in as far as it would go.  This has improved things a bit and now the mech cage doesn't sit as close to the 42 and 36t cogs. I'm now thinking if I add another link or two to the chain then that should give the clearance it needs for shifting down the cassette. I didn't have any shimano chain pins so I couldn't add any links to test this out, but I'm hoping this will sort it. I'm sick of messing about with it though so it's booked in to get looked at tomorrow |
