1x10 problems

[NicoBoshoff]

cage length of DR....just another thought

 

Will have to check, but I'm 90% it's mid cage.

[Captain Fastbastard Mayhem]

Fully extended, as in beyond the point where you can use the lock pin?

 

Yes. The point at where the lock pin goes in is NOT fully extended. Extend it further...

I run a 1x10 with Wolftooth chainring on 29er HT. Absolutely no dropped chain yet and I have ridden plenty gnarly places. It has even held up with absolutely no issues in the XCO races I compete in.

 

Chain length needs to be done as follows: wrap the chain around the largest cog at the back and the chainring in the front. DO NOT route through the rear derailler. Overlap ends of the chain by a total of 4 links. (2 links on each end of the chain). length shouyld be correct.

 

I have added a picture to show you. I just fitted a 42T to my 11/36 cassette on friday.

 

 

On your photo the chain is routed through RD though?

 

I did the loop and check 4 links as recommended on SRAM site, but my chain was at 4 links with plenty of room for RD to go still.

 

I'm just going to do what Armpies suggested. If that doesn't work I may just go with Deore Shadow+ at the back and get new chain and cassette in the process.

[LazyTrailRider]

I'm fairly certain it's chainlength related.

 

Yeah, I think so too.

 

I have not dropped once since running my XX1 chainring and X9 type 2 shortcage with 11-36t combo, and as you know I ride gnarly stuff too.

 

Roneblack46, keep us informed about how that short cage handles the large spread that the 42t has created, it will interesting to know...

Erm, when doing chain length calcs on a bike with a single ring up front it is IMPERATIVE that you run the chain through the RD.

And a new shifter?

Yip, would need a new shifter...I would go Z if that is your plan nico

[NicoBoshoff]

Just came back from LBS and they reckon it's most likely chain length. They have never had a return on an X9 clutch going, but quite a few Shimano one's.

 

The mech also recommended possibly increasing cage tension slightly.

[NicoBoshoff]

Just for future reference, if my RD is wankered, I will go X9 again. What length cage should I go for then?

 

Seems mine is long cage (SRAM site states mid cage is only 11-32 compatible and my cassette is 11-36, which is listed under long cage).

It SAYS that, but if you dig a bit more they actually say it has a 37t Capacity... which is the overall difference between the tooth count on the back and front added together. So - if you're running an 11-36 your capacity only really needs to be 25t to allow it to work. Which means you can go medium or short, but the Short cage probably won't (and Flowta can confirm this) be able to take up the slack between the cassette's top and bottom ratio.

 

The Medium cage can theroetically take up to a 48t cog at the back if your smallest is an 11. That's taking into account the capacity rating of 37t.

Your LBS may not be entirely correct. I started having the same issue after many months problem free. Changed chan and front ring as thought they may be worn. Same issue. sprayed some oil in the clutch (after doing a google check) problem solved.

 

Bit more indepth explanation, the roller bearing in the clutch starts to dry out over time especially once you have been riding in alot of mud as i have been with the KZN weather been so wet while i was on holiday. if you take the little black cap off the "clutch" you'll see a rather large torque key ( 8mm allen key works too as it doesnt have to be very tight) take that of and you can get some lube in there and clean it up a bit, close it up and it should be back to 100%. Basically what happens when it drys out is when the cage moves forward after hitting a bump in the road, it jams for a split second giving the chain sufficient time to fall off.

 

Havent had an issue since i did this.

AFAIK the ZEE is designed for a single chain setup and comes in 2 variety DH (11-28) and AM (11-36).

 

Other derailleurs SRAM and Shimano need to take into account the front derailleurs too, thus meaning they need a larger capacity.

 

This may account for the ZEE not taking up enough on the 11-41.

3 things to reply to:

 

1) determining the chain length by not going through the rear derailler - I quoted the exact wording off the Wolftooth Components website under FAQ. Now they do not specify for HT or DS. I would think to take all air out of your rear shock and then measure the chain length as required.

 

2) the picture shows the angle of the RD when in the biggest cog with the chain through the RD. you should aim for that angle.

 

3) I had a long cage X9 Type 2 before with no issues. I am now running a X9 Type 2 medium cage with a 11/42 cassette with no issues.

 

Hope this answers some questions.

[NicoBoshoff]

Thanks for all the replies.

 

Tonight I will:

 

- Check chain length as per Armpies' post;

 

- Open the clutch and oil it as per Pat's advice.

 

Will then check on my next ride if it's still dropping. If so, well then I'll be picking your brains again.

I'm running short cage with an 11-36, perfectly. My intention was to get as quiet a setup as possible, so although medium would've worked, the whole hog has turned out well.

Ah yes thanks Dave - forgot about that. ZEE & Saint are a bit different.

 

So yeah - short cage should theoretically work. I'd fo with medium given a future change to 11-42 for me though.
