Chain drop off crank on 1x11

[Runbikeswim]

I have a xt 1x11 set up. My chain drops off the crank when i do a bouncy/rocky decent and i am in any of the bottom 3 ( furtherest right) gears in the back.

 

Clutch is engaged.

 

It is to be noted that there is a bit of play on the chain when in these gears. Chain and whole set up is new on new bike.

 

Do i need to remove a link?

remove two links and have a look 

 

also are you on the first or 2nd gen shimano chainring ? ( post a photo if possible)

What this guy ^ said. 

 

I'm running a 2+ year old Race Face NW ring. 'Thing is beyond it's best before date, but still no chain drops.

1 x chain drop.....

As a dinosaur still with 3 x this brings tears of joy to my eyes

 

Sorry OP, just some sick triple ring humor from my side

I’ll certainly have a long and critical look at chainring and the chain length after that.

chain length looks good ( i actually think mine might be longer ) 

the chain ring is also the better one 

 

is the chain the right way round ?

 

I'm not sure what the problem could be cause the way it looks everything should work 

 

 

since the bike is new take it back to the shop if you can't sort it out yourself

Jip chain right way around... but there is no issues apart from the drop and only on bouncy sections.

 

Maybe i must add, was 2x 11. I just removed the derailer, shifter and small cog.

Stop pedaling to and fro when you go downhill. Sometimes chaindrop is a driver error.

Nope, not in this case. Never had before with similar set up

IMHO without a NW blade at least a chainguide is needed no matter how good your setup may be ....

Chain drop on a 1x11 setup normally happens when your chain is to long or your chainring isn't made to go 1x11 if that is the case you might want to get a narrow wide chainring

wait wait wait 

 

are you running 1x11 with the old 34 outer ( 2x11) chainring ?

 

if indeed the case then you need to get NW chainring

I looked at the picture now.

I think you nailed it
