How to prevent chain dropping on 3x10 setup

King_Pin_Rich

Hi Guys,

I'm finding I keep dropping my chain over the rough stuff on my Canyon Nerve AM. It's a Triple ring (Deore XT) setup up front.
It always drops onto the inside, usually ending up resting on the BB shell. The front shifter sometimes saves it and I can encourage it back on with a half-shift. It doesn't drop during shifting and everything is fine otherwise.

Any suggestions? The MRP XCG looks like a potential candidate but I've read that canyon frames have non ISCG mounts unless you use an adaptor (which incidentally I can't find anywhere on the website).

Ta.

sounds like the bottom stop screw is just off.

but why are you in the grany ring? shift to the middle and pick a bigger cog on the rear.

Yeah on mad descents shift to the bigger rings to take up the slack, make sure your chain isn't too long and/or buy a Bionicon v2

Sorry should have said, I do exactly that (middle up front from and larger at rear) to try and take up some slack, still gets thrown off though.

then there is not much you can do other than choose better lines.

How often do you use the outer ring? If you don't use it much consider replacing it with a bash guard and a Chain guide. Some thing like these:

I wondered how long it would take for someone to suggest this. Admittedly I don't use the outer an awful lot so its an idea. I've read stingers et al don't fit Canyon Nerve frames as without an adaptor the tabs aren't ISCG. Canyon make there own chain guide but theres not much information on it.

These look interesting, looks like they would help stop annoying chain slap at least. Love the homemade version!

Yeah, i just used an old rear reflector mount tied to the gear cable with a few bits of soft heatshrink plastic in it. It's completely stopped my chain dropping and there's a lot less chainslap now!

you can buy a version of the stinger which doesn't need the tabs, its just fits in between the bottom bracket and the frame, thats what ive got, never had a problem, since i got it.

The OP wants to keep three chainrings from what i gather. Unless there's a good reason to drop the outer ring why bother?

King_Pin_Rich

Are there any Canyon Nerve owners out there with chain device/tensioners fitted?

Tempted to try the bionicon, quite pricy though.

Haven't got one but am tempted, as I have this issue too (also with XT triple).

Have still got a Dave's Chain Device from way back and thought about trying that, but (a) it won't fit around the chainstay and (b) <ahem> it's the wrong colour :oops:

I do remember though that whilst the DCD worked, I couldn't live with the noise and soon took it off. Any bionicon owners care to comment on the noise? annoying or not?
