1×9 chain keeps falling of ideas please
running a 1×9 on my commuter with old ramped middle chain ring and a Race face bashguard, chain is pretty tight on an 08 Xt r mech dont think its a short cage , and the chain keeps dropping onto the bb side when in high (easy) gear. Chain to tight/ loose, anyone recomend a chain guide . CheersPosted 8 years agoTheGingerOneMember

As Tandem Jeremy says, but maybe have a look at the chainline too. Make sure that sprocket 5 is as close to directly inline with the front ring as possible. If necessary get a new bottom bracket (assuming you’re using a square taper that you can get different axle lengths for).Posted 8 years ago2bitMember
I had similar problems with my 1×9 set on my scandal 29er.Posted 8 years ago
Totally sorted & v v happy with a Rohloff chain guide – http://www.rohloff.de/en/products/speedhub/chain_guide_cc/pauleMember
If you can get hold of some sort of clamp to go round the seattube, then I can send you a basic chain guide like the one I made for my 1×9. Very simple, just a 2″ long upside down L-section of nylon with a counterbored hole for a bolt to attach it to the clamp. Side of the L goes next to the rind, top of it above the ring.
Works well so far, and that’s on rocks rather than just commuting.
Send me an email if you want a pic of my one…Posted 8 years agooxym0r0nSubscriber
Go for the Chain Guide if you want to be sure. If its only for commuting the jump stop ‘might’ work!
The jump stop ‘does’ work – I’ve been riding with TheGingerOne on the Quantocks and Cwm Carn with his fully rigid death-machine and the chain didn’t jump off once!Posted 8 years ago
