I'm currently running XT drivechain (2 X 10 speed setup) with TA Specialites 38/26T rings. My chain seems to fall off a helluva lot more than when I had the standard 42/32/24 setup. It's not terrible but I do seem to drop the chain at least once per ride. I've just bought a clutch rear mech (not fitted yet). Are there any chain devices that can assist furter for a 38/26 double setup? I haven't got the legs for a 1 x 10 LOL.
Cheers.
Does it drop when changing front rings, or just under pedalling?
You might find that the clutch mech sorts it.
Changing front rings Dan. Yes I'm hoping the clutch mech works some magic - chain device would be belt and braces.
just a thought but I trust you moved the front mech down a little when you changed the rings? Mrs BS runs this exact same set up and reports no issues.
Sounds like a front mech setup issue.
Cheers guys. Any chain devices for doubles?
Ive had a gamut chain device with the aluminium bash on my five. Not dropped a chain once.
On my new 1x10 im hoping the clutch mech alone will do the job.
I don't have a double chain device, but a mate has a blackspire stinger on his and it works fine.
Agree most likely front mech set up, moving it down will probably help. Also, your biggest ring has gone from 42T to 38T, can you shorten the chain a little?
Edit: Front mech set up - move down as the biggest ring is lower now, but also check your stoppers as you now have less rings so the mech might be moving over too far.
+1 blackspire stinger. As mentioned drop the front mech so the cage tracks the outer ring with a 1mm gap and ensure you've wound in the limiting screws to avoid overshooting the selected chainring.
HTH

Brilliant - I'll check up on all that. Any reccommendations on the ultimate tough durable chainrings for double that still shift well?
