Hi
I have started having issues with chain dropping off front ring, I replaced front ring with E13 narrow wide 34 tooth, all ok for first 350 miles, but ever since on fast downhills chains drops every time if ground is rough uneven. There goes all my KOM attempts lol. Does anyone else have this issue, i think it may be the E13 chain ring, as derailleur as just been changed again now on Shimano SLX and chain is new also and still it drops the chain. Is there any chain device that can be fitted?? I tried the old fashioned DIY chain device fitted to chain stay and it made no difference at all.
