    e13 SRS rubbing chain

    Two weeks ago I had the SRS installed on my 1x8 HT. Last weekend noticed that in gears lower than 4, the chain is at an angle that rubs the inner plastic guide.

    What should I do to correct this?

    File down the plastic guide where the hain rubs and make a chain "channel"?

    Use spacers to move the guide closer to the BB so the chain doesnt rub as much?

    Any other suggestions?

    I had to play with mine for a while to get it right also. Basically your chainline is "out" too far. There's a few ways to try to correct this: make sure the iscg mountain bracket (the silver thing) is mounted with the cup side IN. Also mount it directly against the bottom bracket housing (with no washers) and if you're using a bb spacer, put the spacer between the iscg mounting bracket and the bb. Although your chainline looks pretty far out so I wouldn't use the bb spacer at all. The idea is to get the chainring and chainguide closer in to the bb if possible. Ultimately you may need a shorter bb. For 135mm rear hubs a 113mm (115mm at the biggest) bb will give you an optimal chainline. Sucks to have to pull the bottom end apart but a bad chainline will wear your chain out in a hurry. Mine rubs a little bit in my higher gears also (I'm running a 118 bb) but my chainline isn't bad. I wouldn't advise grinding or dremeling your chainguide though...the problem is your chainline. Correct that and the rubbing will go away. Hope this helps.
