[demo 9]

So as im riding (a very smooth trail) at diablo my chain skips a few times before my cranks lock into place. this is what happened. i have absolutely no idea how this happened as i always thought it was impossible for a chain to escape an E13 guide and i didnt know that the chain could do barrel rolls either.

Seems to me if your chain can physically twist like that under little pressure its gotta be pretty beat. Thats pretty crazy though.

Is your chainring old? Worn down teeth can be the cause.

How did you chain end up on top of the upper slider? Also derailleur shot?

cocaine's a hell of a drug

Uhhh yea, you need to change out chains occasionally...when you can twist them a full turn over their length, that is a good sign that you chain is about two years too old.

Your guide is also not set up correctly. Your lower roller is too far away from the bash, and your upper slider is.....under your chain.....I am hoping that you did not do that yourself.

You also have a f*ed chainline.

 

[ridiculous]

you put your chain on backwards.

Time for a new chain, cassette, and chainring.

you put your chain on backwards.

it WAS under the upper slider, how it escaped is part of the magic. I don't doubt the chain is shot, i cant remember the last time i changed it, just surprised that it could actually escape. The chainring was fine but after i take the cranks off, ill see how fine it is now.

This is the first time the chain has came off since 2006 when i got the SRS. So i still highly recommend E13

Looks to me as if your back plate is quite a bit too far inboard. ther is a boss on the lower roller plastic that shold be near flush with the outter face of the bash. The gap in this picture screams incorrect set-up to me. I could walk through that gap....

This picture is a bit telling as well. Your front ring should line up with the middle cog....not the midline of your tire.

wow. that is impressive! I'd say that anytime the chain gets perpendicular to the teeth on the chainring that's going to cause some havoc! If we can be of any help, let us know. support @ e13components.com, see you at the US Open.
