Rated 5 out of 5 by Sasquatch A bit finicky to set up, but well worth it
For lightweight chain security, this is brilliant. It does take a little time to set up properly to minimise/eliminate chain rubbing, but once you have taken that time, it is excellent. Does it's job well. I have managed to drop the chain a few times, and this has saved me a few times. A quick backpedal puts the chain back on and allows the ride to continue without stopping.

To george - THIS IS NOT A FRONT DERAILLEUR, THIS IS FOR SINGLE CHAINRING SET UPS TO KEEP THE CHAIN ON THE CHAINRING!

Rated 5 out of 5 by Anonymous Surprisingly good
Seat tube mount is much easier to set up than the BB mount version, worth the extra $. Sure it is expensive but it is well made and looks awesome. After a bunch of really hard rides this is way better than I though it would be.

£80 for a front derailleur that doesn't work. More than double the price of the BB mount version. A joke.

Rated 3 out of 5 by Anonymous Insufficient chainline
Previously had a Pauls chainkeeper fitted to a Rockhopper 1x9 setup which was simply elegant. Having upgraded to a Carbon stumpjumper frame the Pauls would no longer fit as required a round downtube closer to the BB.
The E thirteen solved that issued by seating higher up the downtube (without having go to the BB mount versions) Unfortunately the lack of chainline adjustment in comparison to the Pauls makes it impossible to set up without chain drag in bottom 2 and top 2 gears.
Set up is an SLX crank, with a Middleburn 32 tooth non shifting ring, and sram 9 speed.
3 stars because the E-thirteen appears well made, and is light and well thought out (but not as bling as the Pauls).
Have since fitted the Pauls BB mounted guide and works a treat.
