The Good: Never dropped a chain, easy to install
The Bad: The white color will turn brown/grey from the chain quickOverall Review: I've used this guide on my 2009 specialized demo, and never had any issue dropping a chain riding in the northern California area including Northstar. The chain guide has great hardware included and you'll never have an issue with striping anything due to the production value. The gold bits are a nice touch, but when I bought white, should of got black because the white will fade when your greasy chain runs thru the dirt and back thru the guide. I've never had a bammer product from e.13, and this latest guide is wayyyy ahead of the older style clunkier DRS that I ran on my AM bike a few years ago. The new LG1+ is much smoother and quieter.
