I run one of these for DH because it is too much work getting thread-locked bolts off to change it. Having said that, it is very reliable and simple. I don't believe it is possible for the chain to come off, and it will survive anything. If weight is not a concern, it is very good.
This chain guide is one of the best and most reliable one out there, Its almost a mount and forget guide. Huge bearings that last long. Metal plates that takes tons of beatings and doesnt crack to peaces like the other plastic chainguides. And it really does its job. It keeps the chain in plase. It makes just a little bit more noise due to the metal plates instead of plastic ones, but id chose quality over plastic fantastic any day.

This is the chain guide that started it all. Literally. Sandwich style, the System 1 gets it done with a guide ring inboard and outboard of your chainring. It’s super simple and extremely reliable. Frequently imitated, never duplicated, the original System 1 is still one of Steve Peat’s favorites. Designed primarily for frames with elevated chainstays (may require longer BB spindle).
