Compare to other ChainGuides
MRP System 1 (MSRP $148) - 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).
