I used to have a chain guide fitted on my bike, but got rid of it when I got a thick/thin chain setup. This is PERFECT for still protecting your chain and ring from rocks and log impacts...IDEAL! Excellent quality and anodising, comes with spare washers if you need to space it out from your bottom bracket too..... PERFECT
I was trying to find a chain guide to fit 48.5mm to 49mm chain lines for decent 11s on 26 inch bikes. This one is brilliant and totally adjustable to any chain line or chain ring size.
A little difficult to fit on an Orange Five and Alpine 160 but once on and setup it works really well. It's a keeper on both my bikes.
