RaceFace 4-Bolt Light Bash Guard
There is a size and color for all your rigs. Designed to protect your middle and inner chainring from impacts while keeping your ride looking good.
This is the second Race Face bash guard I've installed and I am very happy with them. The lightweight, high strength aluminum provides great protection (much more than those wimpy plastic ones) but also give a low-profile look. I thought $30 was kind of pricey but after shopping around, I think this was a decent deal. If you want a reliable bash, this is it!
I am very pleased with this purchase. I've been riding with it for about 4 months now and cannot report of any problems. Works well with an e13 chain guide.
