Chain guides.
Things have lightened up since the days of the Mr Dirt devices.
Top is the Black spire Stinger came stock, not running Dualie so back in the box.
Left the old E13 LG1 bit chunky, already attempted to fit and it requires some cutting and filing to clear the chainstay. The blue skid plate was from a smashed but then cut down SuperCharger bashring. 1/2" thick plastic over the thinner Alu rings. No bash ring used with the LG1 so they worked well in mud. Months after I bought mine they started supplying the skid plates in the box....
On the right a Gamut P30 (or 40) named on max size range of chainring so the 30 was good up to 40t and the 40 good up to 50t or something like that.
Very simple and strong and a few years progress much lighter than the E13.
