And what sort of setup do you have?
If it’s a 1x, and you have iscg mounts, then these dinky wee guards you can get now are great- they fit more easily than oldscool ones because you don’t have to take the crank off, they’re light, and they’re really simple (because narrow/wides do such a good job of keeping a chain on, you don’t need a monster, you just need a wee gentle nudge). I have a Shovel one, just because that was the only choice at the time, but there’s others now- Oneup do one, rpoabbyl others.
