It’s lighter than a single ring and guide.
It costs less than a standard single ring and guide.
Seems to keep the chain on as well as a guide so far.
Less places to clog with mud than a guide.
Easier to clean/remove/fit the chain than when you have a guide.
Fewer moving parts, less bits to break than a guide.
Chain and frame stay cleaner because there’s no guide to gather gunk.
Running a Works 32t in a 1×9 setup. Not lost the chain from any bouncing about, but a mud-covered chain comes off when back-pedalling even half a turn. Shifted a bb spacer to the non-drive side so we’ll see what happens next time.
How do they work 9 speed?
Considering options for the old HT, currently set up 1×9 with an old MRP chain guide that rubs and is impossible to set up (crap chainline means cant get top lowest gear easily no matter what I do at rear) plus looks out of place and ugly
Option 1 is keep 1×9 but with a thick thin ring
Option 2 is to single speed (which I fancy trying but could still do after getting the thick-thin ring)
