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.
As ideas go, it's a very good one indeed.
I do wonder why no one thought of it before.
They did, its been around ages. Just SRAM claimed they invented it and had the cash to market it.
I have one in the post. Will be using it 1x9 and am intrigued at how well its going to work.
First ride with NW done today and I am impressed so far. Much tidier than front mech or guide. And lighter too.
I want to know if a narrow wide chainring will still keep the chain on so well when it starts to wear?
Running a Works 32t in a 1x9 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.
Its all foreign to me, how does it actually keep the chain on?
9 spd chain is a looser fit plus no clutch mech which is why I guess it doesn't work as well.
I've been running 36t narrow wide ring and SRAM 10speed clutch mech for a while now. Not a single problem so far and as it stands I wont go back to a chainguide.
How do they work 9 speed?
Considering options for the old HT, currently set up 1x9 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 1x9 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)
