One of the nicest sprockets I've seen ... features thick/thin teeth to help keep your poorly adjusted or worn chain in place. £29 seems like a fair price too when you consider the work in them.

Looks good. Going to hold out for the steel version I think, for longevity. Also a 19t option would be nice...

Thick-thin on a SS cog, 10 or 11spd chains? no 17 or 19? I'm lost .. : )

Just use a non-geared SS chain and it won't jump off even when loose, I have an oval ring that creates a lot of slack at some points but has to get really baggy to bounce off.

Would go quite well with one of these

Seem pretty good for the price (no actual experience of them though).

Im left wondering why we need a thick/thin sprocket at all???
Can someone explain to me why a properly adjusted SS would need it? Do people have any real sproket trouble that they need this
I too run an oval ring, and even when at its slackest point is still very secure

No 17 or 19T, not able to do thick/thin. Even numbers only

It does manage to get closer to the all-time high point of SS cog porn than most though.

Exactly, at some point before making one I'd have said 'this NW thing is a crap idea for a SS cog, isn't it?' : )

[Bearbonesnorm]

I view the 'benefits' of the tooth profile as a bonus ... I reckon it looks a really nice sprocket at affordable money, regardless of T/T teeth.

Is that your Boone James?

[jameso]

No chance, not at £150+ or whatever they went for..

A super-hardened cr-mo, Boone-styled oval 34 ring, I'd pay a bit for one of those if anyone made one. Al stuff on a SS isn't great really, don't see any point in using an Al sprocket. Agreed that it's a nice option for some at a fair RRP, ie better one NW option out there than none.

This is the nicest ss cog

I've not used one of them but I've had a couple of chain rings from marcin at absolute black. One 34t thick thin for xt cranks and one regular 33t on a 94bcd for fsa carbon cranks.

Both are beautifully made and marcin was super helpful and I'd recommend him.

[FLV]

Looks ok. Wish he'd goes through with the cutouts, and ditched the narrow wide.
I guess if the demands out there he'll Lilly add more sizes.

I still like the Chris king as one of the nicest sprockets. Simple, good looking and made of steel

I've not seen a chainring as nice to match. Yet.

never had a ss chain issue until i deliberately let it go very slack, using several brands down to £5 shimano rear rings, only need thick thin on the front if running 1/10-11 set ups without a chain guide, more marketing hype
