Yes, have a quick search. there's a few companies around now doing them. from memory, works components and wolf are two.

superstar have got one in the works by the looks of some of their fb photos

I've got a wolftooth 30t, havent dropped a chain yet.

Wolftooth, Works Components, Absolute Black, goldtec have apparently got one coming, as have E13, Race Face....

Very impressed by mine. Tried some rough dark peak descents and still not dropped a chain.

I can vouch for the Works one, got a 32T on my hardtail and haven't dropped the chain once since it's been on.

Wolftooth here too, faultless. Nice guys to deal with too.

Had one from the first per-order and has worked great, v pleased.

Tbh why bother importing from the usa and paying s premium or paying £10 more from raceface?
