Oh no… NW chainring busted my carbon crankset.
Can’t see any way a narrow/wide is different from any other chainring, as far as fitting goes… But fitting/refitting rings of any sort probably does stress the cranks more than everyday use.
Raceface parts on Raceface parts, I’d be speaking (politely) to them about it, as if there’s an incompatibility they’ve kept very quiet about it. But I think you have a crank fail rather than a compatability issue or chainring fail.Posted 3 years agonemesisSubscriber
Is the chainset 1x specific? If not, it may well be that tightening a chainring bolt directly onto the spider (rather than onto another chainring as normal) has caused the crack and that you needed to use a washer to spread the load.
FWIW, no washers on my 1x set up on XTR cranks.
And possibly the reason people are having issues with 30T is because the threads are fixed to the chainring meaning you can, in some circumstances, tighten the bolt more. Normal chainring bolts can spin when done tight (though certainly not always).
And furthermore(!), along the washer point I made above, the contact area with a 30T is quite small compared to a normal chainring – again possibly causing a crack, particularly on a chainset that’s prone to cracking.

So I have a set of Raceface Sixc cranks, popped a 30t Raceface narrow wide chain ring on there and went for a ride… noticed it started to creak, checked it and the 2 of the crankset bolt holes have cracked.
Have I missed something… are they not compatiable??
I am gutted as I simply can’t afford to replace them and I do want to go with the single up front so if i get it replaced will it happen again?
The other problem I have is that I have a Raceface Evolve crankset ready to go on my sons new build, is it likely to happen again if I set his up with a single?
Any info or similar experiences would help me figure out what to do next.
Thanks from one very depressed mtber.Posted 3 years agomallorcadaveMemberrichiethesilverfishMember
