Does anyone, or has anyone, used one? If so any good?

From what i have read on the world wide web, some people have succesfully run XX1 with standard "teethed" chainrings. With a clutched RD of course. But you might want to add some sort of chainkeeper.

I have also gotten confirmation from a Sram Rep. that the XX1 and normal 10 speed chains have the same internal measurements. So that shouldn't be a problem.

I would be interested in getting a XX1 chainring from them as well but I don't think Fibrelyte make any XX1 chainrings because of the threaded inserts. I asked them last year or so if they could make XX chainrings but they said no due to the problem caused by the inserts.

I bet they could make chainrings with splines, to fit XX1, S-Works/Lightning and Hollowgram. Carbon Ti have just released titanium Narrow-Wide chainrings like that.

It would be a very cool and sexy addition to a WW MTB build.

I have contacted them about non-XX1 chainrings.

It is no problem to manufacture one, but the durability will suffer in MTB conditions ie. mud/sand.

I am tempted anyway, we'll see.

True it will wear a lot faster in mud/sand conditions. However, if you keep it clean it will last a while. I've been using them on my MTB for a few years now and i replace them after 2-3 seasons. I always keep them clean (quick rinse after a ride). Their pulleys seem to last a lot longer and i only clean them once or twice during the season. Had to replace them only once.

These are mine after 3 seasons:

2-3 seasons is not bad at all - I might give them a try then.

How is the shifting? Have you ever chipped/broken a tooth in these chainrings?

BTW. Post your MTB in the gallery as well.

The shifting is excellent! I never had any issue with them. I have slightly chipped a tooth a while ago but it didn't affect the shifting performance at all.

When i replaced my chainrings at the beginning of the season i noticed that my old chainrings had two missing pins on the back (they are glued to the chainring). Probably just normal wear :noidea:

The rings itself will hold up fine, the only question is the durability of splines, they have to bear with a lot more force and the carbon fiber is not good under compression between layers.
