Nice quality chainring. Been using it for a year and it's still going strong.

Rated 5 out of 5 by MountainSnail Top quality rings
I started using Blackspire rings about 2 years ago and am very happy with them.
I have a set of RaceFace cranks and quickly wore out the stock rings that came with them, a friend of mine recommended Blackspire and I have not used anything else since then.

Rated 3 out of 5 by Anonymous nice product, well made and you get a 34, yay, dunno why shimano don't. but there is a problem with my xt770 htech2 cranks and my chain tensioner/guide, a blackspire stinger. the chainline on this ring is closer to the bike than the xt ring and doesn't work on the stinger. because i've got a 68mm bb i was able to swap bb spacer placement to fix the problem but if i had 73mm it would be no good and i don't think an allowable 1mm spacer would correct it and i would have been stuck with an expensive ring that had been fitted and probably couldn't be returned and which i couldn't use. if you have same cranks and run a chainguide check with crc about their returns policy on this first. otherwise on my fist ride with it yesterday it was sweet-as, love that 34 ratio!

Rated 5 out of 5 by Anonymous I bought this chainring to replace my old Blackspire chainring - the identical product, which was 6 years old - purely because I thought it must be time to replace it. Comparing the old with the new, I was astonished to find that the old chainring was barely worn (maybe 1mm from each surface) - even after 6 years of abuse and hard riding. Admittedly most of my riding is in good conditions, but still with the occasional mud-bath. It seems that the replacement was unnecessary. Amazing durability, strength, good looks and reasonable weight. Shifting performance is good, although probably slightly inferior to a Shimano XT or better product. Very highly recommended and well worth the slight premium in price. I am keeping my old Blackspire Super Pro chain ring, to use again when the new one dies - assuming I am still riding in 10 years!

le descriptif indique compatible 9/10 vitesses, mais sur la photo, le plateau porte les inscriptions 8/9 vitesses, je cherche un plateau 10 vitesses en 36 dents (104 entraxe). merci pour votre réponse.
