So new cassette and chain arrived and about to replace when I noticed the front ring looking a bit worn...so I need a new one.

SRAM chainstay but how I tell if I need an offset ring or not? Also, the single ring looks expensive, other than SRAM what else is worth looking at that will fit the SRAM crankset?

Ta...are they decent? Teeth don't look very tall...does that not let the chain jump a bit?

if its a 1x chainset then you can get steel narrow/wide SRAM rings for direct mount or 94BCD spiders for around £13 - do a perfectly good job and a bit more durable than aluminium.

re: offset, does your frame have a boost sized backend or not? If its boost and the chainset came fitted with the bike then chances are the chainset will say so.

weird - OK, well search for SRAM X-sync steel chainring and that should do it.

FWIW, I've had Superstar rings as well and they are fine but prefer steel for longevity and at that price you can get a couple of sizes if you want to muck about with ratios. The tooth height is less important than the width - it's the fact that the teeth fill up more of the space inside the links that keeps them the chain from coming off.

Right more investigation...it isn't a direct mount! Has a spider, so can I get a direct mount and replace ring and spider? Sram X1-1400 gxp from 2015.

If not, appears to be a 94bcd.

Sorry for the thick questions, but thanks for pointers.

The spider should be removable if you want direct mount, if you take the crank off there should be 3 bolts holding the spider on. Just undo then and pull it off, DM rings will slide on in place.

Nice, thanks for the info...at present, my wallet is talking to me so I'll just replace the ring and get a direct mount next time round as the replacement ring is cheaper than a DM ring.

Actually, just checking this now - I don't have boost, so I'm assuming if I did go Direct Mount it would be 6mm offset, yes?

I should probably not post up questions whilst on holiday in a hotel unable to check anything myself on my actual bike!

As luck would have it, you need this (sorry for the shameless plug):

https://singletrackmag.com/forum/topic/for-sale-sram-eagle-32-direct-mount-x-sync-chainring-bnib-20-posted/

An an absolute bargain and brand new. I removed it from a chainset that came with a groupset because I needed the Boost version. The correct spacing for your set up (6mm non Boost). Works with 10, 11 and 12 speed. Comes with the bolts you need to go direct mount. Would convert your chainset to direct mount at a snip of a price.

According to the SRAM website it is as simple as removing the spider and replacing it. This was in the links from your chainset on their website:

I am in Canada on business until early Saturday morning, but drop me an email and I can get it posted as soon as I get back. 7solarider7’at’gmail’dot’com.

Just found this, so assuming yours looks like this on the back, you’ll be all good.
