I was searching for a good solution for running 5-Bolt 110BCD road chainrings on a SRAM AXS crank I recently picked up for a good price, and found this spider from Stone Bike which promises exactly that. Unfortunately, it is not fit for purpose.

I was searching for a good solution for running 5-Bolt 110BCD road chainrings on a SRAM AXS crank I recently picked up for a good price, and found this spider from Stone Bike which promises exactly that. Unfortunately, it is not fit for purpose.
I was surprised at the sloppy fit of a Quarq meter on my Red AXS crank, the ‘fit’ is provided by the 8 self centering countersunk bolts. Try moving it after torquing those up. The lobes are I suspect more about orientation, bolt mounting, stopping damage if the bolts work loose.
If the lobes were designed to hold the spider they would be on a taper and pressed together with the bolts.
I asked SRAM support about it, and they said the fit should be “snug”. I agree that a tapered interface would be better, but this is what they went with.
Have a look at the spider I replaced this one with: https://www.mamilian.bike/review/2022/01/croder-5-bolt-110bcd-spirit-spider-for-sram-axs-8-bolt. That’s a much better fit.
The Quarq was far from snug, a good amount of rotational play. Anyway, thanks for the tip on the Croder, like you I’ve found it near impossible to source one that’s not a lucky dip AliExpress purchase……
Can’t see the 5 arm Croder in the UK though.
Email them, maybe they can ship you one. We exchanged several emails on the spider before I bought it, and ended up buying some unlisted chainring bolts from them directly using that mechanism.
Cheers
Hi, I watched your video. I used the same adapter to make a 110bcd 1x chainring work with my SRAM AXS crankarms. 2 things: 1) This DJC Stone spider is meant to be used for 1x only, meaning the inner edge or “rear shelf” as you call it is NOT meant to hold another or smaller chainring (the 1x ring goes outboard). Also, 2) the “wobble” you are mentioning of the spider when it’s just put on the crankarm w/ out the bolts is normal, I did the same with a stock Quarq PM or SRAM X-Sync DM chainring and… Read more »
Thanks for your comment. If you’re comfortable using this spider, I’m OK with that. Everyone is allowed to have their own standard. I wouldn’t use it, and I would recommend a better option. Go have a look at the difference in quality b/w these spiders, it’s a vast delta. 1) Can you provide some documentation around this claim? I just checked the Stone product page, and there is no reference to 1x only that I can find, and one of the product images shows it with a FSA 2x ring set installed (see attached). 2) I asked SRAM about this,… Read more »
