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.
Getting old sucks, might as well have a nice bike
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
