Crux 2021
Moderator: Moderator Team
So, up on the stand it looks like the limiter on the SRAM AXS 2X setup with the regular width spindle is the distance between the inside chainring bolts and the chainstay, rather than the chainring teeth. Measures out at about 1mm with a feeler.
Seems like the options are:
1. Live with it, hope everything is stiff enough around that area to avoid issues.
2. Round down edges of those bolts, giving another 0.5mm or so of clearance.
3. Switch to the wide axle, giving a more comfortable 3.5mm of clearance (but wider Q factor).

You're not fitting the spindle to the shell, you're fitting it to the cups. Are ITA cups themselves the exact same width as BSA cups?
I appreciate all the responses to my question, this forum is such an excellent resource. I have the luck (or problem) of finding enjoying qualities in just about every bike I've ridden, seems it is impossible to combine those qualities in a single bike as those ride characteristics work against each other.
UP vs Crux I can buy, but more 700 clearance and lighter weight on the Crux. But Aethos and Caledonia are 2 totally different bikes. Aethos is light, no special parts or integration and made to be fun and agile on road. The Caledonia is all integration endurance roadbike with pretty high stack and not as racy geo as the Aethos.bikewithnoname wrote: ↑Fri Oct 22, 2021 11:11 amYou have an UP, which is essentially the same as a Crux, you have a Caledonia which is essentially the same as an Aethos.
By all means get yourself a new bike, it's nice to have new things, but it's unlikely either of those bikes will offer anything new that is tangible (other than less weight in the case of the Aethos vs Caledonia)

Thanks for the info! What chainrings are you running?
I've got a 48/35 on there right now.FuelForThought wrote: ↑Fri Oct 22, 2021 7:32 pmThanks for the info! What chainrings are you running?
Could you go with the integrated Red rings so there aren't any chainring bolts?cbro wrote: ↑Fri Oct 22, 2021 6:36 pmSo, up on the stand it looks like the limiter on the SRAM AXS 2X setup with the regular width spindle is the distance between the inside chainring bolts and the chainstay, rather than the chainring teeth.

Good question, I'm not sure. This is with the Force 48/35 spider. All else equal, if those bolts weren't there the next-closest gap would be between the chainring and the chainstay, which is a hair greater than 2 mm.LegPower wrote: ↑Fri Oct 22, 2021 8:54 pmCould you go with the integrated Red rings so there aren't any chainring bolts?cbro wrote: ↑Fri Oct 22, 2021 6:36 pmSo, up on the stand it looks like the limiter on the SRAM AXS 2X setup with the regular width spindle is the distance between the inside chainring bolts and the chainstay, rather than the chainring teeth.

What about throwing a 1 mm spacer on the drive side spindle?cbro wrote: ↑Fri Oct 22, 2021 6:36 pmSo, up on the stand it looks like the limiter on the SRAM AXS 2X setup with the regular width spindle is the distance between the inside chainring bolts and the chainstay, rather than the chainring teeth.

I was thinking about that. I have a bunch of 0.5mm spacers. Is there a consensus on how many can be added before it interferes with full seating of the crank on the splines?Ridinghigh wrote: ↑Fri Oct 22, 2021 10:26 pmWhat about throwing a 1 mm spacer on the drive side spindle?cbro wrote: ↑Fri Oct 22, 2021 6:36 pmSo, up on the stand it looks like the limiter on the SRAM AXS 2X setup with the regular width spindle is the distance between the inside chainring bolts and the chainstay, rather than the chainring teeth.

I need to figure out why my headset is creaking...

Wouldn't you just loosen the bearing preload ring? It definitely has 1 mm of lateral adjustment.cbro wrote: ↑Fri Oct 22, 2021 11:12 pmI was thinking about that. I have a bunch of 0.5mm spacers.
