Did you go with the aldhu for your live avow? I was considering switching to a 155 mm crankset for my liv avow.

If you've got a BB86, yeah don't put anything with 30 on the bike as it is a durability concern. The bearing is too small to survive torture. If you're smaller and willing to replace the bearings seasonally, you can get away with it. There are two basic sizes of cranks 30 (bb30, pf30, etc) and 24 (Shimano, BB86, Sram GXP), plus a few odd balls (Sram Dub). Sram Dub (29), Sram GXP (24/22), or Shimano (24) standards work fine in your bike. Sram GXP might also be a good way to go here and more economical than the Rotor.

That Rotor piece is a good flexible unit, but I'm not sure about rotors direct mount (spiderless) rings as far as selection goes. Sram Direct Mount is the way to go for selection and price; Rotor for minute adjustability. I'd pass on the minute adjustability. With the spiders, they've got two - 4-bolt pattern, it is likely the same as Shimano (I believe it is based on this - https://www.bike-discount.de/...s-4-arm-110mm-691172 ), it may not be. The 110 x 5 spider is a common size. If the 4-bolt pattern is the same as Shimano, that would be a good option and you could use your current chainrings, saving $100.

You might consider this https://power2max.cc/...ion-24mm-with-cranks if you have your wallet open. You're looking at $~350-450 for the Crank as is.
