• I'm trying to get 30/46 but it is a pain in the arse as trying to keep stages pm. First attempt was absolute black rings but pm doesn't work properly with them. Am now fiddling around with a 105 triple (with just an inner and middle) but it needs spacers and faff to get the chain line. I don't think I cba, so may reorder the ab rings I returned last week. PM not exactly critical.

  • Interesting to hear about your power meter not working. That must be because of the oval ring and nothing to do with Absolute Black? I Googled and found this, https://powermetercity.com/2016/07/24/power-meters-oval-chainrings/

    I have tried running a triple as a double with an Ultegra 6703. So many things going on there to sort out. Like for example the axle is longer and has a spacer that goes on the drive side. That spacer is not not really the ideal width. The chain angle was worse than the AB sub compact rings with an MTB cassette on a road free hub body and a short chain stay. Some really noisy cross chaining was going on there without actually cross chaining. If you follow that. So I abandoned that project.

    Where I ended up was the Rotor 3D cranks with the one piece 46/30 chain ring. Love that setup. No power meter though. I don't make enough power to merit measuring it, lol.
