The bike gained some more grams, I had to replace broken CF tension pulley from eBay with stock one. I've already glued CF pulleys once, maybe I'll try that again, but messing around with dirty drivetrain was too much for today. Another change was a new 50t Fibre-Lyte chainring, my previous one lost a tooth to a curb, which rendered 50/12 noisy and 50/11 straight unusable. No fun jamming/dropping a chain going down at max speed. The issue was fixed, now on 50/11 the chain only rubs FD slightly every several rotations, should be good enough. I did not get the opportunity to weight crankset parts before, so here you are. Those male chainring bolts are steel, so I ordered a set of aluminium KCNCs. The Zipp manual mentions that "you'll need 5mm and 6mm hex keys to work the bolts", but female ones clearly require a chainring bolt tool, I think those aren't stock. I wonder if the person I bought these from still visits WW.
I think the guide jockey wheel unglued from bearing and moved to the left, I shifted down at crossroad and stopped, when I resumed movement the chain jammed between the jockey wheel and RD cage, then a loud pop and rear wheel stopped moving. Last ride the same happened, that's why I put the stock tension jockey wheel back. That was super stupid of me, I didn't think about what actually went wrong, I should have replaced both jockey wheels to stock. At least this happened 5 minutes into the ride, so I walked back home, grabbed my MTB and went for a ride. Whoever uses the same J&L wheels from a couple years ago, be careful. Carbonice pulleys look nice, any other suggestions?
Apparently, RD-5800 and RD-9000 cages have tension spring hole on opposite sides of axle, so I decided to play it safe and just put RD-9000 pulleys and inner cage plate on RD-5800. As I was afraid, the right dropout received some cosmetic damage. About 10 of chain links are bent to various degree, which makes it too short for any of my bikes and I don't have enough of master links yet to piece something more usable together from links left after the initial chain cut. I ordered a couple of new PYCs, a RD-R9100 SS and two sets of Carbonice pulleys while at it.
Turns out Carbonice pulleys aren't compatible with RD-R9100/RD-M9000 because of pulley bolt shape/thickness, despite claimed "can be used for all 9, 10 and 11 times cogsets". No lightweight pulleys for me until alu bolts from eBay arrive in several weeks. At least I dropped several grams from chainring bolts and RD housing (RD-R9100 needs less). I reused XEX-SL instead of heavier OT-RS900, the bend wasn't anything special given 12cm between chainstay housing exit port and hanger bolt.
