>200w / 80rpm clicking noise which gets worse at higher torque times. If I double pedal I can minimize it. Light smooth pedaling .. nothing. heavier pedaling .. clicking.
With Campy UT it's a fixed width so one can calculate stuff out, although a major PITA.
Did you fix this? It could very well the chainring bolts. It has happened twice to me with Campy. Until I figured it out I went nuts replacing saddles, pedals, seatposts, QR etc.
Take the crank apart completely, clean the bolts and chainrings and inner threads, add a bit of grease the the bolts and torque to 7 (8 is recommended for dry but I think a bit of grease is a good idea). Doesn't hurt to also clean and wipe the cups in and out, washer, Cclip and its groove either.
it is a non-drive side bearing failure.
some detail: taking the crank off the bearing does not spin freely, and it feels like it had a notch in it.
I took off the rubberized bearing spacer seal and the "notch" feeling disappeared under just finger pressure.
but an individual bearing/race is/has failed in it. It clinks on the road and does not spin as freely as the DS bearing with the rubberized spacer still in. The silver specs in the grease too is a red flag.
I'll be replacing the bearing on the off season but for now it will have to do. I have 3 bikes anyways. My other UT crankset has had no issues. Both bikes use outboard BSA cups and I've measured and spaced them out to specifications.
This has been a problem since day one on the brand 2018 Record crankset. Only upon crankset installation (replaced an older 102mm square BB/carbon record crank) did the clicking start. No other clicking from all the other record/sr stuff on the bike which was on for several months before the crankset. Being an aluminum frame I also refaced the shell and measured/spaced everything out accordingly.
