Drivetrain noise

    For the last 2500 miles I’ve run an 11 speed ultegra di2 drivetrain without issue. However, the chain is too worn to continue and took the cassette with it, so I replaced both – the chain with a wipperman 11speed, the cassette with a 105 11speed. Same ratios (or as close as possible).

    The ultegra drivetrain was absolutely silent, but its replacement has a loud “glistening” sound that I can’t solve. It also doesn’t index quite as quickly, usually in the smallest cogs.

    Is this likely to be the chain, cassette, or both? I’ve done about 200 miles on them and they show no sign of quietening down. I don’t mind going back to ultegra but if there’s a simple fix I’m unaware of I’d rather try that first. Hub is a Royce ultralight, it had no spacers on the ultegra cassette and has none on the 105 either.

    I always replace chains by laying them together on the floor before I shorten the new one. This new one is the exact same length as the old.

    Change the chain. Those

    Change the chain. Those Wipperman chains are a bit basic IMO.

    People might laugh but I also reckon that Ultegra cassettes are notably quieter than 105, maybe its the machining or the finish, not sure.

    Ahem, I might have done this

    Ahem, I might have done this myself on occasion… cheeky.

    Like what guyrwood said. Just

    Like what guyrwood said. Just fixed this exact same self inflicted mechanical issue. cheeky ‘Glistening’ is not the exact word that I would of used but it is very apt and I have no poetry in my soul.

    Check the chain is threaded

    Check the chain is threaded through the rear derailleur properly. Sounds like it might be riding over part of the plate.

    “Glistening” is an unusal

    “Glistening” is an unusal word to decribe a noise. What comes to mind is excessive chain links. Did you measue the new chain against the old? And, 105’s are third tier so you are not going to get the same refinement as Ultegra or DA.
