Yes this “bottom bracket noises” happen to everyone, every bike and groupset… It has happened to me several times the last 7 years, and I managed to fix it every time… not this time though.
This is the thing: it only creaks when I am on the small ring when putting pressure on the pedals (250w+).
It creaks on every part of the cassette, with another chain, standing up or sitting down, with or without bike shoes… and as soon as I put the big ring on, the sound stops altogether.
If I had to describe the noise, it sounds like when you try to pronounce the letter R in spanish, only when pressure is being put on the pedals (downward stroke): rrrr, rrrr, rrrr…
I already dissasembled the BB twice, greased it all again, made sure the torque is right, changed the chain, regreased the cassette in and out, changed pedals just in case… I am out of ideas.
Has anyone heard of something like this? I feel that because it ONLY creaks when in the small ring, it crosses out many other common things, but I just don´t know what else to do.
