Just replaced my cassette (gone from 12-27 to 11-28) and chain but am getting a lot of noise in the 11 and 12 cogs.
50T chain ring on the front is really worn so need to get a new one. Any ideas where I can get a good price? I run Shimano 105 50/34 compact in silver.
Noise is when on either of the front rings and in 11 and 12 on the back but only when the bike's weighted. It runs fine in the stand.
Bottom bracket gone? Just seems strange that this only has happened since fitting the new cassette and chain.
I'm baffled....
