Got a rattle coming from the chainring area, I suspect it might be due to the chainline. I have a claris crankset with a tiagra bottom bracket and claris 8 speed cassette. No spacers on the bottom bracket.
The bike came with a feimin 68mm BB (FP-B902-2J) and prowheel crankset. Noise started after replacing these. There's no rattle when chain is off and cranks spinning.
