Hi All,
I'm new here and would like to throw this one out there. I ride a GT Aggressor Sport 2019 MTB which recently needed a new bottom bracket. There may be no connection but since the replacement I've had an intermittent non-metallic knocking sound which seems to be coming from the back wheel? It happens when I pedal in a higher gear ie. the 6th and 7th rear cogs and the middle and higher front chain wheel. I removed all the accessories (mudguards, rear light, tool kit) but the knocking persisted. The rear wheel cassette is not loose and I have adjusted the limiting screws on the front derailleur so they are not touching the chain. This is infuriating as it can happen at the start, middle or end of my ride. Any similar experiences or explanations? Many Thanks.
