Noisy Chainset on Cannondale Tandem
We have a Cannondale offroad tandem from circa 2010. I find the chainset noisy when compared to our other tandem which is a PedalPower Classic Steel with Rohloff Hub. The noise is coming from the timing chain or the bottom brackets. On our PedalPower the timing chainset is almost silent but the Cannondale is a constant tinny purr. Ok, so I thought the the chanrings might be not compatible with the chain, but the teeth never catch on the chain links or so it seems to me. It all runs smoothly but with noise.
Anz ideas what I can do?
