I have a squeak from somewhere on the right side in front of me but only when turning right. Speed does not change the sound so I have ruled out wheels, bearings, tranny etc. I have shaken and pushed and pulled everything on the bike but cannot recreate the squeak, I f'n hate squeaks!
Anyone?

 

Possible cause which took me 2 years to locate on mine is the seat tab rubbing on frame. wrapping with electrical tape was the cure! Good luck
