Managed develop a horrible grinding noise in my drive chain slightly before snapping my fixed gear chain last week whilst commuting.
Swapped it over with a new one and it's been nothing but chainsaw noises when pushing on pedals (even worse uphill). So far I've swapped the bottom bracket, tightened crank arms and crank bolts, finally swapped the chain. Yet the noise continues....
Being a poor nursing student, I can't afford to take it into a shop. Is the slight "sharking" on the cog to cause this sounds?.
Or something more serious? Whats the next step to sort this?
Thanks for any help!
