2 questions. 1 How long or should I say roughly how many miles will a average bottom bracket last? The only info I can give you is its a shimano (Ridgeback Velocity 08). 2 Whats the best way to check for wear? The reason I am asking is of late I can feel a very slight clunk through the pedal, I have checked for any play and it feels solid. Its has done around 2000 miles on road since last August. My other thought was the chain but measuring it seems to be ok and I keep it in good condition. Any idea's?
