Bottom bracket problems?jnapoli

what are the first tell tale signs of bottom bracket wear? When I stand up and climb I get a clicking sound, and I feel some vibration when I spin.Is this caused by the bottom braket?

If you feel BB roughness when riding, the thing is really shot. However, it is much more likely that the clicking is caused by not enough grease and torque when installing the BB. Time to take it out, clean and grease the threads (on the frame and the BB), and put it back together with the full 50 nm of torque as specified. That will probably eliminate the click. While it is apart, you can turn the BB axle by hand to feel if there's roughness. Wiggle it to see if there's play (looseness). I'm betting what you feel when you spin is a dirty/poorly lubed/worn chain.
