How do you know it's the BB getting loose? Do the crank arms rock side-to-side a bit? I've had BB's "click", BB's "grind" like shaking coffee beans, and BB's simply have seized. But rarely a "squeak." Most of the squeaking in that area comes from chain, crankset, and pedals. So I'm curious why you'd want to tighten the BB and why it would be coming loose on your bikes. Is it a chronic problem?
