Get by without a torque wrench?
I see that most of the parts I've been buying have torque specs with them, and I was wondering if it was important to get a torque wrench. When building my bike, my LBS will be installing the BB and headset, I'm going to give everything else a go. Since I'm new to this, and completely unaware of the tolerances of most parts, a torque wrench seems like a good idea. But I do think I've got a bit of common sense, and if that is enough, I'd be happy saving the cash (as long as I'm saving cash, and not about to destroy an expensive part).
Sorry, forgot to search first, for anyone else looking for a discussion on this:
