I bought a new 27 speed Shimano 105 bike this year. Up to now I haven't been serious and have been riding a Schwinn 10 speed around the neighborhood. I've trued my wheels in the past, since I was a "kid" and I've gotten pretty good at it. BUT how do you determine how tight the spokes should be? I've always tap them with a screwdriver and expect to hear a ping rather than a clud. Other than buying a tensioner, is this a satisfactory way? On my new bike, should I use this tapping method to check for spoke tension? and then if it clunks, tighten it? A previous post said under tension spokes break.
