If you can notice the crack, it is simpl;y waiting until you get as far from help as you ever get before it bites a hole in the tube . . . .
There are torque wrenches made for spokes, and, in theory, tightening them all to the same value SHOULD result in a round wheel . . ..
given that the wheel needs to be round, and some are offset to one side or the other, and also taking into consideration my comeplte and utter failure at successfully getting either of these things right the only time I really tried . . . . .I take it to the shop.
let us know how it goes, pleaseandthankyou!
