I have a set of Bontrage Race wheels, the bike was used for 6 months when i got it, so i don't know what the storie is but i've never crashed it. THE SAME 2 SPOKES KEEP COMING LOSE. time and time again, they get to the point where it's like a peice of spagetti, but every other spoke on both sides of the rim stiff. I've had it trued twice now and the mechanic was saying we should do a rebuild to identify if there's a bend in the rim, or some bad(stretched) spokes that might need replacing. I was considering loctite, but maybe not? Is rebuilding a rear wheel really worth it ? Or should i just order a new aero wheel that i've kinda had my eye on?
