So for the third time this month, I've snapped a rear spoke. It's always the spoke connected at the drive side, right at the spoke head bend. The rims are Alexrims ID19, 32 hole.

I've had the spokes replaced for free where the bike was purchased at Performance Bike. They mentioned after the third one they'll look into a warranty replacement. They feel it may be a defective rim or hub. I dunno.

Will it matter though? I'm 250 lbs. Is this wheel too weak for me? Do I need to look into something substantially stronger? I've been riding this bike since I was a heftier 280 lbs. and haven't had any problems until recently.
