I broke 2 spokes in 2 days... I'm 6.2 and around 270 lbs.
My Specialized Crosstrail has regular Alex Z-1000, 26", single wall, 36h rims with Forged alloy, double sealed, ground race, freewheel type, QR /
After doing some research, looks like the wheels on this bike are from 20th century ... single wall, freewheel... My fault... shouldn't trust my LBS sales guy.
Is this pretty common to brake spokes while riding on perfectly flat surface?

Question is... what to do to make my wheels/spokes lasts for a long time, without spending to much $$$? What options do I have?

Thanks for any input!
