Spokes keep on breaking
 
I've done research on the forums other people have it. But basically I'm wondering WHY does it happen. I weigh 300 pounds. The bike Igot was a trek 3700 disc..and I replaced the back tire. I told the LBS to gimme a bette tire because I kept on brak spokes. So he came me



But every two weeks it keep on poppig

Need stronger wheels. With that weight go 36 spokes

Yep, the wheels that come on that bike are made to handle minimal abuse. You're gonna need some stronger double wall rims.

Breaking spokes indicates that as the wheel rotates, the spoke at the bottom is completely losing tension, causing flex that eventually causes fatigue failure.
Solutions:
a) Higher spoke tension. If the spokes are already ~110Kgf, going higher may result in rims cracking around the spoke holes.
b) More spokes.

You need a better wheel...

Sorry the rims I got was Mach1 Type XC 210.
That is the one he got me.

I'll suggest you lose some weight.

^Better rims will help you lose weight if it makes you ride more

I am losing weight. But constantly every 2 weeks my spokes keep on breaking. I lost 30LBS this summer. What should I tell the LBS.

Is it just the rear wheel, or both?

200 lbs is considered heavy in cycing terms, let alone 300lbs. You may just have to get a tough wheelset built up. If your LBS can't do it try another.

Also - I had a similar problem once, the rear wheels kept breaking spokes, even though I wasn't doing anything rough. Turns out the back derailleur was bent inwards, and would smash into spokes when I was on the lowest gear of my cassette. Make sure it's not that before you sink money into better wheels that you'll just break again.

You need the toughest, most advanced wheel set available
