Look, I know what you're thinking. "These belts are too expensive." Maybe there are cheaper ones on Amazon. Hold on there, partner. From experience, cheap belts don't last. They stretch. They break. These here are re-enforced belts made to withstand the torque of carrying around your fat ass. You'll save money buying these. And if they break, have a look at your drive gears and make sure the teeth aren't sharp. If they are, you need new gears AND belts. So, yeah. Buy these.
