Can you fart while pedaling?

I was having this exact same discussion with someone from wests the other day! I know I can but they too seemed to think it was impossible.

I thought this thread sounded familiar. Yes. I think we agreed the "posting" was the best option.

The most basic suspension device is the rider's legs! Experienced cyclists learn to raise themselves slightly off the saddle when riding over major bumps, keeping the knees bent, so that the leg muscles act as springs.
On longer rides, when your legs are tired, this becomes harder to do. Sometimes, too, a bump will take you by surprise. For these situations, a mechanical form of suspension can be helpful.
