After my ride, I changed clothes and found that my cycling tights got scratched -- 3cm in diameter. I was really surprised and didn't know why at first. Later I realized it's because of the velcro strip of my saddle bag. That strip (with hooks) wasn't sealed properly and apparently it scratched my right inner tight through my pedaling.

I just wear this Cannondale for about three times only. I have spent too much on bicycle stuff recently (clothing, shoes, pedals, trainers etc), so I don't expect to buy new cycling tights any soon. If I still wear this pair, will I face the same situation like this thread "My shorts gave my friend a good laugh today"?

Another new lesson learned. Not cheap though.
