Once, at the start of an organized ride, I noticed a fellow who had all of the appropriate gear but, there's no nice way to say this, he was fat. I'm sure that he outweighed me by at least 100 pounds and I'm a bit on the pudgy side myself. Then I found out that he was a hairdresser - a WOMENS hairdresser. I thought to myself "He's gonna be off the back real soon."
Do I even have to say what happened? We took off and I watched that big butt slooowly pull away from me until it disappeared into the distance. I've avoided making judgements based upon "kit" ever since.
It's the motor. Some guys have real good ones and some of us don't.
