The lighter you are the faster you get through tough terrain.blastguardgear said:Well, a light bike is good for people that like to do all those crazy bike tricks. But the body weight is important if you're one that rides tough terrain and harsh elements. You'd need to be heavier then.
Modern clothing is a wonderful thing. No need to stay fat like a seal in order to keep warm when a good jacket that weighs a few ounces will do the job better.
If you fall off, being fat or muscly isn't gonna help you stop breaking a collarbone or getting other injuries. The extra weight may even play against you. 180lbs hitting the deck or 145lbs. I know which id rather be. I've been both an life is better at 145lbs.
