As riders get in better shape and lose weight by cycling, many then start buying lighter and more efficient equipment.
Should not a rider that is in great shape try to get the heaviest and largest tires which have the greatest rolling friction, so that they can continue to get the most exercise out of their ride.
Well going faster with all this new high performance equipment might sound good but remember that the amount of road rash increases as the speed is cubed. So twice the speed equals 8 times the road rash.
I am only kidding. I think that the new equipment inspires the rider to reach even higher goals.
Ride long and strong and be safe.
