Relax Your Grip to Dump Heat Through the Hands

“If you're bicycling on a hot day, you don't want to be grabbing your handlebars all the time. You want to periodically. ... if you're cycling and you're working hard and you want to be able to do more work... gripping the handlebars too tightly will actually limit your performance”
