I ride a hybrid with riser handlebars. There are a lot of oak nuts on the ground at the time of the year now. Each ride pass sounds like a chain of firecrackers popping crushing the nuts. I grip the handlebars so tight, because I am afraid of the tires possibly being turned ( I had a few accidents because of hitting a little tiny rock which caused the tire to turn). Should I grip the handlebars so tight??? Or should I just grip it firm but not tight like usual?
