I rode CR late yesterday for the first time and had a good time overall. We started from Crim School Soccer Field, but do not remember the trail that we took overall. I did have some difficulties with my tires slipping which I could use some pointers on. I think it was combination of skills, tires (decade old tires) and tire pressure (too much pressure possibly). Plan to take care of replacing the tires with newer tires which will take care of the tire pressure also but how do I practice to improve the skills other than riding CR frequently?
