I'm fairly new to this forum but by reading some of the posts and threads theres alot of you out there that have a whealth of knowledge! I'm having trouble pinching tubes while changing tires. I thought I knew what I was doing but here lately I've been pinching 2 out of 3. I'm using the moose brand spoons with the red handles. Any tips or anything that may help me figure out what I'm doing wrong would be greatly appreciated. Maybe theres a link to a video showing a detailed tire change that somebody knows of that they could post. Thanks
