There once was a fish from Clovis, that loaned a stand sitter a cartridge, tube and photography. The stand sitter was very appreciative of said gold fish and reimbursed him a new heavy duty tube and a couple new cartridges on the next outing.....
Any time. It's the least I could do for your first ride. Gotta help the beginners out ya know

Take the bike off the stand a few more times, gain a little more experience. You will figure it out.

of tools if you dont know how to fix most things anyways? Zip ties & duct tape. Ok...maybe a little more then that. 8/10/12 sockets,multi allen tool, an everything tool, JB quick, a lighter, snacks and sometimes a 21 tube. But honestly? I have never changed a tire in my life! I have watched many change them so if I had to I might be able to, but likely I'd pinch a few tubes.
who know how to fix things just in case. I think about all the miles I have racked up riding alone and riding in general without any MAJOR problems on the trail. I've been so damn lucky so far!!
