I used to get bmx plus magazine when I was a kid and they always had the coolest tips and tricks section. I used alot of them. One time when I was older I was on mountain bike trip and I got a flat tire. I usually kept a spare tube in my little seat pouch but i had used it the week before so i was screwed. I remembered a trick from bmx plus and made it home. You pull the tire half off start stuffing leaves or ferns or anything you can in there and toss the tire back on and use zip ties or I used electrical tape and wrap the shit out of the tire around the rim. Worked so good. Got me out of a logging trail 5 miles in the woods. This one isnt really a road side repair but a cool hack. So when installing new cables you always try and cut them so they wont Frey. I always wrap with a little tape cut them off and then take an old bicycle spoke nipple and crimp it on the end. Looks like one of these nice fancy cable end things. (edited)
