I need to get some spare tubes in case I blow some in the woods, is there any specific hd tubes u guys can speak for? And any tire spoons/levers to make Trailside tube swaps less of a nightmare? I've only had bikes with radials before and only rode street, but the adv scene is calling to me. Need to be prepared! Any advice for equipment to help facilitate Trailside repairs is appreciated as well. Thanks in advance!
Before you get involved with spare tubes, spoons, trail jacks, etc. Stop, drop, and roll: Get a bottle of Slime, and apply it to your tubes per the instructions as a preventative measure. In my experience, the majority of trailside punctures and flats can be prevented entirely with Slime (or a similar product). The best way to change a tube in the middle of the woods is not to have to.
Otherwise, tube changes will require more than just a spare tube and some spoons, and I find that usually people aren't thinking about that until it's too late...
For tube brands, anything with a brand name you recognize is probably good enough. Avoid crazy non-brand vendors. I've had decent luck with Tusk tubes, Goodyear, Double Tough (usually sold locally at Cycle Gear stores, also), Michelin, and Kenda. You can get regular thickness or the "heavy duty" type; I've never found much benefit in the ultra thick mega heavy monster duty 3, 4, 5, or 6mm tubes and these take up progressively more and more space in your kit the thicker they are. They don't actually stop punctures any better (anything that's strong and pointy enough to make it through your tire carcass will laugh at any tube of any thickness) but they cost more, weigh more, are harder to work with, and take up more room.
You also need a way to get air into the tire afterwards, like a portable pump you can connect your bike's battery. You also need a way to get the wheel in the air, especially if you have a heavy ADV bike you don't feel like lying on its side to get the axle and wheel out, and a way to bust the axle nut loose which will probably be hard to do without packing some kind of cheater bar to put on your wrench. I use the BikeMaster Lift Stick as a trail jack for my KLR, and it lives in my panniers along with my tire change stuff all the time. It's also handy for assisting with chain cleaning and lubrication on long trips, etc. Employed carefully, it can lift either the front or rear wheel.
I prefer aluminum tire spoons because they don't beat up your rim as much as steel ones, and they are not prone to being cheaply chrome plated like many steel ones also, the trouble with that being that the chrome plating flakes off and turns itself into little razor blade shards almost immediately which will obviously cause you grief. It's much easier if you develop a burr on your aluminum spoons to smooth it out on a Rock Or Something also, vs. a steel one. I have this Stockton set which doubles as a pair of axle nut wrenches. Different size kits are available, so get the one that matches the axle/nut sizes on your bike.
