Think about what you might need on your trip, even if you think it won’t be difficult to buy tubes or common parts, it can still be a hassle to find the right shop and it also takes precious time from your holiday or and training time. Also, consider specific parts that are not so common, such as: rear derailleur hangers, shock bolt etc. You will need a small pump, shock pump, all the tools to build your bike and a multi tool, chain lube, gorilla tape, zip ties and your center lock tool if needed. Make sure to take sample size or small bottles with you, those are always a good idea as some security screenings may mean you have to throw larger containers away at check in. Don’t forget bottles and energy boosters - always double bag powders as it’s a messy job if one bursts!
