Reddit mentions of Park Tool ST-3 3-Way Socket Wrench

People make it with all kinds of gear kits, but my personal and subjective opinions are that I would consider:

• bringing waterproof shoe covers; I admit that my personal happiness perhaps more closely tied to the happiness of my feet than average, also shoes usually take a long time to dry out
  
• definitely keeping the 20000mAh powerbank (someone suggested 5k), I have the same one and especially if you're using your phone for nav you can go through it. you probably know this but that sucker takes like 8 hours to recharge, so just plan on that being an overnight thing not a stop-at-a-cafe thing.
  
• take vulcanizing patches instead of Park. The Parks are fast but I've found them less reliable
  
• lean towards just using a rain jacket for wind conditions. Or maybe bring a wind vest, I got one of those recently-ish and it rolls up so small. The main downside to using rain jacket for wind is it doesn't breathe, can get to warm and sweaty, but whatevs
  
• put my computer in a separate lightweight drybag - redundancy of protection for critical item
  
• bring something so you can have something warm on your head and your neck (not sure which the Buff was intended for). Per unit mass, I think my fleece neckwarmer is one of the best items I have. Yeah, it's July, but you have to imagine you get a mechanical issue on a pass. Also, downhills. Arm warmers also very warm for the weight
  
• If you have a kitchen scale and an extra hour: weigh everything, put it in a spreadsheet, and sort by weight. It seems OCD, and I swear I'm not really that OCD and felt ridiculous doing it, but it was really helpful to put things in perspective as to what items were worth leaving at home due to weight and which just didn't matter compared to my overall packed weight
  
• bring a smaller adjustable wrench, or no adjustable wrench at all. do you have bolt-on wheels or seat tube that require that? if it's for replacing cables . . . you probably could do with a mini-version or a Park ST-3 or similar hand socket wrench. A drive-side rear spoke break seems like a sufficiently rare condition, and a full-size adjustable wrench is a sufficiently common tool, that you could probably just borrow one in that circumstance
  
• I've found webbing-with-clip more secure than bungees for most applications, lost a down jacket once that was bungeed to a bike
  
• bringing lip balm, not mentioned in toiletries
  
• extra rack/bottle cage bolt or two, had one of those come off on me once and was very happy to have a spare
  
• bring extra spokes that are the right type/length for your bike's wheels (which often means three lengths: front, rear drive, rear non-drive), can tape those inside seatpost
  
  ok that's a long list I'll stop now
