>>1793966I feel like this is a troll but in case it's not: that's a shock pump. You *can* inflate a tire with it but it will you a very long time since it's meant for a low volume, high pressure application.
>>1793971If your wheel is slightly out of true by that little it's not really concerning on its own. What would be more concerning is if it was out of true because the spoke tension was uneven - squeeze pairs of spokes and see if you can find any that are appreciably loose or stiff, and if so your wheel needs truing, if not it's fine.
>>1794062Sounds like a worn quick link, they should click closed, otherwise it's time for a replacement. Even the easiest of all quicklinks (Wippermann) should require some pressure to open.
>>1794178Similarly I've owned multiple leather saddles but don't notice a comfort difference between them and modern material saddles when the shape of each is correct for me. If you didn't have easy access to different saddles to try then leather would have the advantage that its shape does slightly conform over time, so you could get away with starting with something that was a 95/100 fit and over time it would become a 100/10, but if you can get a 100/100 fit right out of the box with a lighter modern saddle that doesn't also tend to sag over time then there's no reason to go for leather IMHO. In the distant past leather saddles really were the best option available, but these days the only reason to go with leather is because they look the part on certain bikes.
