>>1813988No, there's not. Check your tire pressure before every ride - you don't necessarily need to check with a gauge/pump each, just shift your weight over each wheel and look at how much the tire deflates, that will give you a rough estimate of whether more pressure is needed or not.
>>1813984Issue probably has nothing to do with tilt then, it's more likely that you have a saddle that's too narrow/wide for your sitbones and posture.
>>1813990So much wrong here: not all saddles are meant to be perfectly flat, and that's just one aspect of proper fit. Recommending saddles by brand is pointless since they all make multiple options. Saddles should be comfy without a padded chamois - these help with chafing and comfort but don't magically solve problems caused by a saddle that's the wrong shape for the rider. And no, insoles solve a different set of problems, they're definitely not a panacea for saddle issues.
>>1813983Get any bag with handles and use those to tie it to your bars. Or get any basket you like and attach with clamps or ties - just keep in mind that this should only be for carrying light items.
>>1813982Are you stuck with 6-speed for some reason? They're all basically the same and you've included discontinued models in your list. Megarange is fine if you're someone needs a really low bailout gear, but will always give clunky and slow shifting since the gap to that last sprocket is huge.
