I'm having difficulty comprehending the notion that anyone who wasn’t being followed by a team car doesn't know how to carry out the basic on-the-road maintenance that we all know and love hate. Got new tech on your bike? RTFM, like this Unit did with hydraulic rim brakes thirty years ago and hydraulic discs shortly after the turn of the millennium.
Oh you'd be amazed.
When I was at the shop recently a guy came in. He had an e-bike, and the rear tyre had gone flat. He'd tried to ride it a bit further to the shop, but the tyre came off the rim, and the tube popped out. He kept riding, the tube self destructed. He kept riding. When he pulled up at the bike shop we looked at the rear wheel, we looked at each other, we apologised, then told him it was going to need a new rim. If he'd walked it slowly to the shop, it would have been inner + possibly outer. In the end if cost him inner, outer, rim, and wheel build.
People don't understand bikes.
You'd be amazed at how many people who ride even high end fancy bikes aren't able to fix a basic flat at the side of the road. What's worse is the number who inspired by "being more pro" have a crappy multi tool, a single tyre leaver, and a pump that wouldn't blow out a candle, but fits in their jersey pocket. I have rescued many a roadie at the side of the road by simply having a decent pump (Topeak Turbo Morph G -

So what was her plan if she had a puncture? Taxi?
Changing pads is a different matter - they are unlikely to wear out completely on even a long ride, so you could take them to the bike shop. Or learn on youtube - you need a bike shop or the internet to get replacements anyway.
Really? There's two sets in my frame bag, just incase. They weigh nothing, and the tools to swap them are a 3mm allen key, and my leatherman...
There are so many standards for disc brake pads that to hope that the next bike shop you goto has the right ones is asking a bit much, simpler just to carry them in your bag... not like they are heavy.
