Any question answered...

I've got a great opportunity to buy a barely used mountain bike for cheap (ish).
I'm 6ft 1 and the bike is a rockhopper in XL.
A lot of conflicting advice regarding sizing.
Some saying get large or even medium! Others saying it's more about reach these days and get as big a frame as you can comfortably stand over.
I'll be trying the bike regardless, but what should I be looking out for?
Apparently the XL bike is for people of my height and above.

It's very much personal preference, but I'm 5'11" and always felt best on a medium. Obviously body sizes differ so two people the same height may well feel comfortable on different sized frames. Also no idea how consistent sizing is between brands. Have you ridden a similar frame before and if so is the size roughly in that ballpark?

Dropper posts. You’ll want one. If the frames too big, you’ll not be able to get a decent length dropper post in it for your saddle height.

Cheers.
How much length should I be looking to leave?

Dropper posts. You’ll want one.

Maybe. I've somehow managed to MTB for 20 years without one.

@Brum I'm your height and if I were buying a current generation Rockhopper I'd get the large

Cheers. That's what I'm thinking. Maybe have to leave this opportunity to someone else.

You have to embrace change. Just as you did when pneumatic tyres were invented ;)

Next you'll be telling me variable gears are something more than a passing fad 🙂

I'm sure droppers are good for some types of riding, but I'm equally sure that, like any of the other fashionable technologies, most of the people who have them don't need them.

It's literally impossible to ride an MTB without a dropper.

Can someone explain crystals for me? Just been to a crystals shop with my kids. They’re ooh-ing and aah-ing but to me it just feel like a massive scam.

You've already explained it to yourself.

There's an aesthetic quality to crystals which gives them a value to people, sometimes a very high value when more than one person wants the same rare example https://www.bbc.co.uk/news/world-asia-39486749

There are plenty online convertors

I get the pretty-ness, but the whole “this will give you inner peace, better pay and a bigger dick” nonsense that is written on a small note next to each stone.

Imagine if the stones actually had certain qualities. The shop we were in would be a fucking tornado of energies.

Needless to say my kids didn’t get any magic stones.

So apparently there'll be a chronic shortage of lithium by 2025. What's going to happen to EV manufacturing? Will synthetic petrol save the day? Is synthetic petrol really carbon neutral and sustainable? https://www.evo.co.uk/fuels/205634/synthetic-v-regular-fuel-sustainable-petrol-put-to-the-test My head hurts today (brain fog from ME/CFS) so I'd love it if someone could explain it all simply.

There are 1.3 bn petrol/diesel vehicles on the road, and the number is growing because cheap Chinese motorbikes are giving people in developing countries their first chance to use motor transport. https://www.telegraph.co.uk/global-health/climate-and-people/togo-accidents/

“this will give you inner peace, better pay and a bigger dick”

That kind of bullshit relies on more or less the same delusional "thinking" as homoeopathy

So apparently there'll be a chronic shortage of lithium by 2025. What's going to happen to EV manufacturing?

A few different things (non-exhaustive list)

• End of life Lithium batteries will be mined for lithium, since dead batteries are about as lithium rich as good ore deposits but don't need digging
  
• "Shortage" of an abundant element like lithium just means the same as price, as rich ores are worked out the price goes up making poorer ores economical. There is more than enough lithium in the crustal rocks for any conceivable EV needs, including aviation and shipping, as long as people want it enough to pay for it
  
• Alternative battery technologies using much more abundant elements as the charge carrier (sodium, calcium) could replace or complement lithium. Currently lithium is favoured for high energy density, but even if other technologies fail to match it they might become so much cheaper that lithium will only be for Ferraris and aircraft, and everyday vehicles will use the cheap but heavy option
  
• If batteries get either expensive or heavy, hydrogen (fuel cell or internal combustion) will be more competitive. Fully synthetic liquid hydrocarbons are as carbon neutral and sustainable as hydrogen, but may be too expensive to offset the cheaper infrastructure, and liquid hydrocarbon road fuel infrastructure might have vanished before that gets tested
  

Thank you! Plus there's wireless charging, from pads in the road. You can charge as you drive, which means you can get away with a smaller battery. https://www.ft.com/content/2401d64e-f23e-48a6-9a0b-9ee5d777e5e4
