Any question answered...

Is it a bad idea to run a 2" tire on a 19mm internal-width rim? And if it's fine, would that mean the actual measured width would probably be a bit less than 2"?

Not ideal, but probably fine.

Do I actually need it

No

Plenty of us ran mtb tyres on skinny rims in the 80s/90s and didn't die.

Classic survivorship bias.

You could always ask the tyre manufacturer:

Ah awesome, thank you

Hah, rep!

Nikon D3500 SLR camera any good?

Depends what you're using it for. You can get a mirrorless Sony A6000 for similar price.

Seen one ......as new ... £300-350. Are mirror less better?

I think so. Better autofocus, higher fps if you like action shots etc. Depends a lot on intended use. They're also smaller and lighter.

I’m looking for replacement sealed ball bearings for a buggy (babyzen yoyo) and am struggling to find the right fit. They are almost standard sized 6900.
10x22x6mm, but the inner race extends an extra 1mm on each side.

So, assuming I can’t find a supplier of the proprietary bearings, where can I get M10 washers 1mm thick that have a small enough OD to avoid fouling the outer bearing race?

Chainring spacers should work

Bingo, of course! Thanks

Can anyone confirm whether a PopSocket will stick to an Otterbox Commuter?

Got a new laptop for the child. Assumed it would connect to a monitor, but it only has USB3 and miniHD ports. Can either of these be used to connect to hdmi/scart?

Edit. Yes.

Scart, such an unattractive word

Does anyone live in Ruskin park house or know someone who does? I have a question...

Is that the one with a swimming pool? I don't but I looked at a studio flat there years ago.

Are tubeless tyres much more difficult to install on non tubeless rims compared to non tubeless tyres on non tubeless rims?

I've just got a g-one to test with my deep drop brakes and it was impossible to fit!!!

Yes

@howard thanks, that's a pain!

Muc off is your friend.

EDIT: problem sorted.
