Looking for some new pedals to replace a set of worn shimano DX.
A friend has mentioned that as my frame is boost then I need some pedals with a wider axle to compensate?
Is he right?
Yes and, if it's a 29er, you'll need a specific saddle too.
No
Correct. 29er specific saddle here

Very hard to come by, but I have some that I could let you have for the right price 😁
Sort of. Q factors (distance between the end of cranks) since boost came along have increased each year and now have stabilised at 'boost' wide, however if you have a boost rear end and older cranks you might find wider q factor pedals help with heel clipping/rub, but their not called boost, just wider q factor. So while your mate is probably trolling you he is also right, kind of.
Burgtec do "boost" axles for their pedals, but nothing to do with boost cranks/ hubs, they just move the pedal further from the crank
You need boost if you want to go up to 11.
It sounds like you need a new bike 🤔
Just buy two of these and melt them on to your existing pedals. Job jobbed.

The std burgtec pedals have a very narrow q factor so there new addition is more in line with what every one else does .
I personally like a wider q factor for better stability but it's personal preference
Boost Pedals
Quick, someone patent that before SRAM, Trek or Spesh do. And metric chains.
And metric chains
Been done. About 40 years ago.

Didnt stop SRAM patenting narrow wide.
I was thinking about chains the other day, if you did make a 'metric' chain with 20mm pitch rather than 1" you could reclaim the 11t sprocket (or even make it 12) and reduce cassette wear.
But more links wearing at the same rate would mean chains appeared to stretch quicker. So it might happen if someone could develop a significantly harder chain.

Would they wear at the same rate if the force is spread across more teeth/pins?

In theory yes, in reality the chain only properly engages with one tooth at a time once it's worn even the slightest. But then in that case it's engaged for less time so maybe?
I'm sure it's something SRAM/shimano have tried when shrinking cassettes and free hubs.
Wouldn't cassettes be absolutely massive with 20mm pitch? Surely the rear mech would drag on the ground too?

And is the bike on a treadmill facing into the wind?
edit- I think he meant 10mm pitch, not 20mm.

There patent would of related to the application of the technology than the technology itself.
You can get axle/spindle extenders but your crank clearance would be the same width
