Bicycle Mechanics - "Dirt drops"

I've been considering fitting my old Saracen rigid MTB with drop handlebars, as part of a conversion to make it more useable as a 'cross bike, but I'm confused about the bars. I've seen several sets of bars labeled as "dirt drops", but what's the difference between them and regular drops? Is it simply that regular drops aren't as strong? Since I'm hoping to keep the bike useable as an MTB as well as a 'crosser, is strength likely to be an issue?

Thanks in advance

dirt drops are drop bars that are extra wide with flaring at the ends.
They're meant to be used in the drop position only, unlike road drop bars which offer at least 3 positions.

They need to be placed higher up than regular flat bars, because of their drop and position you get with them.

these are dirt drops.

Ah, so there's actually a difference, it certainly seems worth looking into. With regards to strength, if I do go for conventional drops, am I likely to break them riding cyclocross or light XC? Nice bike, by the way.

the drop part of the bend is often flared, also .. a non heat treated bar can be pried outward .
thats the source of the original WTB Dirt drop, i think a Cinelli 64 was modified

On One and Soma offer a variation.. I have Nitto bars made for equipping MB1s ,
the drop flare also get the bar end shifter out of normal Knee contact.
I put some shop take offs, on my Road bike .. with bare con shifters.

thicker tube and heat treatment ruggeds them up..

Are You likely to break them ? Do much soil sampling when you ride?

all bars can be broken, but that's rare.

It might be worth your time to contact your local race organizers. Dirt drops aren't allowed in 'cross races around here (too wide, I was told).

That's a great looking commuter, AEO.

Not a bad idea, actually, I might try it, I found them on a UK website as well. I wonder if they'll take brake levers....
