whats the difference between a dirt, street, and flatland forks

dirt and street forks are usually tougher so they can take abuse, which means they usually weigh more. flatland forks don't need to be too tough (flatlanders work on the ground not high in the air) meaning they can weigh less, even though some don't anyway... but they also have 990 brake mounts on them. (obviously allowing the use of front brakes)

i also heard flatland forks r shaped a little differently?????

Flat forks will usually have less wheel offset, so the wheel is more in line with the fork than with street & dirt forks which will have rake.

Dirt forks typically are a little lighter than street forks and will definitely not have 990 mounts on them.

Street forks will be built toughest of all and will usually have the option for 990 mounts as many street guys actually use their brakes and work the front wheel out there.

Flat forks will usually have less wheel offset, so the wheel is more in line with the fork than with street & dirt forks which will have rake.

Doesn't Odyessy's Pro Dirt forks have the option for 990 mounts? I thought they did. I don't know, could be a mistake.

It's not like it's written in stone. And if you're not sure, why dont you look it up and be sure?

Well he said: "....and will definetly not have 990 mounts on them." So that is why I asked because I thought that Odyssey's Pro Dirt forks came with or without brake bosses. Well I just checked this morning, and everyone of their forks have the option for 990 brake bosses EXCEPT their Pro Race fork. So maybe their Pro Dirt fork is their street fork and they just named it that way, I don't know. But it does have the option for 990 brake bosses, and that I DO know. But oh well, it doesn't really matter, and it really isn't worth getting into an arguement about.

I wasnt arguing, just telling you to look it up. That's very possible. alot of my friends use dirt forks for street.... Most ride brakeless, but ya know..

There is no real difference between a fork for a dirt and a fork for street; the real difference used to be that street forks had peg bosses, but seeing as how no one uses peg bosses anymore, there is no difference.

Odyssey doesn't have a street fork.

Dirt, racing, flatland. They also have a non 41-thermal fork which is similar to their dirt fork.

If I were going to classify a fork as dirt though it would be similar to a racing fork, but slightly stronger, perhaps thinner dropouts. A street fork I would give thicker dropouts and would build like a tank and have the option for 990 mounts.

Odyssey doesn't make a distinction with a street fork, just dirt, race, flat.

Oh, and in my world dirt forks wouldn't come in 14mm as there is no grinding, and often not even pegs in dirt.

Street is all about 14mm (if you are hard on the front axle (beerman)) and serious strength for the 12 foot gap to icepick chunk on granite.

Correction: Odyssey had a street/vert fork up until last year. The only difference between it and their dirt fork was that it had peg bosses.
