Never heard of or seen a Tout Terrain, the below pics and info are from here: http://www.peterwhitecycles.com/tout-terrain.asp Pretty cool but if you can't deal with asymetrical design better not look.

On the top you see a front view of the Silkroad fork. The blade on the left, which is actually the right blade, is thinner at the top. The blade you see on the right of the top photo, the left blade, is thicker at the top to compensate for the twisting action of the disc brake, which is attached to that fork blade. Looking at the photo on the bottom, you see the same fork, but now looking at it from behind. Now you see the left blade with the disc brake mount near the bottom, just above the dropout. On the back side of the right fork blade you see the three wire holders for the lighting system. A hub dynamo has its connectors on the right side. So the wires from the hub run up the back side of the right fork blade to the headlight mounted either at the fork crown or further up on the handlebar. The connector on the upper part of the left blade is for the disc brake line or cable housing.

The Silkroad fork is designed from the ground up as a disc brake fork. It's asymmetrical to eliminate torque steer from the disc brake. The left blade is much stiffer than the right blade. The dropouts face forward so that the action of the disc brake pulls the hub into the dropout.
