If you've got a suspension fork then my guess is you won't have any rack eyelets on the foot of the fork or mid-way up. I don't think Tubus make an axle mounting for their lowriders so unfortunately Tubus lowriders may not be an option. You should not even consider fixing a lowrider entirely with p-clips or hose clamps. The Tubus Swing is intended for suspension forks, but is not a lowrider. Panniers sit high up on the wheel on the Swing. Maybe it works, but I just don't like the look of it.
OMM are probably the best option. They make both a lowrider and a rack for the front that attaches via brake bosses and the axle. Expensive but extremely well made.
Tubus racks of course have the advantage that they're made from steel and so are more easily repairable. I have had to repair a Tubus rack, but never an OMM rack (I use an OMM Sherpa front rack).
