If you have confirmed that there is a pull on level ground with the tires properly inflated, the next step is to swap the two front tires. If you have a pull that is generated by a tire problem, the pull will change, usually going to the opposite side.
If you have a tire pull, sometimes the tire will correct itself from running on the back for a few thousand miles (until the next rotation cycle). If it does not, the tire will need to be replaced to keep it from causing a pull.
If it is not a tire pull, the alignment must be checked. The caster and camber are not adjustable on Contiques. There are not as of yet any aftermarket companies that make a kit to provide for caster and camber adjustment. If the caster and camber is in spec, but the split (difference between right and left sides) is not optimal, you can sometimes overcome a pull by shifting the subframe. Basically you are re aiming the front wheels. There is not a lot of room there for adjustment, but often there is enough.
Generally speaking the toe adjustment will not cause a pull, but if the toe is not even from side to side, the steering wheel will not be straight and an off center steering wheel may cause the perception of a steering pull.
Don't forget that problems with the rear wheels can also contribute to a pull. If the rear toe is set so that the thrust angle (relationship to the front wheels) is off, it can cause a pull, at least in extreme cases. Sometimes a really bad tire will cause a pull even when it is on the rear. Rear camber that is way off can also contribute to a pull, but it is not adjustable so if it is found to be off, you will need to visit a frame shop.
My guess is that: 1. You don't really have a problem, it is just certain streches of road; 2. You have a slight tire pull.
Good luck with getting it resolved.
