So how does it work? Well, a suspension fork (spoke suspension) only works on one plane. The Loopwheels on the other hand, provide what Loopwheels call, “tangential suspension.” Basically, they work in every direction, according to Loopwheels.com. So, they respond “to a force hit head-on in the same way as they do to a force from above or below.” This gives riders a smooth ride, instead of the lumpy, vibrating ride they are used to.
Suspension Wheels Loopwheel & Softwheel Home Parts & Accessories Accessories Suspension Wheels SoftWheel state that their wheel's innovative in-wheel suspension technology can help reduce pain and provide a more comfortable ride. 3 suspension arms are built inside the wheel and automatically compress when encountering an obstacle or rough terrain, but remain rigid and strong over flat surfaces The arms are set equidistant around a central hub to provide shock absorption - no matter what the angle of impact is. The suspension arms immediately reset and return the wheelchair – and rider, to a level ride.

Loopwheels give you a smoother ride. They are more comfortable than standard wheels: the carbon springs absorb tiring vibration, as well as bumps and shocks. They’re designed for everyday use and are strong and durable. They won’t run as true as a spoked wheel, but they will be a lot more comfortable. Loopwheels are not just a wheel, they’re a suspension system. Loopwheels help people push over uneven streets, rough tracks and gravel paths, with less effort, and the carbon springs give you extra power to get up or down kerbs. They reduce jolting and vibration, by as much as two thirds compared with a spoked wheel. Users report that this helps them manage pain. With standard quick release axles, a choice between 12mm or ½ inch bearings and available in 24″ and 25″ sizes, loopwheels fit most manual wheelchairs.

I bought a pair of loop wheels a couple a years ago, unless they have improved, i found they bend from side to side. After spending a lot of money on them, i returned to my spocked wheels. So far there is nothing to beat the spocked tried and most successful design. the best suspension i found is seat post suspension and front faulk suspension.
