Pi Rope brought a breath of fresh air to wheel construction around six years ago with its flexible but tensile textile spokes. How do the lightweight 1192 gram Pi Rope Duke Lucky Jack SLS4 with Vectran spokes fare in the wheel test?
At 2589 euros, the Pi-Rope Duke wheels are the most expensive in the test and, thanks to the lightweight textile spokes, weigh less than 1200 grams. On the other hand, the Duke rim with a rim width of 28 millimetres is slightly narrower than that of the competition. The majority of suppliers rely on a rim width of 30 millimetres, even for cross-country use.
With the very low rotating mass, the Pi Rope wheels get going effortlessly. The lateral stiffness is low, as usual from other tests. Comfort and damping were praised in the ride test. The Pi Rope wheels are very forgiving, generate a lot of grip and are easy on the rider. Some riders found the feedback too indirect. The beautifully finished rims offer good protection against punctures.
