It is a 29-inch QX Disc unicycle newly released by German company Qu-ax. By selecting a Q-Axle hub designed to further improve durability from Qu-ax, many gears and cranks that improve clamping force compared to the ISIS type are tightly bound with two Allen key bolts. It effectively transfers pedaling force through the use of high-strength alloy materials, making it stiffer and over 130g lighter than ISIS disc hubs.
It also comes with Shimano disc brakes mounted on an ultra-lightweight aluminum frame for softer stopping power and easier control. Based on the KrisHolm saddle, based on the advantages of a slim and comfortable sitting feeling of a bike saddle and the characteristics of a unicycle, the advantages of existing saddles are combined to create a highly reliable and comfortable QX saddle. increase.
