The super-quiet, hydrodynamic Qubo Fluid has a resistance unit that is 100% more powerful than a conventional fluid resistance unit. This is achieved by a large flywheel completely immersed in oil. This enables an automatic increase of the resistance with increasing speed and thus a higher load of the brake unit. This allows you to regulate the resistance simply via the gearshift on the bike. The frame of the Qubo adapts directly to the weight of the cyclist, his movements and the size of the bike thanks to the exclusive Crono compass system. Similar to on the road, the energy is transferred differently to the roller trainer and affects the power output generated at the same speed. The high-quality frame consists of an innovative steel-plastic construction and is therefore particularly stable. The enlarged diameter Elastogel roller (45mm) reduces the wear of the tyre by 20% and the noise level by 50%. The newly developed Fast-Fixing fastening mechanism enables the rear wheel to be installed quickly and easily on the exercise bike in just one step. All Elite castors are pre-assembled and absolutely simple to use. The training can be started after only a few minutes. When the workout is finished, the fluid can easily be folded back together again. Suitable for all wheel sizes from 20 - 29 inches.
