Elite's Fluid Primo Elasto-Gel Trainer features a new quick mount support stand, new resistance fluid unit and larger (45mm) resistance Elasto-Gel roller. This new folding support stand allows the rider to actually feel like the bike is on the road with more flex than any other support stand. Elasto-Gel resistance roller decreases noise, increases tire life and increases the grip between the roller and tire offering the feeling of a real-road ride. The sealed hydrodynamic system regulates the effort of the pedalling through a rotor submerged in oil with special characteristics of viscosity and high temperature resistance. System’s rotation speed determines the effort, more or less intense that is transmitted to the wheel. Everything happens inside an aluminium alloy housing, with wide cooling fins for a quick heat squandering. Team Cyclist is an authorized Elite dealer and will honor all manufacturer warranties.
