The riding stability and power transmission of the Di2 racer leave little to be desired. Although the integration of the electronic shifting system still seems a little provisional, the entry into the world of chip-controlled gear changes, combined with a solid carbon frame, could hardly be cheaper. The proven, stiff Citec 3000 wheels deserve praise. On the other hand, with the exception of the saddle, the components are somewhat below the usual quality level. The biggest weakness is the small selection of frame sizes, combined with large jumps between frame sizes. Thanks to the long wheelbase and neutral caster, the bike tracks extremely well even at high speeds. The slim seat post and slender seat stays provide noticeable suspension comfort on the saddle. A recommendation for heavy riders.
