Visioner Prana G1 2017
The classic racing machine based on the success models Visioner C and Visioner CSL – it’s hard to imagine a better way to enter the world of the carbon racers. The Visioner Comp’s appeal not only relies on a rigorously classic visual appearance but offers the features and advantages that are typical of Storck as well. In addition to the obligatory high stiffness in the areas of the head tube and bottom bracket, both segments boast carbon elements. The cables for the brakes and the mechanical or electronic gearshifts are of course routed internally. The ‘Procycling,’ ‘Roadbike’ and ‘Tour’ bike magazines have awarded positive ratings to this bike across the board, an assessment that is particularly reassuring for first-time carbon bike riders. "Roadbike of the year 2015/16" at road.cc. The Visioner Comp makes entering the Storck carbon world an update on an all-new level.
As with every Storck bike, Marcus Storck is the leading input in design with years of experience of carbon engineering and aerodynamics
Press Fit Bottom Bracket
Press-fit bottom brackets have a number of advantages. There are no threads that might wear and make disassembly work more difficult. PressFit technology uses clearly less material and thus saves weight compared with conventional technologies. The greater bottom bracket widths provide even higher stiffness in this area and, ultimately, allow larger tire clearance. In addition, press-fit bottom brackets can compensate for technique-related manufacturing tolerances incurred with anisotropic materials (CFRP).
Larger frames, due to the rider’s weight and higher leverage, are naturally exposed to higher load changes as well. Proportional Tubing takes these loads into account. The conification, the wall thickness of the tubes and the diameter are adapted to these loads. This results in frames which, irrespective of the frame height, deliver consistently good stiffness and comfort values.
