I have the delight of being able to present the current (fully spec'ed) world record bike of GÃ¼nter Mai
, weighting in at a scant 3,195g.
The bike had been presented back at last year's Eurobike in the beginning of September at the GermanCarbonGroup
booth and by now [Feb. 2008] already came to see 12,500 road km, which should be proof enough of its usability & reliability. It had also been featured in last month's issue of German Tour-Magazin.
GÃ¼nter, who has already been known for his extremely light and highly tuned bikes for over a decade, has once again been pulling out all stops in the quest to top his previous 3.5kg world record Scott CR1. As with everything borderline, the more you approach the limit the harder it gets and the more efforts and creative thinking it needs to shave some further tenths of grams - especially since GÃ¼nter's projects are not only about building the absolute lightest bike any
possible, but just as well about optimizing the performance whilst above all maintaining the reliability for everyday riding. With this vision in mind GÃ¼nter has been spending endless hours in his workshop & with tests out on the road, dedicating himself to the smallest bits, trimming down all the metal parts on his lathe, or rebuilding complete components in carbon. As a result there probably is not one single part or bolt that has not been fine-tuned. Due to his long-time presence & reputation in the scene, both as ambitious tuner but also committed cyclist, GÃ¼nter also reaped the support of some of the best reputed tuning companies who most often see him as the perfect platform to test new parts prior to their release. Complete part lines such as Tune's Skyline series have directly evolved from his projects. Like that many of the used parts are one-offs such as the custom SPIN frame, THM Clavicula one-bolt crankset, Nordischer Rahmenbau custom carbon stem, LEW custom Boron wheelset or extra light Schmolke TLO handlebar [the latter three being in general production]. Yet all of this does not stop GÃ¼nter to spend endless further hours in his workshop to shave off another tenth of a gram here or there - which after all does add up to quite a mass.
In the current setup the bike is down to a scant 3,195g.
For sure it has not been designed with powerhorses like Fabian Cancellera in the back of the mind, however it does not make any compromises regards safety, stability or riding quality either. The frame for example offers a lateral stiffness of 94Nm/Â° which translates to an STW of 138.75Nm/Â°/kg. Most of the other parts have been specifically designed for a rider of his weight in mind.
For everyday riding GÃ¼nter usually relies on Vittoria Crono Evo CS tires as the Tufo Elite 110 - whilst being "perfectly" usable - only holds up for a maximum of 1000km on the rear wheel which translates into just about a week of riding for GÃ¼nter.
