Leading through Innovation: ENDURANCE LITE CONCEPT (ELC)
For a long time, STW (stiffness-to-weight) was deemed the absolute requirement for the development of new frames. We at BULLS know that this alone is not enough. Since 2010 we have been developing frames according to the ENDURANCE LITE CONCEPT (ELC). Comfort and ease are at the main focus here without losing sight of best conversion of pedaling force. Stiffness is indispensable in drive-relevant areas, but it has turned out to be hardly sensible to make the whole frame very stiff.
Too much stiffness in the wrong place leads to an insecure riding experience. The resulting lack of comfort also has an exhausting effect and thus negatively influence in the rider's stamina.
