Let's face it, the path to losing time is shorter than the path to gaining it. In fact, this unfortunate process reveals itself in innumerable ways in the saddle. However, in a time trial or triathlon, it most commonly occurs from a lack of access to your shift levers. For example, with mechanical groups, when you're taking the final corner, approaching 300 meters to the line, you're either stuck in gear or stuck in the extensions. Not the case with the Shimano Dura Ace Di2 ST 9071 11 Speed TT BrakeShift Levers. These 9071 brakeshift levers act as both the primary braking source and the secondary shifting source. In fact, the shift buttons themselves are actually Shimano's 9070 Satellite shifters. Still scratching your head Basically, these aren't meant for your extension bars. Instead, they mount to the ends of your bull horns, or outer bars, providing the ability to shift during hard exertions out of the corner, driving to the line, and climbing. If you're not familiar with Satellite shifters, you probably know them better as the 'top secret' sprinter shift buttons that Cavendish was subtly flaunting a couple of seasons back. But, unlike those, these levers opt for a more pronounced surface area, making shifting a thoughtless, fully intentional affair. Dwarfing all other advancements to the ST 9000, however, is the shifting itself this is where Shimano's 'Rider Tuned' philosophy really makes itself known. This is the title given to Shimano's campaign of providing you the best rider experience of your life. Throughout the group, every component has been given little custom touches, but the levers have received several. Addressing the 7970 complaint of dirt, grime, snow, or water getting into the small crevice between the lever and the hood, Shimano has narrowed this area, nearly eliminating the possibility of element corruption. Even more impressively, 9070 now enables you to select five different shifting speeds to the rear derailleur. And while this is...
