The racing heritage of 105 is reflected in designs that have evolved directly from Shimano's experience in pro road racing. The 105 components are interchangeable with Dura-Ace and Ultegra due to identical 9-speed drive train specifications. The 105 group is available in the colours black and silver. By upgrading metal finishing, the group actualized its facelift of great value.
Features
The wide pivot link design boosts strength and rigidity. Flex is suppressed, creating sharp, precise shifts that are faster and smoother, even from low to high gears off of the saddle.Features
Ergonomic innovation is probably more critical to the higher standard of the new 10-speed S.T.I. levers than the added gearing. The narrower cradle-style perch welcomes the high-on-the-hood riding style and accommodates all sizes of hands. The shift internals borrow the robustness from our MTB technology which results in a smooth and effortless shift.Features
Specifications
You can hardly beat Shimano on the road. Continuing advances in human engineering technology stand behind road racing components that provide racing, sport and fitness cyclists with higher levels of control response. Each Shimano road racing group integrates a wide range of advanced functions that not only improve the cyclist's performance, but also make the bike a lot more fun to ride.Features
