There are various terrains and areas to cycle. While the majority of the population cycles in plains, there are steep areas too where cycling is not as easy. Gears are important for enhancing speed and reducing input efforts. The Shimano Ultegra crank set is made as a hollow outside chamber to optimize the balance between power and performance. Gear dimensions have been revamped to smooth the gear changing experience.
Hollow gear construction ensures rigidity and stability. This gear has extremely low weight with high performance. Contact BikesXpress to buy and learn more about the Shimano ultra crank set.
