SHIMANO ULTEGRA HOLLOWTECH II Crankset 2x12-speed
ULTEGRA's new FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, ULTEGRA cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms.
An integral part of Shimano's new 12-speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the ULTEGRA crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements.

SHIMANO
In 1961, a 3-speed bicycle hub displayed at the New York Toy Show was the catalyst for what would eventually become Shimano North America Holding, Inc. The popularity of 20-inch wheeled bikes with hi-rise handle bars fueled a demand for multi-speed hubs and Shimano was producing an affordable and reliable version that caught the attention of the industry. So much so, that by 1965, Yoshizo Shimano, the youngest son of the company founder in Japan, opened an office in New York to get quicker product feedback and to provide technical and warranty assistance to retailers selling bikes equipped with Shimano parts. Though Shimano North America Holding, Inc. has grown from that first modest office staffed by only three people to a full distribution center with sales and marketing offices, the goals are the same: to ensure that Shimano always has a listening ear to provide feedback on relevant trends and needs of the North American market for both bicycle and fishing products and make those a reality for our customers. Additionally, a good product is often judged as such by the support that the company provides, and our offices are staffed with customer service personnel that can answer questions and facilitate warranty resolution with just a phone call. Shimano’s participation extends much further than the product, though. Through advocacy programs, ISO 14001 certification, and even commuter / car pool programs for employees, Shimano practices good local citizenship, pursues continued access to those areas that are enjoyed by outdoor enthusiasts, and is committed to minimizing our impact on the environment.Aucklander's Same Day Delivery
