Shimano road groupset hierarchy Claris – The Shimano Claris groupset is one of the lower-priced gearing options in the brand’s hierarchy. Sporting dual-control levers like the Tiagra above, Claris keeps things very simple with a triple or compact cassette set-up that focuses on low gear ratios to make hills relatively easy. Shimano currently still uses traditional gearing, which has seen great success over the years. Until X-Range, few riders had thought about changing their gearing. Only time will tell whether X-Range will overtake traditional gearing as the more popular gearing option. As the top-tier selection for bike riders, Dura-Ace is the premier option in the hierarchy of Shimano parts. Not only are they top-of-the-line in terms of price, but they also excel in performance where the other groupsets fall short. To Build Closer Relationships between People, Nature, and Bicycles. We believe in the power of cycling to create a better world as we move forward. We inspire all people to enjoy our products in their everyday lives and where they take them.
