Shimano has established a reputation for functionality, reliability, performance, and an ability to provide excellent value for money across a broad range of price points.
The brand's range-topping Dura-Ace series provides the ultimate in road bike performance, fit for the biggest races in the world, while its Ultegra and 105 groupsets cater for more budget-conscious racers and endurance riders.
At the entry-level end of the road bike market, Shimano's Tiagra groupset provides reliable performance and durability at an even lower cost, benefiting from technology and performance that trickles down from Dura-Ace.

Established in Sakai, Japan, by Shozaburo Shimano in 1921, Shimano has made bicycle components since its inception and released its first full groupset, Dura Ace 7100, in 1973.
In 1984, Shimano revolutionised bicycle gearing by introducing the Shimano Index System - the world's first indexed gearing system - and in 1988 Andy Hampsten (riding for the 7-Eleven team) took Shimano's first Grand Tour victory at the Giro d'Italia (having taken the race lead with his famous attack in the snow over the Gavia Pass).
Since then, Shimano has gone on to become the world's largest manufacturer of cycling components, with an estimated global market share of 70-80%, and a market leader in performance cycling components.
