Shimano Bike Parts

For over 90 years Shimano has been making quality bicycle components. It started back in 1921 when Shozaburo Shimano manufactured their first bicycle free wheel. Of all bicycle components, free wheels entailed the highest level of technology to produce. It is this kind of ambition that put Shimano at the top of their game. Since then Shimano has maintained this high level of ingenuity to produce some of the best bicycle components in the world. Whether you’re a mountain biker, road biker, or just use your bike for getting from point A to point B, Shimano makes a component to fit your needs.

In 1973 Shimano revolutionized the cycling world when they released their Dura-Ace series of road racing components. Dura-Ace represents the pinnacle of cycling performance and engineering. To wear the Dura-Ace badge, each component must be race proven at the elite level in the world’s most demanding races. When you get Dura-Ace, you know you’re getting the highest quality and best performing components Shimano has to offer.

Now that Shimano had cemented their dominance with their Dura-Ace line of components, the next challenge was to develop groupsets that would appeal to the average joe that maybe didn’t have a fortune to spend on bicycle components. Thus, in 1982 the Shimano 105 road group hit the market. 105 was the everyman’s group that even though it came in at lower price point, 105 didn’t skimp on performance. It was at this same time that Shimano dropped their XT line of mountain bike components on the world. Since then XT has become to be known as Shimano’s workhorse groupset due to its versatility, durability, and proven performance.

No matter what type of rider you are, Shimano makes a component or groupset that will suit your needs. If you’re the type of rider who does frequent races and demands the best components money can buy, then XTR or Dura-Ace is for you. If you’re a rider on a budget, and in search for the best bang for your buck then something like SLX or 105 may be just what your looking for. For the rider that likes to tackle technical rock gardens, steep chutes, and X-Games style jumps, Shimano makes Saint and Zee just for you.
