Shimano

Current mountain bicycle groupsets include:. This has been considered to be a disadvantage by serious weight trainers who have stated that it reduces the efficiency of the exercise provided. Current road bicycle groupsets include:. Soloflex machines use an elastic element to provide resistance which means that force increases further into the exercise. In fact, VIA is an official approval stamp used to certify parts of Japanese vehicles - including bicycles. The case was settled out of court with an 8 million dollar cash payment to Soloflex [2]. Many people believe that "VIA", which is stamped on all Shimano parts, is a form of corporate logo, since it does not appear on Campagnolo parts, for instance. Soloflex, the company has been involved in a major lawsuit over the similarly named Bowflex exercise machine which they have claimed damaged their marketing both through "copycat" advertising and later through a major product recall[1].

Shimano also introduced new proprietary standards for disc brakes and hubs, and for bottom brackets and cranksets, further fueling speculation about monopolistic intentions. Soloflex also makes the Rockit and adjustable dumbbells. This development was controversial: critics viewed it as an attempt to monopolise the mountain bike components market because the use of Dual Control integrated shifting requires the use of Shimano brakes, and the Rapid Rise derailler is believed to work more effectively with the Dual Control system. The machine was the first of its kind. In 2003 Shimano introduced "Dual Control" to mountain bikes, where the gear shift mechanism is integrated into the brake levers, and reintroduced the "Rapid Rise" rear derailler which works in the opposite direction to traditional deraillers. Soloflex refers to an exercise machine and the company created in 1978 by Jerry Wilson which makes the machine. World championships in both the road and time trial disciplines were won on Shimano equipment.

In 2002, Dura-Ace equipped bikes were ridden to victory in the Tour de France (Lance Armstrong), Giro d'Italia (Paolo Savoldelli), and Vuelta a España (Aitor González), marking the first time Shimano componentry had been used to win all three grand tours. Lance Armstrong's 1999 victory in the Tour de France on a Shimano Dura-Ace equipped Trek was the first time Shimano components had been used to win the grand tour. In contrast to the near-universal marketing technique of introducing innovations on the expensive side of the marketplace and relying on consumer demand to emulate early adopters along with economy of scale to bring them into the mass market, Shimano introduced new technologies at the lowest end of the bicycle market, using lower cost and often heavier and less durable materials and techniques, only moving them further upscale if they established themselves in the lower market segments. SunTour eventually lost the commercial battle.

While both companies provided products for all price-ranges of the market, SunTour also focused on refinement of existing systems and designs for higher end products, while Shimano paid more attention to rethinking the basic systems and bringing out innovations such as index shifting and front freewheel systems. When the 1970s United States bike boom exceeded the capacity of the American and European bicycle component manufacturers, Japanese manufacturers SunTour and Shimano rapidly stepped in to fill the void. SRAM is a competitor as the other major manufacturer of mountain bike groupsets, though they are now introducing a road groupset as well. The Italian firm Campagnolo is a competitor as the other major manufacturer of road groupsets.

Groupsets commonly include: crankset comprising cranks and chainrings; bottom bracket; chain; rear gear cogs or cassette; front and rear wheel hubs; gear shift levers; brakes; brake levers; cables; front and rear gear mechanisms or derailleurs. These components are generally organised and sold as groupsets intended to be supplied as a near complete collection of a bicycle's mechanical parts. Shimano products include drivetrain, brake, wheel and pedal components for leisure, road and mountain bikes. .
