Shimano - Wikipedia. This article is about the Japanese sports gear manufacturer . For pages named . It produced golf supplies until 2. Headquartered in Sakai, Japan, the company has 3.
Shimano's primary manufacturing plants are in Kunshan, China; Malaysia; and Singapore. In 2. 00. 5, Shimano had net sales of US $1. Europe and 1. 7% in North America. Bicycle components represented 7. The company is publicly traded, with 1. Shimano Total Integration (STI) is Shimano's integrated shifter and brake lever combination for road bicycles. The Italian firm Campagnolo as well as US based SRAM are Shimano's primary competitors in the cycling marketplace. When the 1. 97. 0s United States bike boom exceeded the capacity of the European bicycle component manufacturers, Japanese manufacturers Sun. Tour and Shimano rapidly stepped in to fill the void. While both companies provided products for all price- ranges of the market, Sun. Tour also focused on refinement of existing systems and designs for higher end products, while Shimano initially paid more attention to rethinking the basic systems and bringing out innovations such as Positron shifting (a precursor to index shifting) and front freewheel systems at the low end of the market. In the 1. 98. 0s, with Shimano pushing technological innovation and lower prices, the more traditional European component manufacturers lost significant market presence. During this period, 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 and Sun. Tour (to a lesser extent) 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 upmarket if they established themselves in the lower market segments. In the 1. 98. 0–1. Shimano introduced three groupsets with . Shimano Ultegra And Dura-ace Di2 Electronic Shifting PriceShimano Ultegra And Dura-ace Di2 Electronic Shifting Manual![]() ![]() Features of these components include aerodynamic styling, centre- pull brakes, brake levers with concealed cables, and ergonomic pedals. By 1. 98. 5 Shimano introduced innovation only at the highest quality level (Dura- Ace for road bikes and XTR for mountain bikes), then trickled the technology down to lower product levels as it became proven and accepted. Innovations include index shifting (known as SIS, Shimano Index System introduced in 1. Also, these components could only work properly when used with other Shimano components, e. This viewpoint was based on the fact that Shimano became oriented towards integrating all of their components with each other, with the result being that if any Shimano components were to be used, then the entire bike would need to be built from matching Shimano components. The alternative perspective is that by controlling the mix of components on the bicycle, a manufacturer such as Shimano can control how well their own product functions. ![]() Shimano's primary competitors (Campagnolo and SRAM) also make proprietary designs that limit the opportunity to mix and match componentry. In 2. 00. 3 Shimano introduced . This development was controversial, as the use of Dual Control integrated shifting for hydraulic disc brakes required using Shimano hydraulic disc brakes, locking competitors out of the premium end of the market. However, with their 2. Shimano moved back to making separate braking and shifting components fully available in addition to the integrated . The DURA-ACE groupset is the result of Shimano’s ongoing passion for technology. This is reflected in every single component in the groupset.

The DURA-ACE series is SHIMANO's lightest, most ergonomic, and most precise groupset ever. As well as delivering the finest mechanical performance, it also serves as. The shoes have a recess in the bottom of the sole for fitting the smaller cleats and therefore it does not protrude, while conventional clipless road pedals are designed for road cycling shoes which have smooth soles with large protruding cleats, which are awkward for walking. The SPD range, in addition to other off- road refinements, were designed to be used with treaded soles that more closely resemble rugged hiking boots. SPD pedals and shoes soon established themselves as the market standard in this sector, although many other manufacturers have developed alternatives which are arguably less prone to being clogged by mud and/or easier to adjust. However, the SPD dominance in this sector has meant that alternative pedal manufacturers nearly always design their pedals to be usable with Shimano shoes, and likewise mountain bike shoe manufacturers make their shoes . SPD has spawned 2 types of road cleats which are incompatible with standard SPD pedals and some shoes – SPD- R and SPD- SL. SPD- R is a now defunct pedal standard. SPD- SL is basically a copy of the standard Look clipless pedal system. It has a wide, one- sided platform and a triangular cleat that is Look 3- bolt compatible. Shimano products. The product was introduced to the market in the fall of 2. ![]() It comprises four stepped planetary series offering a total of 1. Biopace chainrings are non- round, but unlike traditional oval chainrings which tend to have the largest effective gearing coincide with the downstroke, with Biopace the rings are oriented so the effectively reduced chainring diameter now coincides with the cranks being (at or near) horizontal, and the increased chainring diameter coincides with the pedals being close to TDC and BDC. The reasoning behind this is that it smooths the pedaling action, allowing the rider to carry a lot of momentum through the (downwards- based) power stroke, having it smoothly removed at the bottom of the stroke. This required an oversized hole in the crank 2. The theory behind this was to allow the foot to be lower than the pedal axle for better biomechanics. This system was relatively short lived, one reason being that the pedal bearings wore out quickly. However, they were used by Alexi Grewal (USA) in his gold medal winning ride in the 1. Olympic cycling road race in Los Angeles. But it did not catch on, as its arrangement of internally splined sprockets sliding onto the matching externally splined freehub was incompatible with the then standard separate hub and screw- on freewheel. When a larger number of rear sprockets came to be used, the freehub concept was re- introduced, and is now the dominant rear hub type. Freehub style hubs are inherently stronger than screw on sprocket and freewheel set ups because it allows the bearings on the drive side of the hub to sit nearer to the end of the hub axle, reducing bending in the axle caused by chain tension and rider weight, a significant problem leading to fatigue failure in many axles as 6 and 7 speed blocks were introduced. Previous to this hollow cranks tended to be tubes with a solid part welded to each end to take the pedals and the bottom bracket. For this system the bottom bracket axle was fused to the drive side crank and the non drive side crank fitted on a spline on the axle using pinch bolts. The bottom bracket bearings sat outside the BB shell in the frame, allowing the BB axle to be a larger diameter, making it stiffer and lighter. The bearing reliability of this system remains quite variable compared to previous Shimano cartridge BB's as Hollowtech II bearing alignment is at the mercy of the alignment of the BB shell threads and the facing of the BB shell rather than factory set by Shimano in the case of the cartridge BB's. Race face make a system with compatible bearings which they call X- Type. SPD clipless pedal PD- M5. This allows a certain amount of gear shifting under power, though this remains hard on the drivetrain. For a time 1. 0 mm pitch chains, sprockets, and chainrings, were used for motor- paced racing, to reduce the size and weight of the transmission system. Available in 3- , 7- and 8- speed with or without a coaster brake. The Nexus hubs are comparable in range to a full 1. This was introduced during the mid- 1. This was implemented initially by mounting the brake cable on a roller that moves towards the lever pivot in a slot in the lever blade as the lever is pulled. A second design pulled the brake cable downwards towards a cam near to the brake lever pivot instead. Servo wave has appeared for the first time on a hydraulic disk brake lever on the 2. Shimano XT groupset. The idea behind this was that the return spring in the actual brake could be designed to be weaker, thus giving an overall feeling of easier operation. SPD (. While not the first, its innovation was its small cleat which fitted into a recess in the sole of a shoe designed for SPD use. The recess allowed an SPD- equipped shoe to be used for relatively comfortable short walks, whereas previous systems tended to have a large, protruding cleat which prevented this. Clipless pedals use a system of cleat retention which resembles that of downhill skis, allowing for rapid shoe release, ergo clipless pedals are deemed safer than the older style(s) of pedal/shoe integration using toe- straps, et al. STI (. This made it possible to shift during uphill passages that require getting out of the saddle, and added general convenience for the rider. Although first generation of STI was unable to downshift multiple cogs which wasn't a problem in downtube shifters. Results. In the 1. Giro d'Italia, Andy Hampsten rode Shimano to its first Grand Tour victory. In 2. 00. 2, world championships in both the road and time trial disciplines were won on Shimano equipment. Alberto Contador's 2. Tour de France on a Shimano- equipped bicycle represents the first official General Classification victory in that race by a rider using Shimano components. It is an official approval stamp used to certify parts of Japanese vehicles – including bicycles. This mark signifies compliance with certain quality standards and is similar to the . Hollowtech II external bearing cups are also visible, between the crank arms and the bottom bracket shell. Discontinued after 1. STX- RC – Mountain bike groupset – Predecessor to Deore available during the mid- 1. STX – Mountain bike groupset – between STX- RC and Alivio groups. For a limited time mid- 1.
