sram的产品介绍（SRAM product introduction）[turn] actually SHIMANO\FOX is rubbish today saw a teaching post, learn a lot, posted we learn together.Why use SRAM products?SRAM, the United States bike accessories brand, is now a SHIMANO class bicycle package development, design and production company. After years of development, in the global market, SRAM has been leading the SHIMANO, see the UCI rankings, the top 6 in the world cross country mountain occupation are used SRAM driver products, another 09 years of the tour de France champion, the team also used the SRAM highway suite. SRAM's rays cover SHIMANO from two aspects of mountain and highway. So, the history of SHIMANO kingly way has passed, and SHIMANO is not the only choice for riders.I don't want to copy the contents of the manual and the official website, because I am also using SRAM products users, then I combine my actual use, chat about SRAM products.SRAM many riders think that only the speed, but it is not, the SRAM suite of more than SHIMANO fork, less wheel group (road carbon knife) SRAM bought several famous bicycle accessories brands, including SRAM (speed, flywheel) ROCK SHOX (fork) AVID (brake (TRUVITUV) the tooth disc group).A. The first is the speed change at SRAMThe biggest difference between the SRAM shift and the SHIMANo in design is the pull ratio. Pull is dip movement and shiftingstroke ratio. The use of the SHIMANO is 1:1.25, which means a 1 distance, the displacement is 1.25. dial and SRAM using a 1:1 cable, which means the 1 struck, the pull wire is 1.SHIMANO than the displacement dial has the advantages of soft feel, stop motion stroke is small, the ratio of amplification after dip cable transmission to dial, so soft and smooth transmission. SRAM and 1:1 design, the pull force of the finger wholly intact after the transfer to the dial dial, so after the better fault tolerance ability (SRAM line loose qwaqwa can accurately at the same time, because the dip forming speed) lengthened, feel tough altogether, after shifting spring strength because of much larger than the SHIMANO, after shifting greater strength. Fast fierce speed. It can be seen from the riders on the choice of riding strength large, most riders choose is SRAM speed, because of the characteristics of SRAM in the fierce off-road riding more feel more reliable and provide speed dial to reflect.Two. SRAM's ROCK SHOX front fork.The front fork of a mountain bike was invented by ROCK SHOX. And ROCK SHOX has been the ruler of the XC competition throne. Watch the top international events, SID's appearance rate is much higher than FOX, and the results of the line of drivers, almost all using ROCK SHOX products. FOX is a myth in the country and is regarded as a god. In contrast, FOX, and now do not have the ability to get the highest honor rainbow strip, but instead of being friends curse R7, there are rainbow bar, SID is rainbow bar has not been canceled. As God's word, the rainbow strip is still necessary (the rainbow bar is a sign of the UCI champion, and if the product has not won a world class title, it is noteligible to use the champion rainbow bar). The front fork of ROCK SHOX has a very attractive technique, that is, positive and negative air chambers. By adjusting the pressure of two positive and negative air chambers, the front fork has a variety of shock resistant linear. Small vibration is very sensitive SID and REBA increased negative room, can reflect a higher sensitivity than FOX small vibration. The FOX design is very tricky, soft stroke, eat fast, this feeling can make people feel very comfortable, so that FOX is very good. But in fact, let's see what XC rides are about, light, fast, and flexible. Well, FOX's size, shock taking, and more collaborative design aren't perfect. Think of FOX than the SID run, because the design of FOX open circuit, open circuit run, but the oil sealing ability is poor, so the feeling of FOX inner tube is always wet oil, fork and open oil when the muddy off-road conditions, great influence. The 10 FOX has also become closed oil circuit,This is consistent with the SID has been using the oil circuit design, we are reflected in the FOX is not run. In fact, whether it is FOX or SID, REBA are very run, but need to run in a relatively long period, because some riders off-road riding less, probably the front fork did not run well for half a year, it said SID, REBA do not run. As for SID, REBA linear is not as good as FOX, I think that different people have different views, because the head of the FOX and the terminal segments linear, stroke eat quickly, has the advantages of high comfort, the disadvantage is poor when the whereabouts of the front suddenly becomes very low, people feel that the front fork support soft, easy to somersault. SID REBA Duan Duan soft, end hard features, in fact, also meet the requirements of off-road riding, when the strength of the hard side, providing a solidfeel, while the front fork is not easy to render. In addition, compared to the front fork work, FOX stickers too perfunctory, and in contrast, ROCK SHOX to be more careful, with different colors of stickers, you can perfectly match the frame.Three. AVID brakesAVID brakes, I can say, dominate the cross-country ride, and the North American market, where the market is most competitive, illustrates the strength of the people. This year's new series can be said to be the most cost-effective brake. Tough feel, tough power, tough feel, clear linearity, flat price, AVID failure is difficult, AVID all series of brakes on the hot on the problem. Even the GIANT brake such SHIMANO death SHIMANO kit with AVID, so that their high-end vehicle sold. Some people say that the AVID linear difference, trouble check under braking mode not is not correct, with several fingers grabbed the brakes, AVID power of nature will sudden death. AVID brake contact clear, powerful, a finger can be stable and clear control of braking efforts. The single finger brake can hold the handle firmly in the cross-country, and control the brake force accurately. AVID and the brake model number, variety complete, whether it is the pursuit of lightweight brake force or the pursuit of stability, there is always a brake for AVID, and the relative price of other first-line brand price of AVID brake, and too much. Now most popular R and CR models, XC DH to all, no matter what kind of riding style, are suitable, lest because days after the technology upgrading and upgrading has become a drag on the vehicle brake.Four. TRUVITUV's set of teeth platesTRUVITUV is a tragedy at home, because the brand is big, but also has low-end products, TRUVITUV has become the first target of counterfeiters... Everyone has been blacked out by the fake TRUVITUV products. In fact, the TV group seat tube design is very conservative, seemingly insipid appearance, the results have a stable quality, solid strength, a long service life. As for TV's disc, it had a hard disk before, but that axis was a ticking bomb, and it was easy to rot. Finally, the 10 section solved the axis problem perfectly. After I used it myself, I could not hear the annoying "KaKa" sound. The exterior has also maintained an American simplicity and rugged style. And SRAM other products, can form a appearance of high integrity, product performance harmony of the car.SRAM's products, like SHIMANO, have been improving. It turned out that a few years ago, the product situation, do not get it, now to mention, the original use of SRAM fewer people, fewer people will tune. Today, the correct SRAM speed adjustment, there is no speed change, noise, tooth sense and so on. SRAM's growth and expansion, so that we have a choice, for riders is a blessing。
