Shimano is the world's giant mountain bike with a history of nearly a hundred years now. Born in 1921 in the city of Sakai, Japan, the founder Shozaburo Shimano began producing free wheels for bicycles, which were exported all over the world. After the crisis of the '30s and World War II, during very difficult for Japan, Shimano tried his hand at building it's first change in the mid 50s, with the first exchange in 1956 and derailleur with a internal gear hub 3-speed in 1957. Born in 1965 in New York and the Shimano American Corporation, in the same year, Shimano arrives in Europe at the Milan Fair cycle: the beginning is imported into Europe. In 1970 the division where fishing is among the industry leaders.
Another major innovation introduced by Shimano in the derailleur is the Shimano Total Integration in 1989 for mountain-biking, indexed with a command with two levers to change the report. The following year, the novelty is also applied to racing bikes, with the revolutionary change in the gearshift, which pass from hand lever on the downtube to be integrated into the brake lever. Despite the many proposed changes, which in the short span of 15 years, enable the leap from a product which hopes to enter the market until an innovative top of the range, the first major successes in Shimano-equipped bikes for professionals arrive late. Only in 1988 with the Tour of Italy Hampsted reach success in a great ride and you will have to wait for their first win of Armstrong in 1999 to see a Dura Ace to be taken to Paris by the yellow jersey. In 2002 all three grand tours protagonist Dura Ace.
Now in recent years is occurring invertimento course with all the great champions who use Shimano, both on road and MTB, although the giant SRAM is growing visibly.
New system for Shimano XTR
Let's start by saying that the new 2012 XTR vision has improved a lot and doesn't go unnoticed as aesthetics, especially for his crankset very aggressive in line with competitors. The weight is low (always higher than the competitor, however, XX with +191gr), well-made brakes and the gearbox which has a new gem (see photo above) with a locking rear derailleur that allows you to rein in the cage of the exchange so as not to blast the chain. Excellent for many who perhaps found the end of a descent into a XC race were with the chain down and entered into a panic situation. The exchange rate with this system becomes slightly harder and less precise, but you don't see big difference in average biker. The brakes are fantastic, require very little maintenance and are rated very high considering their weight. The crank should give it a little criticism, ie the choice of chainrings sizes: 40/28 - 42/30 - 44/30. Ok that is a change for the agonist, however, the toothing more affordable could think of, even in the optic 29er. The XTR is still a change for athletes who want real performance and light weight.
