• Bicycle History. First introduced in 19th-century Europe, bicycles now number approximately one billion worldwide, providing the principal means of transportation in many regions, notably China and the Netherlands. BRIDGESTONE Bicycles. In 1970 Schwinn also changed the location of their frame serial numbers from the.

The first number following that letter is the last number of the year. If it's a 9, you have to figure out whether it's 1989 or 1999, bearing in mind all the while that Bstone quit exporting to the U.S. The other numbers identify the week and day it was made. Since your s/n is: A920328 A = January 9 = 1989 So your bike is a 1989 model year.

Bridgestone is an massive multinational business, one of the largest tire businesses in the planet.and a pretty small bike business, with its own manufacturer in Asia. In the late 1980s and early'90s, its U.S. Bicycle division was operate by Grant Petersen, a amazing, talented and idiosyncratic designer. Petersen, a hard-core bicyclist, marched to a 'various drummer' than most of the business. He released many enhancements to the market, and also strongly resisted other tendencies and innovations that hé didn't apprové of.

Bridgestones have got a backwards numbering system, and, usually, the lower the amount, the higher the quality. Road Models RB-1, RB-2, RB-3, RB-T. Bridgestone 'road' bikes, particularly the renowned RB-1, mix frame style taken from classic Italian street bikes of the '70't with fantastic Japanese craftsmanship and practical, reliable components.

The RB-1 was extremely popular with racers, and kept its very own against competing models costing 100s of dollars more. Raymarine st60 wind instrument calibration. The RB-2 got the exact same geometry as thé RB-1, but with slightly less costly tubing and considerably less expensive components.

The RB-3 had been a low-end model, of little curiosity. The RB-T had been a touring bike presented in the early '90s, a time when touring bikes were extremely out of fashion with producers. It was a extremely nice bike, but had trouble competing with the left-over share of mid-80s traveling bikes still in the pipeline. This bike also came with Avocet smooth tires, which are splendid wheels, but tough to sell, since many people believe (incorrectly) that they will supply poor traction. Mountain Bikes MB-1.MB-6.

Bridgestone has been one of the 1st businesses to jump on the mountain bicycle bandwagon in thé 1980s, but from a 'street' viewpoint. Early versions of the MB-1 came with drop handlebars and 126 mm dropout spacing! The main style of hill bikes in the early-mid '80s was the 'California cruiser' geometry influenced by thé Schwinn Excelsior 'kIunkers', with 44 inches wheel bases, 18 inch or longer chain stays, and frame angles in the high 60 degree range.

These bikes were quite steady for all downhill use on Repack hill, but were not quite good climbers. Petersen'beds Bridgestones acquired significantly steeper framework angles and very much shorter chain remains, which produced them substantially even more maneuverable and nimbIe than the older designs, and considerably much better climbers. In thé '80s this design was regarded 'major' but it proved itself on the trek, and had been replicated by everybody a several years later. This Bridgestone style still is definitely the regular for firm body MTBs. Some MBs were produced in Japan, others in Taiwan, various versions in different yrs. You can conveniently inform which, because the Japanese models all used lug design, while the Taiwanese models were Capital t.I.G.

In the earlier '90s, the Taiwanese MB-0 (a.t.a. 'MB-Zip') sent the package of lightness fór steel-framed hill bicycles. These top-of-the collection bikes had been amazingly light, but, sadly, a bit too light, and vulnerable to body failing if ridden hard off-road. The XO series. The 'XO' series were the many idiosyncratic of Petersen's i9000 styles. They were intended as fast, sporty metropolitan street machines, primarily for pavement use, but more durable than conventional 'road' bicycles. Most of them presented ' ' handle bars and slick medium-width auto tires.

The top-óf-the-line X0-1 and other upper-end models utilized 559 mm (26 inches) tires, and 23.8 mm (15/16') handle bars that used 'road' type brake pedal levers and bár-end shifters. Thése bicycles, specifically the XO-1, are usually extremely sought-after 'cult' bicycles today.

The XO-5 had been even more like a normal 'hybrid' with 622 mm (700c) wheels and a variant moustache handIebar with 22.2 mm (7/8') size, that utilized 'hill bike' kind handles. This design was instead too jeopardized.

That edition of the moustache handlebar had fairly bad ergonomics with the supplied handles. The CB-1.CB-3.

There has been constant pressure between Bridgestone Us and the mother or father corporation in Asia. While the employers noticed that Petersen has been a extremely talented designer, he was probably a little bit too individualistic and eccentric for the corporate and business lifestyle. There were energies in Japan that needed to create a even more mainstream bicycle, like everybody eIse. In the give and take between the sections, some models went one way, others the various other way. The CB-series (Town Bicycle) was intended as a bicycle for the nón-enthusiast. There had been nothing incorrect with them, but nothing special, possibly. These had been all Taiwanese models.

The almost all interesting of them had been the CB-0. After Bridgestone Japan taken the put on Bridgestone USA in 1994, Grant Petersen went on to found. As professional of his very own domains, he has since long been free to mar to his very own drummer, producing Rivendell, Romulus, Saluki and some other bicycles with his specific design taste. The Rambouillet and Romulus are similar of thé RB-1, or what the RB-1 might possess long been if Petersen had been given a free of charge hands, and if 57 mm reach brake pedal calipers had been accessible in the early '90s.

The Atlantis may become observed as the Iineal descendant of thé XO-1.
