Bottom Bracket Overview - Bicycle Parts at discount prices / the Buyer's Guide / Bicycle Parts at their finest! / Professional Bicycle Source / Bike Pro There are only a few parts on a bicycle where bearing friction develops and the parts wear out. They are headsets, bottom brackets, pedal bearings, hubs, chains, and to a lesser degree rear derailleurs. Each time they wear presents an opportunity to upgrade. Bottom bracket spindles provide the cone races for bottom bracket bearings and are made in three ways; forging only, forging and polishing, and machining from billet. The forging and polishing type of spindle is, in color, either Black with Silver in the bearing surface areas or all Silver (possibly nickel or chrome plated). Billet machining is the process of taking a single piece of the metal and removing pieces of the metal (machining) until you are left with the shape you want. It is considered more desirable to have a large number of ball bearings in the bottom bracket. Ball bearings are found in bottom brackets in three ways; loose ball, ball inside retainer, and sealed cartridge. The length of spindle is the other criteria.

Classic Lightweights Hilary Stone The site for Classic and Vintage bicycles and their parts Delta Brakes In the late 1980s, at a time when Campagnolo was still hanging on to their woefully outdated derailleur designs and losing the technological battle to Shimano and Suntour, a new component line was introduced. Dubbed "C-Record," this gruppo was perhaps the pinnacle of Campagnolo's fanatical devotion to aesthetics. Perhaps the most unique component on the new C-Record gruppo (released in 1986) was the Delta brakeset, named for the shape of the housing covering the complex inner mechanism. Inside the housing was an articulated parallelogram mechanism that moved the brake shoes toward the rim by expanding outward and pushing one the upper portion of the brake arms. (Note: Although Delta brakes were first sold in 1986, they were originally shown to the public in 1984--for about an hour. The Delta brakeset (later offered in both the C-Record and Croce d'Aune gruppos) offered--in theory--the great stopping power offered by the mechanical advantage of the internal mechanism.
fixie a l' atelier des vélos VINTAGE ROSSIN ARCHIVE ITALIAN CYCLING JOURNAL: Columbus Steel, Tubing for Frame Building My latest project was a frame built with Columbus EL-OS (Over Size) steel tubing. Columbus steel tubing has long been the preferred steel tubeset for Italian framemakers. There have been quite a number of improvements and innovations through the years resulting in a large number of different tubesets. The framebuilder typically applies a Columbus frame decal to indicate the tubeset he used. On this page I will continue to add photographs of the various Coulmbus frame decals that have been used. First some history that appeared at one time on the Columbus website: 1919: "I want to do business in iron and steel and make a fair and honest profit" wrote Angelo Luigi Colombo, aged 27, to the lessee of what was shortly to become A.L.Colombo's small factory, the parent plant of the current Columbus. 1950: A.L. 1977: It was Antonio Colombo, Angelo's youngest son, who made a simple mark, Columbus, into the leading company for the production of tubes for top-of-the range frames.

Pricing If there is one notable feature to the vintage lightweight racing bicycle market it is the variability of prices. Prices also vary considerably even when buyers and sellers are well versed in the field. In the vintage lightweight market, there are many individuals willing and able to pay perhaps $350 - $750 for a bike. To the wealthy buyer, it is not a question of is it $2,000 or $3,000, but often is it the right color and size! Another important point to remember is that there are two ways to look at a bike. The above examples illustrate the need to look at the value of a bicycle as the greater of either it's "whole" value, or as a sum of its parts. Atala ...
