October Three-piece[ edit ] In typical modern bikes, the bottom bracket spindle is separate from the cranks. This is known as a three-piece crankset. The cranks attach to the spindle via a common square taper, cotter or splined interface. Loose bearing[ edit ] Earlier three-piece cranks consist of a spindle incorporating bearing cones facing out , a fixed cup on the drive side, an adjustable cup on the non-drive side, and loose bearings.

Campagnolo vintage bicycle parts know for its outstanding products. Its quality, technology, innovation, luxury is unique in the bike world.
Larger Image The name says it all – the top of the Schwinn line. Schwinn today is part of Pacific Cycle. While Schwinn often had a reputation for building heavy bikes for kids, the Paramount line had a reputation for finely crafted, relatively light road bikes. That is obviously a great price. The very nice woman selling it was good natured about the low price.
The bike had belonged to her uncle who no longer used it. I believe the frame was built in The same site has the original price list. There is a larger photo in the Consumer Catalog. I like the and earlier catalogs where they took photos on location. The fashions are a hoot!
Seat posts for these frames are either This depended on the code of tubing used. My seat pin size is Tubing diameters are This tubing was introduced around
Late model Campagnolo Super Record crankset without the fluting on the crank arm. Many of the examples I have found have a date code of 21 inside a square, which translates to Starting in 85 it appears that Campagnolo took on a square with a two digit number inside.  = .
Some bike parts have a date code cast or stamped into the piece. This clearly is when the component was made and not when the bike was made, but unless the component or bike manufacturer had lots of stock lying around in inventory, the date should be a fairly good indication of the year of the bike. At least it would be the earliest date that the bike could have been made. Of course, all this assumes the bike has the original component. The most likely components to be original are the stem, handlebars, seatpost, and brakes.
On a vintage bike in excellent condition that apparently had a lonely existence in a garage all of the components likely are original. As the wear on a vintage bike increases, the greater the likelihood components are not original, either through replacement of worn parts or through component swaps. Swaps can take place early in the life of a bike as the proud new owner upgrades to new or used components of higher quality.
Swaps also can be made as the bike falls out of favor, or is being sold, where the higher quality components are traded for lower quality ones that the owner had onhand. Don’t all cyclists have boxes and boxes of old components in their garage? Most early Treks through about were sold as framesets. The components were added by the local bike shop or by the buyer.
New components often were used. Components also could be swapped from an existing ride to the new frameset.
The sliding hub, dual seatstay rod operated, back pedal derailleur cambio prototype is patented on May 4th and introduced in August.

Campagnolo’s Record hubs were the hub of choice in the professional peleton for 25 years and were sold in large numbers – almost all of us who were riding before about will at one time or another possessed a pair of these hubs.
The Tipo Roma model that became the Roma Olimpiade in has a pretty well defined lineage, however I have not learned exactly when Legnano first designated the Gran Premio model. The earliest Gran Premio that I have come across, that is also in my collection, is from There is some record to suggest that the Gran Premio model was introduced in , which may have taken place at the annual year end show. On the surface, the Roma and Gran Premio frames appear almost identical.
The head lugs, fork ends and stay ends are both chrome plated. The five bands on the seat tube were shared by both models as well as the decals excepting the round Gran Premio decal that was positioned on the down tube versus the Roma Olimpiade crest-shaped decal at the top of the seat tube. And both models were fitted with the beautiful brass figure of Alberto da Guissano pinned to the head tube.
One notable difference in the frame construction for these two models is the termination of the seat stays to the seat lug.
A bunch of guys sat down, decided on widths and diameters, and nothing ever changed… NOT! Keep in mind that the hub measurements refer to over locknut dimension—OLD—the distance between the outboard faces of the axles locknuts or endcaps. A mm road hub with a QR in a hollow axle If you are a road cyclist, things are significantly easier for you.
Date Symbols. – Record crank arms were not dated on their back side – The year of crank manufacture is the last digit in a diamond – The year of crank manufacture is the last digit in a circle Post “11” in a rectangle means , “22” means , and “33” means If yours does not have a number inside the diamond or circle you’ve.
The company history began more than one hundred years before then, in a time and in a Europe that would be wholly alien to those of us brought up over the recent generations. To be concise, the origin was some decades before then in when Josef Werndl b. He improved manufacturing techniques and diversified their offerings. They would continue the manufacturing but also develop the Werndl-rifle Model , a new modern breech loading rifle system.
Working with talented engineers including Ferdinand Mannlicher the company became the leading European producer of small arms. The company began producing bicycles in , and “Steyr” brand automobiles in The second member of the triad was founded by Gottlieb Daimler b. By March they successfully installed a gasoline engine and drivetrain into a coach thereby producing their first automobile, one year after Karl Benz. Established with DMG’s subscribed investment of , guilders, the company factory and offices were at Wiener-Neustadt and in Wein Vienna.
By establishing this subsidiary DMG became the first automotive multinational company. Eduard Bierenz, a friend of Gottlieb Daimler, was appointed to manage the company. Bierenz worked with co-founder Edward Fischer, owner of an iron foundry and engineering company in Austria.
Evaluation One of the axioms of the classic-bike business is that even very old bikes usually don’t show a lot of wear, because people just don’t ride them much. This bike never heard that axiom. It clearly has been ridden–a lot. The components, as I received it, were an eclectic mix of Shimano and Campagnolo parts, everything from a Shimano XT rear derailleur to a Shimano headset to a modern Campagnolo Chorus? Together, the components were virtually a bicycle history lesson from the late 70s almost to the present.
The components showed quite a bit of wear and were pretty grungy.

Opinions and value judgments are our own, unless otherwise noted — Sheldon d. Additions and corrections are most welcome. Sachs also made multi-speed internal-gear hubs in 3-, 5-, 7- and speed versions. Their “3 x 7” hub was a hybrid system, a 3-speed internal hub that took a 7-sprocket cassette, providing 21 speeds with only one chainwheel. Sachs formerly also made kick-back hubs and a “2 x 6” hybrid hub, the “Orbit”. The one clear area of domination for Sachs was its chains, which were generally acknowledged to be the finest available.
Sachs was the major European competitor to Shimano for the general bicycle parts market. Their parts in general were quite good, and stand up well in comparison with Shimano equivalents, although exchange rate problems sometimes make them less affordable.
Since I work alone, I have the luxury of maintaining a pretty messy work space, but writing this blog post plus the snowy conditions outside gave me some incentive to spiff my shop up a bit before taking these photos. In addition to being aware of French and Raleigh sizing issues, many vintage components require special tools.
My favorite sources for hard to find tools are: BikeSmith Design and Fabrication and J.
February 8th, the quick release hub is patented, the first of more than patents for Tullio Campagnolo. After fabricating parts in the backroom of his father’s hardware store (Corsa Padova , Vincenza), Tullio starts Campagnolo, S.r.l. with the production of the quick release hub.
Included at his site is Jalon’s excellent write up of the geometry and physical properties of the various tubings and what it all means. The length of some of the tubes in a set is different between makers as is the length of butted sections. As a result, the total tubeset weights are not indicative of the relative weight of the resulting bike.
They were a clever French innovation using a special cassette of cogs that mounts onto a special hub. Great idea, but poorly engineered and tested; they proved to be unreliable. For more information, see Sheldon Brown’s comments at http: What to do if you have one on your Trek and it no longer works, or you want a more reliable setup? If they are concerned about originality, they keep their original wheel and work to find a replacement for the hub or cassette.
They show up occasionally on Ebay. Imron is a two part paint that is difficult to use by other than professional painters. Imron is still available from DuPont. Some frame painters still use it today. However, some localities have clean air regulations that prohibit its use.
