With the introduction of speed drivetrains, many owners of older ROL wheelsets are wondering if they are speed compatible. This depends on the drivetrain you are using, as well as the purchase date of your wheels. For Campagnolo drivetrains, our freehub bodies are directly speed compatible. Wheelsets purchased prior to December are NOT speed compatible, and will only work for 9 and speed cassettes. Wheelsets purchased after December are speed compatible, and indicate this on the freehub body. If you are unsure when you purchased your wheels, please contact info rolwheels. Yes, all of our wheels are hand-built in the United States in our Denver, Colorado facility.
A Reappraisal of Tullio Campagnolo
While it is true that the RD does have a protective anodized surface finish on both its hub body and axle unlike its predecessor, perhaps more importantly with respect to its being able to better withstand the rigors of racing, it also has an outboard bearing on the freewheel side of its rear hub absent the end cap found on the corresponding model RD. By virtue of placing the drive side bearing such, this version of the MAVIC rear sealed bearing hub allows for a wider distance between load bearing points with particular emphasis on the amount of outboard axle overhang on the freewheel side, thereby minimizing the opportunity for bending said axle under extreme duress such as when a powerful rider is sprinting or climbing hard out of the saddle.
This feature was later incorporated into both the and freewheel threading road hubs which succeeded the RD and RD models in

Campagnolo is an Italian manufacturer of bicycle components with headquarters in Vicenza , Italy. The components are organised as groupsets gruppi , and are a near-complete collection of a bicycle’s mechanical parts. Campagnolo’s flagship components are the Super Record, Record, and Chorus groupsets with all three representing their recent shift to speed drivetrains. Founded by Tullio Campagnolo , the company began in in a Vicenza workshop.
The founder was a racing cyclist in Italy in the s who conceived several ideas while racing, such as the quick release mechanism for bicycle wheels, derailleurs , and the rod gear for gear changing. Campagnolo has been awarded more than patents for innovations in cycling technology. At the end of the s, Campagnolo started to manufacture magnesium parts such as wheels for sports cars like Alfa Romeo , Ferrari , Lamborghini , and Maserati , and built chassis for NASA satellites in In the s they also supplied wheels for Ferrari’s Formula One cars.
Campagnolo worked with the manufacturer Colnago and racer Eddy Merckx and produced lightweight parts for the bike he used to beat the world hour record in An unsuccessful foray into mountain biking , the overbuilt and heavy Euclid, Centaur and Olympus groupsets contributed to the company’s decline during those years. By the time the expensive Record O. As a result, Campagnolo pulled out of the Mountain Bike market in

I know that they’re Record hubs but I could use some help in identifying the vintage, as I assume that maintenance procedures and replacement parts will vary. Last edited by rwsaunders; at AM. They are very desirable mostly because they are silver. Good bearings spin nice, large axles, easy to maintain.
The original patent for the quick release, said to date from , does Simplex or Huret, hubs from FB, cranks from Stronglight or Gnutti, etc.

It had completely different lugs and a drastically changed tubing. This one is a 2nd gen Master dating from about with internal rear brake cable routing.
It is thought that it isex Team Wordperfect bike… It is fitted with a Suntour Superbe Pro groupset… The bike is is in very good not heavily used condition but has quite a number of marks to the paint. We built it up for a customer two years ago; he had it repainted at Argos in a classic blue red combination and we built it up with a mix of old and new parts — Stronglight 49D chainset, Suntour Cyclone GT gears, GB bars and stem, Brooks saddle, MKS quill pedals, Shimano cantilever brakes and wheels with Campag large flange Tipo hubs on Mavic MA2 clincher rims.
He did not use it a lot and has now part-exchanged it back for us to build another frame up for him. It has a real charm and the Super Champion gear gives it a very distinctive look. This Super Corsa frame dates from about —9 — the head lugs have the forward projections on the side that were removed from the head lug design around — This bike is an older restoration which I think uses all the original parts — it has Campagnolo Gran Sport rear gear and large flange Gran Sport hubs of the correct period, steel seatpost, Ideale 80 saddle, Cinelli steel bars and stem, no-name steel chainset with Simplex double rings and Universal Extra brakes.

The Campagnolo Gran Sport rear derailleur lost its cable housing adjuster screw around The word “RECORD” was added to Campagnolo hub barrels.
We did some real research, and we were surprised by what we uncovered. Cyclists who know their history have heard how in , Campagnolo raced in the Gran Premio della Vittoria , got stuck in the snow when he could not open the wingnuts on his rear wheel, and lost the race. He then invented the quick release, which became the foundation of the company that bears his name. That is the legend, but what is the real story of Campagnolo? Based on research in European archives, patent searches and contemporary accounts, the conclusions were published in a page article in the Summer Bicycle Quarterly.
Campagnolo was less of an inventor of ground-breaking innovations, and more of a visionary who foresaw trends and even shaped them. He showed great ingenuity in improving those ideas to give racers exactly what they wanted. Back to the quick release: It appears that Campagnolo did not invent it at all. The story of the race in the snow is a myth. The original patent for the quick release, said to date from , does not exist. Later patents by Campagnolo are written very narrowly for improvements or special features of the quick release, indicating that he could not patent the cam-actuated quick release itself.
Campagnolo got this idea from a French cyclotouring derailleur, the Nivex left. He was not the first to adapt the parallelogram derailleur for racing bikes, either: That honor goes to the JIC derailleur middle.

Date: 7/8/ I recently purchased some bearings for my year campagnolo Record hubs from you. I’ve been nothing but impressed with your selection.
Many thousands are still offering excellent service to their owners. So what is it that made the Record hub so special? The quality of the cones and bearing cups was a distinct cut above anything else made in and continued right up to the end of production to be the equal of any other hub. You could simply feel that the bearings were better than any of the competition… The axles were also made from high quality steel alloy that rarely bent or broke except under extreme provocation and the hubs were well sealed with removeable tight fitting dustcaps against the ingress of dirt or water.
And finally they were fitted with the best quick-release available at the time by quite a long way. On November 4th, during the Gran Premio della Vittoria race across the Croce d’Aune Pass he could not loosen the wingnuts of his wheel to flip it over to a different sprocket due to his frozen hands.
Effective date : Wheel hub having a central tubular portion and a pair of side caps, whose diameter is larger than the said central portion is provided. The hub comprises a monolith body made of fiber-reinforced plastic material. This invention relates to a wheel hub for a bicycle, specifically a competition bicycle.
The main objective of the competition bicycle manufacturers is to reduce the weight of the single components as much as possible. In the case of wheel hubs, conventional technology involves the use of metallic light alloys, such as aluminium alloys and similar.

It was part of a series designed to interest science students in engineering and had such an utterly dull title that I simply had to attend. We pampered scientists were supposed to marvel at the fact that there could be so much sophistication captured in such a humble engineered object. The lecturer ended his for, strangely, the lecturer was a man diatribe by stating that, of course, we would never come across a bolt which had all twelve of these features, but at least we would appreciate those few features that real-world bolts did actually possess.
A few weeks later I was fitting a Campagnolo Nuovo Record chainset, and happened to look at the crank bolt. This simple component was an engineering masterpiece – in defiance of the lecturer, every single one of the twelve features that he had mentioned in his tedious lecture was present and correct. To cap it all the bolt was beautifully finished even though it would be hidden by a dustcap and was made of some kind of steel that appeared to have near-infinite tensile strength.
