FINALLY ARRIVED!

So often at what passes for bicycle stores today, the young employees are disparaging of nice vintage French bicycles. Since their experience includes lowball Chinese mountain bikes as "normative", a cyclist riding a classic French bicycle just doesn't get the respect and service one might expect. (Anquetil notwithstanding. And Eddy rode a PX-10 as a neo-pro in 1967. But we digress)

Since we sold not only French bicycles ( Motobecane, Peugeot, Turin, Jeunet, LaPierre, Olympic Sport and many more) but also bikes from Belgium (Superia), Switzerland (Mondia, Allegro, Tigra, Mairag) and Spain (Zeus) with at least some metric dimensions, we're sympathetic.

Call us with your replacement parts requests.

But we do make an effort and can almost always find a functional solution if not the original part.

Standard BSC stems are too big to fit your classic French bike. We recently acquired some nice lathe tooling just for this problem. Now, we can modify some, but not all, handlebar stems to fit the smaller Metric size. $35 machining charge with a stem purchase. We can't cut _every_ stem but many models are suitable.
This 29.95 adjustable stem is $64.95 when machined to Metric dimensions

new service! now Nitto Technomic stems machined to metric size $75
Original French made classic aluminum stems as shown on right $59.95

For metric pedals, we recommend machining your cranks from 14mm to 9/16-inch. That's a difference of 0.0013 inches - we take out a small curl of aluminum about the thickness of a human hair. Service charge $8 the pair.

If you have a French crank, you might want to look at our selection of classic chainrings

In seatposts, we carry standard $20 seatposts (300 to 330mm in natural silver aluminum or black finish )

We began machining seat posts to 24.0mm for classic French 'Sport' bicycles about ten years ago. Many French makers built frames with a small-top seat tube. Such models include the Peugeot UO-8/ UO-18, Peugeot P6/P16, P8/P18 as well as Gitane Gran Sport, Motobécane Nomade, Nobly, Mirage, Peugeot VX40 and many others. Since we had sold truly thousands of this style bike ourselves, and, in America, a huge volume of nice classic bicycles remain in garages, we tried to do something about those short cheap steel seat posts out there. At first, we used 25.4mm ROC-Taiwan aluminum posts, which are readily available. We hired an American machine shop to turn them to the smaller French 24.0mm format

In recent years, with dramatic increases in both aluminum cost and delivery expense, seat post makers have changed to harder seamless aluminum material for post shafts. That change means thinner seat post shafts and, of course, lighter posts! Which is all fine as far as it goes. However, when we cut a smaller diameter from a modern post, we risk ending with a possibly unsafe piece. Some readers may recall the horrible seat post failure which nearly killed a Eurpean Pro from blood loss of a rent femural artery. There are better ways to die.

So, after two failures (fortunately, no rider injuries) we scrapped all the remaining posts and went looking for a manufacturer to make custom 24.0 posts for us. This turned out to be quite difficult.

Since we have some experience here, we recalculated how thin is 'too thin'. We set up a test fixture for seat post samples. Until early in 2009, no manufacturer has been able to deliver such a simple thing to our written specifications and within reasonable bounds of safety .

We're sympathetic to riders who have a too-short seat post on an otherwise nice bicycle. We pursued this new design diligently over nearly a year's time. The project came to a wonderful conclusion with a nice looking safe long modern seat post to fit classic French 24.0mm bicycles

For bottom brackets ( crank bearing assemblies) We have many original parts and a good selection of modern replacements both for French (m35x1) and for Swiss (the same but with a reversed right cup) frame threads. Phil Wood crank bearing cartridges and all threads of Phil stainless steel mounting rings in stock

For headsets (fork bearing assembly) we have NOS original French steel sets, $79.95, and a few premium quality auminum models. We do offer full machining services and we have full precision tooling in French formats.

If you have a damaged fork, we do fork alignments, we have some original vintage forks, we have some replacements in the original dimensions and if all else fails we can switch the front of your bicycle to a BSC fork, stem and headset. Don't despair!

In gear trains, we are one of the last places on earth with good support for Helicomatic systems and Atom-Maillard-Normandy hub service parts.
