(please see seatpost update box, below)
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.
Complete original French made metric headsets new in box
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.
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 $20 the pair and we stamp R+L on the inside of the arms, so you'll know they are no longer metric.
Metric Pedals Today 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 ) For classic Sport bikes, we even carry a special 320mm ( yes! 230mm of useful length!)
We'll ship TODAY!
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 so far as it goes. However, when we cut a smaller diameter from a modern post, we risk ending with a possibly unsafe thin piece.
So we searched 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 had 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
-due to the small diameter format, maximum recommended rider weight 195lb-

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. We also stock classic Simplex diagonal shift AV type front changers for those among you who have noticed that modern front changers are too darned thick and so cannot fit between ring and crank on classic bicycles.
