Parts for Old French Bikes From Harris Cyclery We love old French bicycles, but it can be hard to find parts for those built to older French standards and dimensions. We stock repair parts to help keep yours on the road. Bottom Brackets | Brakes | Chainrings | Cotters | Handlebars Headsets | Pedals | Rims | Tires & Tubes | Tools In addition to this commercial page, we have a very useful page of technical information and tips about older French bicycles.

For many, many years the T.A. Cyclotouriste was THE triple, and was standard eqiupmemt on virtually all top-of-the-line touring machines. They are unusually light, and have very narrow tread (a.k.a. "Q-factor"). Cyclotouriste triples work best for half-step plus granny setups, where the middle chainring is only a few teeth smaller than the large one.

They don't work with many newer "MTB-type" front derailers, due to tight clearance between the outer ring and the inside of the arm.

As it turns out, half-step-plus-granny setups work better with "double" type front derailers anyway.

The Cyclotouriste is unbeatable as a wide range double.

Only the chainrings are available. The crank set exploded view is for reference only.

CY205 Chainring-outer 40-52 teeth. 7075 aluminum.  

208 Chainring-middle/inner 26-42 teeth. 7075 aluminum.   

French-thread Bottom Brackets

Loose-Ball French Bottom Bracket Cup Set BBF37

They're back! Affordable, traditional bottom bracket cup set!

Cups, lock ring and retainer bearings, 35x1mm threads, Dual Right hand thread.

Fix that old Peugeot, Motobecane or Gitane on the cheap!

Many French bikes sold before the late 1970s used the now-obsolete French bottom-bracket threading: 35 mm x 1mm (1.378" x 25.4 TPI), right-hand thread on both sides.

Instead of the ISO standard threading: 1.370/1.375 x 24 TPI left-hand fixed cup, right hand adjustable cup. If your frame is made for a French-thread bottom bracket, a standard adjustable (right) cup will fit in, at least a little way but it will be very loose and will be unusable.

We were probably the last online source for loose-ball French bottom bracket parts, and the supply has just been replenished!.
