French Threaded Bottom Bracket
Keep your old French bike on the road!
- Sealed, cartridge bearings for simplicity and longevity
- Classic square taper design
- JIS taper - works with most cranks
- Hollow, boron steel axle
- Aluminum cups
- 258g (110mm length)
- Spindles are available in a variety of lengths to fit most cranksets
- Includes crank bolts
Generally it is the crank model that determines spindle length, so check what spindle length the crank manufacturer recommends or measure your old BB. If between sizes, it's usually wise to choose the longer.
Use the Dajia Cycleworks Bottom Bracket Tool or Park Tool BBT-22 for installation.
I have used two of these with absolutely no problems, except that I found out that in 1968 Peugeot's workers were really in a hurry - bb shell was not faced. :-)
Thank you for keeping French threaded parts available!
Should have checked and paid attention to other reviews before I purchased. Thought I had a great solution but if I had read the reviews I would have known that the tapped threading on the Grand Jubilee was not deep enough to work with the velo orange 68mm. Also the original bb has offset shaft with a longer shaft on the sprocket side; that may not have been a deal killer. Not able to use and not able to return.

Just what I needed Thanks
Looks very good . Have not installed it yet .
I restored a 1970s Gitane Super Vitus road bike with one of these and it worked like a charm - until last week, when after approx. 2000 miles of trouble-free riding it started to unscrew on a major ride event, eventually shifting so far towards the drive side that the non-drive crank was rubbing quite hard on the frame and the big ring couldn't engage the chain.
I was able to get it fixed by the event mechanics, but I lost a lot of time and energy.
The precession forces are real. Definitely, definitely use additional threadlock compound!
