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.
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!
Installation was a breeze. Perfect fit and works great.
I have used the French B.B. units on other machines and this time it was a Maxi Sport track iron . Installation, as before , was a breeze and the chain line , perfect . We're happily back on the boards in the Forest City .
Restoring really cool Jeunet French Comet from the early 70's. Needed to replace the bottom bracket and my local shop suggested Velo Orange. Great quality and service. My new favorite bike parts supplier!!!
