  1. The picture is of a Mavic Sealed bottom braket
    these items were sooo amazing, so much it is still in use 27 years later

    still have the complete buke and gruppo

    it was and still is the ultimate quality

  2. as AAR mentioned … this is the Mavic BB which can be used even if the BB threads are damaged BSA1.36x24tpi … but it looks like the two nuts are put on wice versa as the BB needs to be champfered for the use with that BB

  3. Yes—Mavic bottom bracket–frames needed to chamfered—Mavic items from back in the day were great–still rockin’ a front road hub.

  4. It is a MAvic BB with cromo axle.

    I have the full Mavic ZAP grouppo, with Ti axle BB, cranks, brakes, and headset on a mid 90’s carbon LOOK.

    That BB still feels perfect today, almost 20 years later!

  5. I’ll jump on band wagon and agree with the 80’s Mavic BB
    To be more specific, I believe it to be a Mavic Floating 600 series BB (610-616 models)

  6. It’s a cartridge bottom-bracket for fitting to frames with damaged or missing threads – the threads on the cartridge itself are used to clamp the component into the bottom-bracket shell

  7. It’s the latest BB “standard” that we don’t know about yet…

    But we do know it’ll be 10% stiffer, 20% lighter, and 30% more expensive then whatever we’ve got working perfectly fine right now…

  8. I have a couple of those laying around and would kill to find the cutting tool. I still have my old Serotta T’Max frame with the chamfered BB shell.

  9. Mavic BB. In the late 90’s when I first started as a paid wrench, my shop still had few of these around. We would sell them as cheap frame fixes when threads were beyond repair.

  10. Got one of these in the parts drawers, with the lockring threads in pretty poor shape. Anybody want to sell me some lockrings, or buy the body/spindle assembly?

  11. I still remember getting my Mavic BB, I’d never had sealed bearings in any part of my bike before, the paper round just didn’t pay that well! It was still smooth years later. I also got the Mavic front and rear derailleurs and Wolber Aero 18 rims, I was pimped!
