Bikerumor Monday Mystery Pic

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

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

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

Agreed with the above–Mavic SSC bottom bracket, circa 1986.

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)

Let me know if anyone needs the champfering tool..

Damn you ant1, you got it before me.

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…

Are you sure it’s not a Park toilet paper holder?

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.

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.

The internets are wunderbar: http://www.velo-pages.com/main.php?g2_itemId=21262&g2_imageViewsIndex=1

Might be! Shoot me a email Gordo. treybiker at gmail dot com.

HAHAHA! I still have one of these in use on my vintage Yo Eddy! Mavic BB!

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?
