Okay we all know that the Mavic SSC stuff (both the 801, 851 series with the retrofriction shifters and the 8 speed 821 indexing shifter series - 840, 841, 845) were completely disassemblyable, and that back in the day you could order any part.

This would have been cool because you could order a medium cage to convert your derailleur from the 840 to the 841. Or a different front derailleur body to cover you Mavic build for both braze on and clamp frames.

So I look every once in awhile for Mavic parts and bits.

Sometimes I come across stuff I just don't know what it is.

This is on eBay now:

Its listed as Mavic Part 357015

What the heck this?

[edit - straight from France, the seller says that Mavic Part 357015 are supports for the Mavic Aero bar. Now we know.]
