WTD: Mavic Zap parts!

Starfish is pretty straight forward.
Zeus a little less so. Cranks are Zeus Competition and I do not know the true BCD. They are defo not the same as Stronglight/TA 5 Bolt Cranks (50.4 BCD I think). But it is very similar.
Cheers

Here's the crankset

Ahh I have the Zeus criterium not the Competition. Will keep a look out!

Cheers! Feel like it's gonna be a tough search

Measure distance between adjacent bolts and then look here :- https://www.sheldonbrown.com/cribsheet-bcd.html

Yeah I tried that immediately, Sheldon's crib sheet doesn't go down low enough

BCD Is roughly 47

FWIW Zeus used a 119mm BCD for its more standard chainrings. I don't know whether they kept that for the large-small chainring interface bolts in chainsets like this one.

What's the distance between two adjacent bolts? It's easy enough to work out from geometry. Is that how you got the 47mm figure?

I think the distance was around 28mm.
I have also found online someone confirming that these cranks have a different bcd to the stronglight 5bolt cranksets. However someone mentioned it possibly being 55bcd. Who knows...

Here's a hideous sketch. Just divide the distance between two neighbouring bolts by sin(36°). If it's 28mm between bolts the BCD is 47.6mm.

Edit: Sounds like you already did this calculation as you said 47mm up the thread!

Bump!

I just got hold of a full Mavic SSC Groupset (!!!!!) apart from the simplex SLJ shifters, so I'd love a
pair of those.
I also got hold of a Starfish crankset but that is for a different build, I still need the 630 crankset to complete the aforementioned SSC groupset (would also be fine with a 170mm left crank arm as I have a 170mm right crank arm already).

Bump
Also need a bearing cover for the Mavic SSC pedals in the attached picture, does anyone have a broken Mavic SSC pedal that I could buy to take the bearing cover from?

Hey, I can't see a picture above, but are you after the flat quill pedals or the Look style clipless ones?

I've got a pair of the latter sat in my parts box which you're more than welcome to if they'll finish off the build. Like these, but in slightly worse condition (not my image).

PM me if you're interested.

Oh - I forgot to attach it haha
I'm after the flat quill style ones! But thanks a lot

No worries, good luck finding them!

Bump !

Hey man! Found this with BB included, did say I'd keep a look out! Hope this helps!

Ahhh just realised they are not the 2000's ones so maybe no good:(

Ah man I think they are correct but I don't need another set of the cranks, then I'd still have cranks left over!

Oh right, so you're just looking for the chainrings??

Yeah! I have a pair of the cranks already but no rings

Also looking for some Mavic 520 hubs if anyone has any?

bump :)
