can you only use mavic lockrings on mavic hubs or will a dura-ace or soma fit fine as well?
and while I have your attention are EAI cogs and or Phil cogs thicker than say a cycle pro or surly cog?

Mavic 33.0x1 mavic only

werd but the wheels are so nice who cares about the extra proprietary parts

it's also 42mm chainline.

You could use a paul crankset in that case.

You got the lockring thing right. And they dont usually come with the wheels, its an extra order!?

no you are thinkin 44mm chainline on the paul comp stuffs

it came with a lock ring.
but I cant get the thing to butt up against the cog. the cog would spin back if I tried to skid or skip.
I put a 2mm spacer behind the cog and it seems to work but it seem that I might strip the threads if I try to tighten it all the way. I could still crank on the lockring but I'm scared. and I was wondering if A better Cog might be thicker?
has anyone had this issue?

I use a 16t DA cog with the Mavic lockring on my Ellipses with no problems. I have the cog oriented so that the flanged side of the cog faces inward towards the hub. I can't recall off-hand what the chainline ends up being, but it's more than 42mm.

The Mavic website specifies a 33x1.0 french-threaded lockring (Mavic Part no. 32397101). Harris Cyclery sells them for $13.

Some of the cheap cogs are more narrow than DA, which could lead to the problem you describe, also the case if you ride miche hubs.

get a better quality cog phil wood eai

F@@K the spacer was a bad idea just stripped off my lockring (threads off the hub).
trying to stop at a red light.
kinda scary.
glad I wasn't bombing a huge hill.

They're 44mm chainline.

oops

no i think if you put a 2mm spacer behind the cog the chainline is 46mm

yea I figured that out after the post. A little sick and stupid.
thanks.

french standard

back in the day there were a ton of standards, swiss, french, english, italian, etc.

I put a soma lockring w/ eai cog on my mavic ellipses, no problems except the lockring thickness was greater than the one that came stock w/ the rush hour pro, it also had a washer. So, I didn't use a washer. Seems to work fine.

you must have forced the threads a bit to make it fit.
and that would be fine with me if I knew the lockring threads wouldn't strip right off under a hard skid like it did with the spacer. two day of riding them an they are already a little f##ked.

BUMMER!

well, they'll still make OK dedicated track wheels.

If I take off the already tight soma lockring, that seems to be working fine, and replace it with the proper mavic lockring, will it fit right...or did I screw up the threads by tightening the soma onto the cog? Maybe I should just leave it be until I wear out the cog?

if it works don't f**k with it.
you won't be able to put a mavic ring on that side. but you have two fixed side so your good.
