Hi everyone,
Warning -- the following is boring and tedious. But I'm hoping you tech mavens will love this and share your wisdom to end my woes.
OK, Here's my problem: When I try to coast with the 2007 Mavic Ksyrium Elite wheels I recently bought via this site and am using with a newly built-up bike with a Campy drivetrain, the freehub locks up intermittently, causing the chain to go slack and dangle into the spokes. Basically, the bike wants to go fixie on me. When it happened while I was cruising in heavy traffic, it scared the bejesus out of me. ( I say "intermittently" locks up because when I take the freehub body off and re-lube everything, it will spin OK for a while, but then revert to madness after 5-10 minutes, usually while freewheeling down a hill.)
I've cleaned and installed Mavic freehub bodies plenty of times, and know all about the proper lubes, spacers, etc. And the bearings seem to be fine. So I'm really scratching my head here. It *seems* like a spacer issue.
So I'm wondering if it is this: The brand-new Campy-compatible Mavic freehub body I'm using came with the usual spacer that sits between the body and cassette spindle. But it also came with a "shoulder washer" and another little washer (pictured below).
I've never needed these doodads before. Apparently, these are to ensure compatibility with older wheels. But the verbiage on the Mavic tech site is vague to me.
"A shouldered washer is included in the free wheel kits to ensure the compatibility of these new free wheels with wheels marketed prior to 2013. It must be used instead of the flat spacer M40066 to install these new free wheels on the old wheels, whose axle (QRM hub) or axle end screw (QRM+ or QRMSL hubs) have a diameter of 8 mm."
If it stopped at the comma, it would be clear enough. But all the stuff after the comma just confuses me.
I guess my question is this: Do I need that dang shoulder washer? Or am I missing something really obvious here?
Any insights from my fellow TCCers would be greatly appreciated.
Thanks, y'all!
