Mavic Crossland freewheel

[6speedSchwinn]

Hi there

 

A little while ago the cassette on my Mavic Crossland rear wheel started pushing the chain forward when I was not peddling.  I opened the freewheel mechanism, cleaned it, oiled it and that solved it - for a while.

 

Since yesterday the problem is back with a vengeance.  I cannot stop peddling because the cassette just keeps on feeding the chain through.  I just went to the LBS and told them what is happening.  Apparently the free-wheel mechanism needs to be replaced (the 2 springs, the two little metal thingies and the casette body).  This is going to cost me R795 in spares alone!

 

Anybody else had trouble like this before?  Is it necessary to spend that much to sort it out?  Advice?  Anything?

 

I must add that I have done 9500km on these wheels and besides cleaning the freewheel mechanism once, I have never had them serviced.  They are as true as the day I bought them and I have done two Sani2cs on them.  I love these wheels and they have done me great service!

they are bullet proof wheels.

 

i had that problem on my CrossMax's and on my CrossLand wheels sets.

Those spring and metal thingys will not solve you problem by having them replaced.

 

What I found with mine was when the freebody if off, there is a whiteish yellow plastic ring at the open end which acts as a bushing. that wears down. This giving the free hub enough movement to cause a vibration. In doing this it pushes the chian towards the crankset.

 

3 ways of fixing it...

Pull appart after every 2/3 ride, regrease and put back together.

replace the free hub and dust cover

replace the wheel. They are only about R800 for a rear wheel.

 

there is a 4th way but that is a almost non existance chance.

having said that I was lucky to find the old school crossmax free body with a bearing on both side. never ever had a problem again. :-)

here is a more tech explanation... http://roguemechanic.typepad.com/roguemechanic/2006/05/how_does_a_mavi.html

 

you start experiencing some shifting issues that are not the easiest to diagnose.  These issues can range from noise to skipping, but usually both.  Well, what's up?!?! If you're lucky you or an astute mechanic realizes that the freehub body is exhibiting a significant amount of side play.  Again, you ask yourself,

"What's up?!?!"

"Why is this happening with my relatively "new" wheels?"

OK...here's the scoop.

http://roguemechanic.typepad.com/roguemechanic/images/img_0460.jpg Exhibit 1:  This is a photo of two Mavic freehub bodies.  The one on the left has been used for only one season of riding and a few races.  The one on the right is new.  It's hard to visually see any differences besides scratches, discoloration and the like, but where the difference is is in the thickness of the whitish nylon bushing...  The used freehub body is is really bad shape.  I know, that it's hard to tell without accurately measuring it, but the first indication of it's condition was the side play that it had with the cassette still installed on it.  The reason for this wear is the degradation or wearing down of the nylon.  This happens from normal riding but is accelerated by contaminants such as road grit, salt, and also by some types of greases or lubricants.  Mineral oil is the only lubricant that should be used.  The Mavic tech department uses Pedro's Road Rage which is essentially mineral oil.  All of this being said, the easiest way to determine if your Mavic freehub body is shot is to grab hold of the largest cog on your cassette and try to move it inboard and outboard.  There shouldn't be any noticeable play.  The more there is, the more it's worn

Service it with a oil/grease mixture. This will solve the problem. This is a problem found on all mavic wheels.

the Mavic Kysriums have the same problem and i fixed my friends set with a simple little bit of a clean and some squirt lube being wax based it helps to stay on (can also use the white lightning or any other wax based lube)

 

 

 

the sideways play i fixed with a Rubber O Ring made to size by an engineering works it was slightly thicker than the original nylon washer but it worked like a charm the wheels have not been serviced in a year and have not needed a lube since then

 

 

 

i got this tip from a very reliable source in one of the techies from cool heat who used to be the mavic dealers turtlek2008-10-07 07:09:46

Had the same problem with the Crosslands. Pain in the butt. The white/yellow plastic ring also wears causing the cassette to wobble. That is why I got rid of the Crosslands.

 

If you would prefer grease to mineral oil, try Castrol BNS grease. Much thinner. Use sparingly.

I tightened the nut that holds the casette body in place and the problem disappeared.  Now I have a new problem: this nut keeps on coming loose and I have to tighten it often.  What can I use to keep the nut in its place?
