Hi,
This tool has come with a road bike running new dura-ace (7900) road bike with mavic wheels. It is flat steel with a rubber grip in the middle.

The three of us could not work out what it does, neither the bike rep or shimano.

So what does it do?

I know its a MTB forum but you seem all seem fairly knowledgeable.


Cheers
Hugh

Does it have the R-sys mavic wheels? if so that's the tool to pry up the ring inside the hub shell that locks the carbon spokes in place. A job you have to do BEFORE you can true the wheels. If you don't remove the ring first, the spokes will twist as you tension the nipples and then well... expect the spokes to break when you go and ride the wheels after.

The wheels are Ksyrium Elite but will have a look on the techdocs website see if its listed there.

Thanks
