So, there was me thinking getting my lovely new Mavic Cosmic Carbones wheels up and running would be a straightforward job, but I'm having problems with the spacing on the cassette.
The wheels didn't come with a spacer, but I have a spare plastic spacer that's about 2-3mm thick and looked to be the same size as the one the Mavic manual indicated as necessary (despite not supplying it). Without that spacer, when I tighten the locknut the cassette is still loose.
But...with the spacer the chain drops off over the top of the top sprocket as the gap between the spokes and the top sprocket is very big. Is changing the limit screw position the only way to fix this?
The gap between the cassette and spokes is so big it just doesn't look right. I'll be swapping out the wheels quite regularly (will use the Mavics for flats/TT routes and my other wheels for the hills) so really need it to be just a straightforward swap without having to readjust limit screws.
Have to say, first impression of the Mavic Cosmic Carbones is pretty disappointing. Fair enough, going with the aluminium-rimmed clinchers means you're not getting the full carbon effect but it's basically a normal wheel with a really flimsy piece of carbon stuck onto the inside of the rim. The big holes in the carbon around the spokes don't look very aero either. They do look well though so here's hoping they feel like they make some form of difference when I get them out onto the road.
