Grit or gravel in my mavic cosmic carbones

Hi folks,

Having just got a nice new pair of cosmic carbones for crimbo, i have noticed a bit of a rattle when i spin them at slow speed. The trouble seems to be small bits inside the carbon faring. No idea how they got there and not quite sure how to get them out?

Idea so far is making an small tube to connect to a small vacuum cleaner i use for machines at work to try to suck it out from the innertube valve hole.

Anyone came across this issue?

Cheers :D

Willie

    I did once - I took the tyre & inner tube out, held the wheel valve hole down and shook it until the tiny bit of grit fell out :)

    Cheers Chrissz, sounds like a plan. Ill try the vacuum first as if that goes well i dont have to bother with deflation and alll the rest of it but that should help if i can`t suck the little sods out.

    This is not something i tought woould happen, i was more interested in how you deal with water until i seen the little drain holes when i first got them.

    Great wheels so far tho, look really nice on.

    Thanks

    I had the same issue with grit - I think in wet weather the grit stuck a little to the bladed spokes, then slid down and into the fairing.
    I gave up in the end - couldn't hear anything when riding anyway. The weight penalty was a definite concern though :wink:

    Don't worry, the rattle will pale into significance when they fill-up with water in the rain!
    Make mine an Italian, with Campagnolo on the side..

    Hey monty dog, no worries with water here in scotland!

    Having sprayed the bike lightly for cleaning with my weed spayer thing, water does not seem to be an issue.

    If it was going to retain water i could do away with the second water bottle and fill up the wheels with lucozade. Would come in handy when i run out. :wink:

    :lol: Obviously they've improved things since the earlier models - perhaps the bigger spoke soles allow it to run out as quick as it runs in?

    The drain holes in the CF fairing take care of any water quite nicely :)

    Happys days, got the little stone out at last. Took half an hour with shaking and hoovering eventually got it out one of the spoke holes. The Aksiums are back on till i see the pink stones left behind by all the gritting are gone....probably never.

    Thanks for reading, cheers.

    Ive been looking for carbon clinchers - the conclusion I have come to is that these represent the best in terms of VFM\BLING\Reliability ? ......any thoughts

    I don't race - and I aint that fast 17mph over a hilly 25 - is a good speed for me - and I go on the clubs 'B' run - how practical will these be for a spring to october tyre ?

    i bought some of these last november and have only managed to use them once before the winter set in. First impressions were good, definately VFM for an aero clincher, not so sure about the looks as the carbon looks like it's printed onto plastic, weight.. bound to be better than the khamsins they will eventually replace. What i did notice was how the feel of the steering changed much lighter that felt really good - cheers
    All lies and jest..still a man hears what he wants to hear and disregards the rest....

    Hi Rollo,

    These are my first fancy wheels having upgraded from the Aksiums which came stanadard on my Kuota Kebel. The Kebel was an upgrade from a Trek 1.5 with the basic bontrager SSR wheels which at the time felt very nice. The Aksiums seemed to be a jump in quality again. Spin better and defo less flex than the bontrager SSR`s.

    The Cabones are a fair jump again. Lighter, stiffer and very pretty they are too :wink:

    I should point out that i dont race, i just enjoy going on runs with friends and quite like a bit of bling whilst doing so and these fit the bill nicely. Im not really any faster than you based on the 17mph you are saying, but i do feel that things are a little easier when things get moving with these wheels on. Ive got a timed lap i do with my cycle pals where we go round arthurs seat here in edinburgh so when the weather gets better ill have a basic figure on which to judge them. Ive only had them a month so reliability is not known. Value for money is good from what i can tell. Planet X were doing them for £600 a month ago and thats the best price i have seen.

    IMO the bling factor is very high, some people may think its a bit OTT getting these and not racing but its my last spend before i get married so its happy days before the joint account spoils it all. :D

    Happy hunting

    What do you think of these though ?

    Major difference is they are all carbon - they don't have a braking surface ....would they suffice for a slow 47 year old like myself ..mr 17mph chuffed ?
