Ok, so had some time to spare and 3 mm aluminium sheet so made 2 aluminium tyre valve nuts.

The thread was cut using an old tyre valve, filed down to a taper and 4 slots cut.

Don't have scales that go light enough but the 2 brass nuts show up as 2 g, whereas the 2.0 aluminium nuts show up as 0.0 g.

(every little helps!!)

    It is important to keep unsprung weight as low as possible. Like I said, I had time to spare so other than sitting watching grass grow, this was more productive. and give me a psychological advantage over someone with brass nuts. 8)

    Surely having big brass nuts is better than having little mincy alu ones for a sport like MTB though :wink::lol:

    Surely its better just to empty your nuts before a ride, that should save some weight.

    I'm sure I read somewhere once about a team leader who got a team mate to cut off a toe to save weight. Maybe you should try that route?

    If you let all the air out the tyres, that will save weight.

    Maybe you cuold have the bars/stem/frame/steerer sealed and evacuted as well?

    That's only extreme if you cut off some fingertips while making the things.

    ^^^ I did go riding, and well, the difference was quite extraorodinary. 8)

    (I am sensing quite a lot envy over my lightweight valve nuts) :P

    And you weigh close to 100kg?

    I'd start looking at the body part removal route :-)

    I'm confident if you'd spent the time riding initially, rather than making these, the extra fitness would be significantly more advantageous than the weight saving!

    You could lighten them further by drilling a series of holes all the way round them. Or you could try using unobtanium, its much lighter.

    Having a shave in the morning could probably have saved the same amount of weight!!

    Still, no point knocking it, you had spare time which you could have sat on your ar$e and you did something you enjoyed. I am trying to fix and clean all my bikes at night at the moment to keep away the January blues have been leaving me in front of the TV eating crisps. Good effort!

    Could you make my an alu stomach to replace this even heavier one than usual that I've got just now!?!?!

    You could just run around the trail without the bike. That'd save a lot of weight.

    AWESOME! Love it! full marks for dedication!



    Some people don't seem to get it... it's not really about the weight, it's just a fun thing to do, and a productive way to waste time.


    very neat.
