hi been toying with the idea of drilling out my crossride rims(the internal box section not externally) to try and save a bit of rotational weight......has anyone done this, we used to have drilled rims when i used to ride trials...... :D

    i would say its a bad idea. that material is there for a reason. likely to make it very flexy and weak. but its your rim not mine, do it if you want

    also, unless you did it very accuratley, it would make the wheel unevenly weighted, and would end up slower

    round file will be fine..many of my friends did,,even on a DT Swiss wheelset..
    and they're fine..

    no, he wants to drill mor holes in the rim between the spoke holes so same weight, not enlarge his valve hole.

    NO idea how this makes sense... the "weight saving" is negilable over tubes!

    What Josh said,

    If you want lighter buy lighter rims.

    Yeah but then you have less rolling resistance, increased grip, and the time saved from not stopping to fix punctures..

    If you remove material from any part of your bike you will invalidity your warranty and also put yourself at risk of a catastrophic failure. If you want lighter wheels it will mean spending money no other way.

    Or...

    Instead of heavy, heavy air, inflate you tyres with helium..

    And you will fly down the trails..

    Wait.. Helium is quite flammable isn't it.. And rotors get very very hot.. Then if you puncture, not only will everyone talk in silly voices, but your bike might explode.

    AWESOME.

    Nope that is Hydrogen.

    Helium is inert.

    The propane is only used in the burner though, the stuff in the balloon is 'hot air' heated by the propane (hence the name), which is less dense than cold air.

    And to the OP, don't drill holes in your rims, it's not a good idea. Use lighter tyres.

    Agree with bigbenj, the weight saving (if there is one) from tubeless will be minimal, the only reason you'll be faster with tubeless is because you're not stopping to mend punctures.

    Not necessarily. And you can still puncture.

    Pfft Hydrogen is perfectly safe,its when you mix it with oygen you get a problem :)

    Most large HV generators are filled with the stuff as coolant

    If everyone thought like this the wheel would never have been invented. Let the man be creative!*

    I remember having factory drilled rims on a BMX, long time ago. I'm sure the rims were built with this in mind before they drilled the holes though...
