• I inherited a set of tubeless disc wheels on a new bike recently and am having trouble keeping air in the front. It sounds like air is escaping from the valve hole. I've checked the tape and all seems fine, I've checked the valve and that seems okay, i've tried inflating with a track pump and CO2. Nothing seems to work.
    Any other tips?

    Or do I just order a new set of IRC's? If so, which ones? I like the sound of the road lites. How do these compare to 4000s ?

  • Road lites are like the gp4000s but more comfy and tubeless. They last longer too. The unexplained leak could be the valve core. Replace it.
