    Ordinary or light tubes

    How does a tube weight affect the sturdiness of a tyre? I have Schwalbe Smart Sam 2.25 tyres with light Impac AV14 tubes (about 120g each). Is there any sense in installing ordinary tubes instead (about 200g each) or will I just increase the weight of my bike?

    You will just be adding weight. I always run light tubes.

    If you experience pinch flats frequently then maybe consider a heavier tube, or converting to tubeless.

    I run nobby nics and regular tubes. Light tubes will save weight, but are more prone to damage do to the thinner material. If you can run thin tubes and not have an unacceptable rate of flats stay with them.

    you can also fill the tube with any tubeless sealant and it will make it last a lot more

    Are your light tubes doing something to bother you?

    For me, for as little difference in price as there is, this is one of the places I choose to save a little weight. I could swear they roll a little nicer too.

    Re: Ordinary or light tubes

    Tubeless are overrated unless you ride in an environment where you get many flats. Been there done that.

    Light tubes is the best $/gram weight savings you can do. However, it can be annoying because they go flat quicker
