    Nino - What tubes are you running in the bike? Do the schwalbe fat bike tubes hold up or would you recommend sticking with standard tubes?

  • luckynino

    12/1/2015 8:02 AM

    I'm using those Schwalbe Fatbike tubes all year long in all my wheelsets. I guess it depends on the terrain you ride in but over here they hold up really well. I don't compromise in tire pressure either. I'm running as low pressures as i did before.. Those tubes weigh just 380g/pc. so that's easily 2 lbs less than your typical heavy-duty MX innertube.

    Awesome! I ride regular loamy/sandy motocross tracks here in the UK. Very, very rarely get punctures so I'd love to give this ago. As you said, potential 2lbs saving for very little money. What size are you running? 26" x 3.5 - 4.8 both front and rear?
    Thanks for your help

    Yes-same size front and rear. It makes some small wrinkles but that's no problem at all. There is a whole thread with more details and pictures on my bike on thumpertalk here: http://www.thumpertalk.com/topic/993917-my-new-cr-125-afs-aluminium-framed-mugen-powered/

    Interesting that someone would go to these lengths to save weight and then cover the bike in heavy graphics

    You are right but in the end it still has to look good. At my age i don't do it for any championship races anymore but for the pure joy of it. And these graphics are at least lighter than the ones i used before. So i was still removing weight by doing so (-55g total). And if you look closely you could see i also added a steering stabilizer and PHDS bar mounts which both add some weight BUT in the end it is also the performance that counts and these items do awesome. I was not after a record weight. If so i would still put lighter parts...I just wanted to reach the lower weight limit which i succeeded in. By putting my usual handguards and exhaust protection i'm just at the lower limit which is perfect for me. This also includes the graphics.

    Hey Nino! Thanks for including MOTO STUFF in your incredible builds. Very inspiring! Can't wait to try out the steering dampener you turned us onto- (It's on back order at the moment......) PS- 2nd 270mm Blade is on the way!
    BRAAPP!

    Thanks - your brakes are really awesome ! You will be surprised by how much the steering stabilizer calms your ride in the choppy stuff and at speed.
