    Typical weight of a thorn resistant tube???

    Im wondering if anyone has weighed a thorn resistant mtb tube? What is a typical weight of a thron resistnat tube? I just went ghetto tubless and am wondering how much weight i knocked off my bike?

    They usually run about a pound (453g) give or take 50g depending on brand.

    that sounds high, doesn't it?

    does the OP mean like a Slime tube that is pre-filled with slime?

    So are you saying you went from a thorn resistant tube to ghetto? I have a TR tube in the rear and haven't had a pinch flat yet at 28 lbs with my 220 lbs+ and about 500 miles on it. Heavy, though. mtbr72 is close...it's about 1 lb+/-

    Nope...those things are tanks. But if you don't believe me, here is Performance Bikes Forte TR Tube, check out the weight under specs.

    No. It's like a regular tube only constructed of thicker rubber with the idea that thorns won't be as likely to get through to the air.

    I have been using these


    I searched all over for an exact weight but could only find shipping weight. (1.5lbs)

    I was running WTB Speed Disc Rims with Avenir TR tubes and Kenda Nevgal Tires. I decided to purchase two 20" BMX presta tubes and some cafe latex and try going ghetto tubeless. So far so good. I stretched the tubes over the rims and got the tires to seal with cafe latex. It took an air compressor to get the bead to seat, but they have held 45 psi for the last 3 days now.

    I took it for a spin lat night and tried to put some stress on the tires. Still good so far. Only time will tell. I am hoping i get at least 6 months out of them until i need to re-seal the wheels. From all the reviews i have read i think i will try going to the Stans sealant next, or maybe making my own concoction.

    I can feel a difference in the overall wheel weight though.

    Drop that PSI...45psi is way too much (and might not be safe), should be able to run 30-35 psi no problem and get better traction and actually lower rolling resistance.

    The ones I used weighed 600 gms on the dot.

    Same weight as the tyres I run fwiw.

    I'm using the Slime Smart tubes which are '5x thicker ' or something liek that , than normal tubes. They're definitely heavy but I haven't had any flats.

    Plan on trying ghetto TL at some point or using tires that have puncture protection with normal tubes.
