Alienation Feather-Weight TPU Tube

$25 per tube and the lightest Ive ever used but the valve stem leaked before I could try them out and it cannot be repaired according to Alienation. Bummer these are so fragile but tubes should be tough.

I suggest you buy a good floor air compressor that is rated over 120 PSI with a connector that allows you to screw on to the Schrader valve and leave it connected until its at the PSI you want. Bending and moving the valve after its installed to inflate it caused a leak. Some of the Ares tubes started leaking air at the base of the valve and one TPU tube went flat easily from a small puncture. The 3 brands of light tubes I tried are all very light but delicate and pricy. I have the TPU and regular patch kits and a can of Flex Seal liquid rubber I spray over the patch.

I bought 4 of this tube and 3 got problems with the valve, its like take it off the material around it and you loose air. for the price it doesn't worth.
