Benefits of latex, (lightest tube I've found at 48g, good volume expansion)
About as puncture resistant as any other race-lite tubes
Short stem, removable valve cores
STRETCHY - Once they start stretching out, which happens after the first few hundred miles, they are quite finicky to install. Your best bet is to go slow, use some sort of talcum powder and situate the bunched up tube sections around the rim such that you can air it up and reposition as you go.
For repairs, I've used the Park Tool adhesive patches with limited success (they will come off over time like any stick on patch), but have found the vulcanized patches to hold best.
I basically only use these for race situations anyway.
Thank you for your feedback.
