They Hold Air
- Gender: Male
- Familiarity: I've put it through the wringer
These tubes work as intended. I have ridden over many miles and some nasty stuff with these and they have held up well and seem to be pretty resistant to flats. I go on a couple rides a week when trials are free of snow around Utah and one 4-pack has lasted me well over a year. Plus at the sale price it's an easy way to stock up and always have spare tubes on hand.
