Price Point 700c Presta Light Tube
Price Point light mountain bike tubes are manufactured in the same facilities as more expensive name brands, but sold exclusively to Price Point. Tested and inspected to ensure they meet industry specifications at a fraction of the cost.
I typically buy 5 or 10 of these at the beginning of every season. You just cant beat the value, especially when they offer bundle packs! One word of caution: The stems are short - make sure you get the long stems if you have deep rims.
