Q-Tubes

Cyclocross Tube

The "Q" in Q-Tubes is Quality Bicycle Products -- the 10,000lb wholesale behemoth of the bike biz. They're produced by Kenda for QBP so you know they're high quality and will work just fine in your bike. The presta valve stem is 48mm long and should allow easy inflation with most low profile semi-aero rims. And at 125 grams each, the Q-Tubes 700c x 30mm Cyclocross Tubes are still plenty light so as not to hamper your barrier bunny hopping ability.
