Better than a Tube Top

  • Familiarity: I've put it through the wringer

Are you tired of walking your bike after missing that tranny on your favorite jump? How about after those darn rattlesnakes take a bite out of your current tube?

Do you suffer from flat tires due to gnarlyness, shredfests, or send offs?

Or perhaps you burped out all your tubeless sealant while scraping elbows on that berm?

Regardless of the why, the solution is now here! Get your spare tube now!

(Fine Print: Prices subject to change. I am not responsible for picking you up after tearing your spare tire so please don't message me to do so. No tube is indestructible. If you keep shredding your tubes, please go tubeless or run higher pressures.. If that doesn't work, then you're probably destroying your rims as well and have other issues. Please remember to spay or neuter your pets.

Gravel Guts!

    Here in Kansas we ride lots of gravel. The flint hills are notorious for eating tires and tubes. Just did a 67 mile ride and not one problem. Sand burs are another pain on the road , no worries. Continental 29er tubes fit my Trek Fuel EX 7 - 2.0 gravel tires great. I will be buying a second set for my 2.30 dirt tires and see how they hold up to our rocky terrain on the trails this winter. I have recommended them to all my friends.

    Long Stems for big rims.

    • Familiarity: I've used it once or twice and have initial impressions

    Lots of the current super-wide rims (think Enve M60, Ibis 941, and Industry Nine Torch) are also pretty deep. Most people riding them are running sealant rather than tubes, but these are the ticket for spares since they have 45mm valve stems. Tubes with shorter 35mm valve stems don't leave enough valve to get a pump or co2 inflator on.

    Always carry a spare

      I have switched my mountain bikes to tubeless, but always carry a spare one of these just in case I get a puncture that doesnt seal. A couple of other things you may want to consider purchasing are: and

      Fine tubes

      • Familiarity: I've put it through the wringer

      I've been riding Park City trails a lot lately, and just barely swapped over my wheels to a tubeless setup, so I've been relying on good tire/tube setups for the past three months. The trails here are pretty rocky, and I do every so often get snakebite flats from hitting jagged boogers straight on. These tubes have been a life saver on a few occasions when I'm 15-miles out from home. I've flatted two (2) tubes that came with the bike, and one (1) of these after barreling down a rock garden at ~25 mph.

      Nothing fancy about them, but they work as good as the others. I'm not a tube geek, so don't ask me about weight.
