Be your own hero.

Given the rapid arrival of 27.5-inch wheels to the marketplace, the likelihood of your LBS or trail-side guardian angel not having the corresponding tube is pretty high at the moment. For this reason, we recommend grabbing fate by the horns and stocking up on the Q-Tubes 27.5in Presta Mountain Tube. After all, it's better to be prepared then to be stranded.

The Q-Tubes 27.5in Presta Mountain Tube is available with a 32mm Presta valve and features a width of 1.375 - 1.75 inches.

Tubular tube

  • Familiarity: I've used it several times

Great tube. Holds up well and performs like it should. I use it as a backup on rides and it is light and smal enough to put in a small pack. Definitely would recommend it.

wish the stem was a little longer. Great tube for the price with a removable valve core!

Save Yourself From A Long Walk

    Most people are using a tubeless setup but it is still essential to carry a back up tube in your pack.

    Do yourself a favor a buy a few tubes to save yourself a long hike back to the car.

    You won't be dissapointed

    • Familiarity: I've put it through the wringer

    For my bikes that I still run tubes in these tubes are my default. I still much prefer running tubeless tires over anything with a tube but with proper tire pressure these tubes will hold up to mostly anything and are always nice to have as a backup.

    Also as some other commentators have mentioned, these tubes will fit in your friend's 26 or 29 wheel in a pinch if they forget to bring a spare tube.

    Gets 'er done

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

    It's exactly what you'd expect from a spare tube. Never travel without one because his little buddy will save your bacon when you send that rock garden a little too hard.

    Great Tubes

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

    Great Tubes for when you need to replace a tube, or in my case, get home after getting a flat on your tubeless setup.

    Get's the Job done

    • Familiarity: I've put it through the wringer

    Rarely have to use these things anymore, but good to know you've got a reliable tube on hand when you need it. I've used this brand on several occasions and they've gotten me home safe. Good price too.

    Consistent quality

    • Familiarity: I've put it through the wringer

    I've bought dozens of 26" and 29" Q-tubes, and the quality's always great - never gotten a dud. These continue the trend. They'll work fine in tires bigger than the recommended size.

    back up

    • Familiarity: I've used it several times

    I've stashed one of these in my pack as an emergency back up. I've also had to use these when I'm trying to seat new tires on rims. When all else fails, but a tube in and leave it overnight or a few days to help the tire seat.
