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.

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.

Be Prepared

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

Sometimes you just need to plan for the worst....I have tubeless tires, but got these as a back-up just in case I experience one of those "blow out" things or a popped tire of some sort. I grew up on tubed tires, so I know they are reliable, and good to have around. The Q-Tubes 27.5in Presta Mountain Tube are a great choice as they are solid and won't break the bank!

Tubes?

  • Familiarity: I've used it several times

As others have mentioned, it's 2015 and tubes are for emergencies. These do a great job of padding my camelbak without crushing my piggy bank. I have had to use them on occasion as I have used this exact tube for a few years now, and they have done great so I continue to trust them as my way out if things go wrong.

Just In Case

    Just got my first 27.5 and while it's tubeless I think it's important to always have an extra just in case. Q-Tubes have been quality in my experience as well, just make sure to regularly check your tire pressure.

    Always have one

    • Familiarity: I've put it through the wringer

    Even with tubeless, I carry a spare tube, just in case. And it will work on any wheel size (29/26) in a pinch on the trail, so I am generally the lifesaver in the group!

    650b Tube is a rare breed

      I bought 2 of these for my Wife's Santa Cruz Bronson. She runs tubeless but if she slices her tread beyond a sealant fix, she has one of these tubes to throw in there. I was recently on a ride with a large group of people and one of the guys tore through his 27.5 tread. A bunch of people had spare 26 and 29er tubes but no one had a 650b. Bummer.

      For future reference Pete, the 26 tubes will easily fit the 27.5 wheelset.

      Will these tubes work for a 2.3in. Tire?

      Will these tubes work for a 2.3in. Tire?

      These tubes are recommended for tires up to 1.75in. I would recommend going with a tube rated for 2.1-2.35 for your tires.

      I am sorry to say that it doesn't look like we currently have any in stock, but I have had great success with the Kenda branded tubes as they are the same as Q tubes.

      27.5 = 650b

      • Familiarity: I've put it through the wringer

      Q-tubes are a staple in my pack and at my bench. Great value and performance. Now that 27.5/650 is here to stay, I had to stock up on a few.
