The size options says 2-2.25 in, but the tech specs say 1.375-1.75", which one is it?

Insurance policy! Sick of walking my bike out when I have a flat or snap a wheel.

Inexpensive tube to throw in your pack for that rare tire slash your sealant won't handle. 2 to 2.5 pretty much handles all Mountain sizes minus Plus.

Great Cheap Tube

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

If you’re looking for a cheap tube to carry as a spare, look no further. Can’t beat the price on this!

Handles well

I don't really have anything amazing or negative to say. It works as one would imagine. I was a bit surprised on how much cheaper it was compared to other makes of the same quality though.

Great backup plan if you run tubless and find yourself in trouble when you're out on the trail.

Backup for Tubeless Tires

Familiarity:

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

I bought these as a backup in case my Tubeless Tires get a big enough puncture to where the sealant won't seal the hole. I'll just throw a tube in there, pump it up, and be on my way.

There when you need them

When you run tubeless you always will want a back up plan if you are to get stuck on the trail. They hold air and will work to get you off the mountain. Does the job.

Good Tube for the price. Picked up 3 or 4 of these so I never have an excuse to not fix a flat or take a ride. Running these on front and back and haven't had any issues yet

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.

Sam Broome

Just what I needed

Nice and cheap tube. Exactly what I was looking for.

Casey Sandala

On-Hand

I ride tubeless but always have some q-tubes handy. They do the job and are cheap enough to buy a few! Don't forget your tubes!

So far so good

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

They work

Familiarity:

I've put it through the wringer

They hold air and keep a tire inflated, so they do the job. Nice plus is they have a removable core.

q tubes have been super consistent for me in road, cross and mtn. I always keep a stash on the shelf.

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.

Neal Forbes

Tubes

They are black, you can put air in them, and you can go ride your bike. Whats not to love.
