BikeTiresDirect16g Threaded CO2 Cartridge (6-Pack)(Return to Product Page)

Bad does not pump up the tire fully maybe half if that

Used to of them to finally fill it all the way

Did not fill the tire it sucks not worth it

It is a CO2 cartridge- what is there to say

The BikeTiresDirect 16g CO2 cartridges are a fantastic value and will easily inflate your tire to 120psi. Have had to use them multiple times on rides. I would feel naked on a ride without having at least two in my saddle bag. Don't leave home without them!

Functional CO2 cartridge. Price is right.

These are a fantastic value and I buy them by the dozen. I chuckle when I see what one of these babies (with fancy labels) go for in sporting good stores. Yikes! When I flat I don't sweat it using one. When a buddy flats I don't mind tossing him one.

I don't use them as much as I used to since I started using gatorskin tires, but I still carry 2 cartridges on all of my rides.

It's a CO2 cartridge so all it needs to do is hold CO2, right? They've always worked for me. A highly recommend waiting until they are chosen as the daily special and stocking up on them.

I have a large case of BB gun CO2's and no use for them. I've read that some inflators can use them, this one wont, the 16g carts for this are larger in diameter and a bit longer than BB guns' more on that later. I ordered BTD Biketiresdirect generic 16 grammers and they work fine. I'm running 26 x 2.1 60 psi. It takes about 2 carts to fill a tire and i usually carry 3 of them for emergencies. Now for the BB cart part, I cut 1 12" strips from a cereal box, wrapped it around a BB cart with tape to increase diameter, threw a penny in the bottom of the housing to increase length. It works but not the best. Will only go that route for dire emergencies. BTD prices blows away my local shop.

Same gas, same size, same weight, same compatibility. Why pay 50% more for the name brand cartridge when this one works exactly the same.

just air. :)

In was a hot day on a not too great stretch of road. You know the sinking feeling that comes with a rear wheel flat. Fifteen minutes later with the help of on CO2 cartridge ( and Lezyne inflator) I was back on the way home. What's not to like? I carry two of them in my bag. Just in case.

Cartridge inflation is useful when you need save space, weight, and time. I keep a fresh tube and inflator system ready to go on my road bike that has scarce room for a pump. Otherwise, this is a commodity product that does what it's supposed to do.

Cartridges worked fine and were reasonably priced.

A frame pump makes your bike look ugly and a hand pump that fits in your pocket is frustratingly slow. Get yourself a good valve and pack a couple cartridges. Don't forget the ideal gas law and wear gloves!

They hold air and put it in my tire. What else can I say?

On our broken glass covered streets, these are a life saver. quickly getting me back on the road without the added energy expenditure of trying to inflate a tire with a mini pump after repairing a flat. Still a good tradeoff to sloppy tubeless obsession, which I've tried and given up on.

Does the job well. Compact and affordable in the 6 pack.

Work fine I've been using these for years. Never a problem

I have not carried a pump on my rides in years. These cartridges are the best value and do exactly what I need.
