buy em in bulk

I've put it through the wringer

just buy a bunch, then you can not stress when you have to give one out, on the trail or road. The box lasts me about a year and we have 6 riders in our family.

Never Run Out

I always carry one of these with me. I prefer to have the 20g over the 16g when inflating 27.5 tires. Nice to have plenty on hand.

Good value

The bulk Portland Designs CO2 works well and keeps gets you back rolling quickly after a flat. With the bulk buy, you won't feel bad about taking enough with you to be sure that you don't run out even if lady luck isn't on your side.

Best Value in Bulk

If you use C02 on the go, you're going to run out of cartridges eventually. Save yourself the hassle later, and buy in bulk today. Worth it in the long run!

Portland Design Works C02

I've used it several times

I liked the idea of these being sold in bulk. Because I ride alot and it's nice to always know you'll have something around to fix a flat. less trips to the store means money saved and more biking. Goal!

Do yourself a favor and bite the bullet now. You're going to use them eventually right? As for performance, they are metal cylinders filled with co2. They arrived full of co2 and have not exploded in my backpack yet so that's pretty much all I can ask of them. They are definitely very shiny, so if you're into that you'll be extra pleased with them. Don't pump like a chump, show up with co2 cartridges to spare.


Do you have 12g refillable co2 crtrdgs?
