Black CO2 Inflator Presta and Schrader Valve Compatible Bicycle Tire Pump for Mountain and Road Bikes with Insulated Sleeve - No CO2 Cartridges Included, Quick&Easy

Used with 25g carts. Several times I used half a cart or less, tightened the valve closed, threw it back in my tool kit, and this inflator didn't leak a bit. This unit kept open cartridges sealed for weeks at a time. Smooth to open and close, the valve in this inflator is high quality.Screws easily onto my Presta valves, with smooth action, and no air leaked going on, nor coming off.The insulator is crucial, rounding out a great experience during application, and it fit 20g carts without issue.I keep slime tubes in the 700c 28 size tires of my shaft driven, IGH commuter. Recently on a late night ride home, in the final 3 mile stretch/climb, my front tire gave in, forcing me to the dirt shoulder. It was completely dead flat. Remaining straddled over the bike, I checked for thorns/etc., then lifted the front wheel and gave it good spin or three to distribute the slime. Next I grabbed this inflator from my bag, leaned over the bars, and easily screwed it onto the presta valve. I gently opened the inflator valve and my tire sprang back to life. Guesstimating 60 psi left a bit extra in the cartridge which is right where I like to be. Buckled my pack up, and I was back rolling in what was hardly over five minutes. Great feeling.Finally, after a year and a half, and about 24 cartridges, I had beat the cartridge receptacle o ring beyond function. Back on AMZ, considering a new inflator I decided to check this listing again only to be reminded of the 3 spare o rings stored on the device! Back to new in two minutes. This compelled me to write this review.This conservatively styled inflator has a thoughtful design, and has provided me with what I can only determine to be flawless functionality, and an optimal experience in field application. If only it was priced to provide maximum value.. Oh wait! IT IS! I'm very happy to have scored this great device.

Excellent, zero leaks under 850 psig CO2 pressure. Submerged under water and zero bubbles, no leaks. Normal CO2 cartridge pressure is 850 psig at 70 F. This threaded schrader connection is excellent. Note that most schrader valves are low pressure design, the one in the photo is a 4,000 psig design schrader valve from mcmaster carr.

I just received the inflator today and while I have not used it out on the road, I tested on my wheels at home to make sure it works and that I don't encounter any surprises; it worked flawlessly. I've only used the Proflate Elite unit and can affirm that the BriskMore is a much better quality piece of equipment.Below are my observations.1. threads securely onto presta valve resulting in no loss of C022. very simple and easy to use3. smooth valve control4. no air loss when removing the tool5. spare replacement seals for valves (nice touch)6. includes sleeve to prevent damage to hands during use (nice touch)7. takes up very little space in my seat bag (I use a small bag)8. works with 20g cartridges (i.e. used with genuine innovations cartridges), even though specs says 12 and 16g only. Can't speak for other C02 cartridges.9. light weight - 22gThis is a nice inflator and I would recommend it to my fellow riders if ask. The inclusion of the spare seals and sleeve is a nice touch that most companies would not include and charge a premium to acquire. I am going to purchase a 2nd BriskMore to replace the Proflate Elite I have in my mountain bike seat bag.

Works good. No issues

Perfect little C02 inflator. High quality aluminum machining. Lightweight and compact, perfect for a saddlebag and worth it's weight in gold. The head nozzle rotates independently so you can attach it to your valve, even if the C02 cartridge is screwed in first.

Quality Product

Went ahead and used a CO2 cartridge at home before putting in bike bag. Trial, air up on a few old tire/tubes at the house. Worked well on schrader and presta tubes. The little throttle valve worked just fine, was able to start and stop flow no issues. Bought this to replace a very old CO2 inflator that I never really liked very well. The addition of throttle knob make all the difference. Not saying it is the best in the world, but is a real bang for the buck. Sometime we carry a Blackburn mini pump and CO2, I would be confident in carrying only this and a few threaded cartridges. Have not used out on the road/trail yet, would seem to be just fine out there also. B

Added to a bike frame tool kit package. Needed light and small parts.
