Blackburn Mammoth CO2’Fer Bike Mini-Pump

The pump work well. It just takes a few pumps to climb 1 PSI. A bit big and heavy to carry on a ride. I use it before my rides.

i really like this pump for my DH riding. i love the option to use the CO2 or use it manually. it’s small and light and fits in my backpack with ease. it also has the option to mount it on a frame if you like to do that.

Great combo. Small and light.

Nice compact pump. Looks great on my bike.

DO NOT BUY THIS ITEM please Use your money for a better use! This item would not come off my Schrader valve it got stuck, and it’s hard to pump air into it!!! I legit spent an hour trying to get it off my tire I had no choice but to rip it off my bike😐 GARBAGE 🗑🤬
