Notes from buyers
The Cloud Cap pump is the perfect size for my gravel bike frame and the CO2 head is a great backup.
I used the Fatty Object on my winter rig and it handled the large tires without any issues.
The alloy construction of the Shiny Object feels very solid and it threads onto the valve perfectly.

Gravel and Trail Focus
The Cloud Cap and Ninja models are sized specifically for the air volume needs of gravel and mountain bikes. They provide more air per stroke than standard road pumps.
CO2 Integration
The Shiny Object and BARkeep models focus on rapid inflation using CO2 cartridges. These are ideal for racers or riders who need to fix flats quickly.
Material Durability
Using alloy and chrome ensures that the inflators do not crack under the freezing temperatures of discharging CO2. The metal construction also resists trail debris.
Specialized Fat Bike Tools
The Fatty Object is a dedicated inflator for fat bikes. It is designed to regulate the high volume of air required for oversized tires.
Portland Design Works Questions
Do these pumps work with both Presta and Schrader valves?
These models are primarily designed for Presta valves, which are standard on most gravel and mountain bikes. The alloy heads ensure a tight seal during high-pressure CO2 release.
What is a hybrid pump and CO2 inflator?
A hybrid tool like the Ninja or Cloud Cap allows you to use a CO2 cartridge for speed or the hand pump for manual inflation. This provides a backup if you run out of cartridges.
Are CO2 cartridges included with the inflators?
The inflators and pumps are sold as the hardware units only. You will need to provide your own threaded CO2 cartridges for the inflation feature to work.
Is there a specific model for fat bikes?
Yes, the Fatty Object is specifically designed for the high-volume requirements of fat bike tires. It allows for efficient air transfer into larger tire casings.
