Fatty Object High Volume CO2 Inflator

$22.30
As of 2026-10-21

The Fatty Object is specifically engineered to meet the demands of high-volume tires found on fat bikes and plus-sized mountain bikes. Constructed from durable alloy, this inflator is built to handle the larger CO2 cartridges required to fill high-capacity rubber. It provides a fast and efficient way to get back on the trail after a puncture.

This model features a robust design that accommodates Presta valves, ensuring a secure fit during the inflation process. The oversized control dial is easy to operate, allowing for a steady release of air into the large tire casing. Its specialized build ensures that the tool can withstand the freezing temperatures often associated with rapid CO2 discharge.

For winter cyclists and trail riders, this tool is a vital part of a repair kit. The alloy construction provides the necessary strength to survive rugged outdoor environments and frequent use in varying weather conditions. It bridges the gap between standard road inflators and the heavy-duty needs of wide-tire enthusiasts who require maximum air volume.
