Specialized - Air Tool Big Bore - Bike Pump

The Air Tool Big Bore Pump is a robust solution for fat and semi-fat tire bikes, especially tailored for backcountry winter fat biking. Here's a breakdown of its features:

1. Massive Volume-Per-Stroke: The pump boasts a high volume-per-stroke, making it efficient for inflating fat and semi-fat tires with fewer strokes, which is particularly useful in cold conditions where efficiency is key.

2. Winter Glove-Friendly Head: The head of the pump is designed to be operable even with winter gloves on, ensuring usability in harsh winter conditions commonly encountered during fat biking adventures.

3. Oversized Schrader and Presta Head: The head is designed to fit both Schrader and Presta valves without accidentally removing valve cores. This versatility is convenient for different types of tires commonly found on fat and semi-fat bikes.

4. Flexible Hose Attachment: The inclusion of a flexible hose attachment allows for aggressive pumping without risking damage to valve stems. This feature adds durability and ease of use to the pump.

5. Inverted Barrel Design: The design of the barrel allows for high volume in a compact size, making it easy to carry and store, which is important for backcountry biking where space is limited.

6. Coarse Machined Aluminum Barrel: The barrel is machined with a coarse texture to provide extra grip, ensuring a secure hold even in wet or snowy conditions.

7. Water Bottle Boss Mount: Similar to the previous pump, this one also includes a mount for attaching to water bottle bosses on a bike frame, enhancing convenience during rides.

8. Pressure and Volume Specifications: The pump has a maximum pressure of 50 PSI (3.5 bar) and a generous volume-per-stroke of 90cc, specifically tailored to the requirements of fat and semi-fat tires.

Overall, the Air Tool Big Bore Pump is a well-engineered and practical tool designed to meet the unique demands of fat and semi-fat tire biking, especially in challenging winter conditions.
