For gravel applications, a mountain bike mini pump is the best solution. The wider body delivers higher volume with less effort than a road pump. The MSW Airlift 220 has a full alloy body with cross-hatch texturing to ensure you get a firm grip even with wet or muddy gloves. A 5" hose extracts from the body to provide flexible access to the valve stem. The smart head works with both Presta and Schrader valves, and pumps up to a more than ample 80 psi. The pump include a mount with 4mm bolts for tidy storage behind a bottle cage.
