What Our Gearhead(R) Experts Are Saying: "I keep this on my trail bike and fat bike-it's powerful enough to fill big tires fast, and the magnetic hose system is seriously slick. I love that it's all internal until you need it, and the pressure gauge helps keep things dialed."For riders who need dependable volume on the trail, the Crankbrothers Klic HV Gauge Pump delivers serious air power in a sleek, compact package. Designed for high-volume tires 1. 8 inches and wider, the HV version moves air quickly while packing down small enough to mount to your frame or toss in a pack. A hidden magnetic hose and integrated pressure gauge make inflating precise and easy, while the folding, locking handle gives you leverage when pumping up big tires. The presta/schrader-compatible valve and bottle cage mount round out a thoughtful, travel-ready design that's as functional as it is minimalist.
