What Our Gearhead® Experts Are Saying:
"This tool has saved me countless times on trail rides. Having both a CO2 inflator and every essential hex key in one compact unit means I don’t waste time digging through my pack. It’s lightweight, easy to stash, and gives me confidence that I can handle almost any trailside repair."
We never ride without the Serfas ST-131 Multi-tool CO2 Inflator close at hand. Serfas built this compact piece to cover everything from a loose bolt to a sudden flat, ensuring we’re never stranded miles from the trailhead. With 13 tools packed into a sleek alloy body, plus a built-in CO2 inflator, it’s the ultimate peace-of-mind companion for long days in the saddle.
Inside, we’ve got all the essentials—Allen keys, Torx bits, screwdrivers, and even a bottle opener for post-ride refreshments. Presta valve compatibility makes it easy to inflate and roll again in seconds. At under 100 grams, it’s light enough to disappear in a pocket or pack, yet tough enough to handle trail and road emergencies alike.
