Air Tool Flex Pump

Delivery Icon

We deliver! Just say when and how.

The Air Tool Flex Pump uses an inverted camber design that allows for quick fill-up on mountain tires, yet it can still reach the high-pressures needed for road tires.

How do I successfully remove this from the tire?

I have this pump & successfully attached it to the tire, inflated the tire with no issues, but when I go to remove the pump from the tire ... it takes the entire Presta stem off with it & deflates the tire entirely. I've been jackin' around with this for over 2 hours & about ready to throw this pump right into the garbage. I noticed a couple folks managed to inflate the tire successfully, but I can't find ANYONE who knows how to disconnect the pump without removing the valve. If you know how to do it ... please educate the rest of us.

A bell pump from walmart would have done better

Awful pump, poor seal on a presta valve after 15 minutes of pumping, could not reinflate by 700cx43 gravel tire. Did no better gripping the valve stem of an inner tube with air leaking around the valve and noty being able to get any of the "30cc" per pump into the tire. Extremely dissapointed in a company like Specialized putting their name on an unreliable and poorly designed piece of critical equipment. Being stranded on the side of the road because you thought you had the right equipment is the worst feeling. Shame on you Specialized.

Screws/Pulls out Presta Valve Bodies Like a Pro

Specialized pump on practically brand new specialized tires on a specialized bike and this thing won't get an air tight seal until it's also got a death grip on the valve body threads. So when I unscrew it to get the damn thing off it also unscrews the valve bodies and causes all the air in the tube -- all of it -- to come rushing out because there's no valve body in the thing any more. I'd return this pump for a refund if I could. If it didn't do this I'd give it full marks. I was happy with this pump until it started doing this. But a pump that does this is not a pump anymore.

Would Recommend?

Best tiny pump for medium sized tires

A hose is the first requirement for me. Check. Next is a valve attachment that seals tigh but doesn’t remove my valve core when I’m done pumping. Check. Finally, for a mtb or gravel tire, you don’t need high pressure, so “low gearing” ie a high volume per stroke is great. I am impatient though, so I will move this too my gravel bike, and try the Big Bore mini pump for my mtb.

Would Recommend?
Yes!

screws securely onto your valve stem

Out on Honeymoon Island's Pelican Trail, I had adjusted my fat tires down to 5 PSI for a deep sandy section, and was using my Specialized pump, trying to firm them back up to 8 or 9 PSI for the hard-packed bits. Hundreds of pump strokes later, I had managed to LOWER the pressure down to 4 PSI. Air bled out faster than I could pump it in due to the failure of the nozzle to seal onto the valve stem. I was about to throw this pump away and complain to my bike shop, but searched ""Specialized 30cc bike pump won't seal"", just in case someone else had solved my problem. One or two negative reviews here pointed out that the pump SCREWS SECURELY ONTO YOUR VALVUE STEM. Why didn't I know this? DOH! Testing back at home proved that the valve core stayed in stem. So, I am keeping this little guy! Do not expect speed with a 30cc barrel, but this pump is Solidly Built, fits in my saddle bag, and gets the job done. I might try the MTB version if this one wears out, but I like the short retractable hose on this model, which provides just enough slack to prevent back-and-forth stem movement. The best pump is the one you have with you, and the Air Tool Flex Pump, at 9"" x 1"", travels very easily.

So far so good

Works well so far. I really like that the side-mount fits behind my water-bottle carrier. Pumps seem to come in for a lot of bad reviews - I once had a Silca in the 1970s, a work of art, that shattered - but this does look really well made, works smoothly, nothing leaks or rattles. If flats are a way of life, strap a floor pump to your bike - we had a Warm Showers guest who did that!
