Blackburn Airstik Sl Mini Bike Pump

I would give it 4.5 if I could. This pump is light and mounts perfect on the bike, very discreet. Just tested it for my upcoming trip. I can't take co2 on the plane and wanted to leave my large stand pump. I ride 700x28 tires at 75/85 psi. I deflated each tire to about 30 psi. It took about 350 pumps for 75 psi and 450 pumps for 85 psi. And the last 10 psi were very very hard. I did end up sweating. And actually I hadn't realized but my right hand palm is cut.In the end, it did the job. The seal is perfect, you do have to hold it tight on the higher psi. I purchased this one because I didn't want a twist one that could untwist a presta valve. Also because it's very small and light. The pump seems high quality but there is no way you can use this to pump 100+ psi yet it's rated to 160. That is why I would take off a star. The reason I didn't was because you can't expect such a small light weight pump to do so. I am still going to ride with my co2 cartridges and use this as only a back up. And I might take my large stand pump and use this for flats.

This pump is nice and small. I got the black version and I am impressed with build quality because the images do not do it justice.

The pump works suprinsigly well for such a small pump. Good service. Item arrived on time.

This is a review of the Blackburn Airstik SL versus Topeak Micro Rocket AL. Same price, same size. I bought one of each (straight purchase, no received-for-evaluation hanky-panky) because I have a few bikes that need saddle bag size pumps. I also purchased the Birzman Mini-Apogee pump (not from Amazon). I'm testing performance with Presta type valves. For this test I'm pumping up a high pressure road tire. But I'll use these on road or MTB.Seal:Winner: Blackburn seals well with a push onto the valve and no leakage, either connecting or removing.2nd: Topeak seals while pumping, but loses air both pushing on and pulling offLast: Birzman - it's slide clamp mechanism is less than intuitive, and it still leaks air coming off. It is a compromise because it supports Schrader valve as well.Quality:Winner: tie Blackburn and BirzmanLast: Topeak - as mentioned by other reviewers the aluminum sleeve was loose on the piston end. I glued with rubber cement. You should not have to do this with a new product!Ease vs Volume: (there is no clear winner; this is a physics tradeoff)Higher volume, harder force required - BlackburnIn-between: BirzmanLower volume, less force required - TopeakSmall Size:Winner: BirzmanTie for 2nd Place: Blackburn and TopeakAdditional Comments:I had frame pumps back in the 80's which would seal fine on a Presta and pop off without leaking air from the tube. Why is this still hard to accomplish?

It surprising how a little pump can inflate cycle tyres up enough to get you home. it has a nice feature where you can attach this to your water bottle mount and there is a secure strap to keep the pump safe and secure. Feels a sturdy pump and pleased with purchase.
