Mini Bike Pump-7.3 inches 260 PSI High Pressure Fits Schrader & Presta Valve,with Glueless Puncture Repair Kit.DBLLXX Lightweight & Durable Aluminum Cycle Hand Portable Air Pump for All Cycle Tires

This looked like it would be a good little pump and when I first tested it things seemed fine. Here were the primary issues I had with it.First, the bracket provided to attach it on the bottle screws fits but the pump then sits too far to the side so it inhibits the pedals to turn. I couldn't see any other way of positioning it, so I ended up just putting it in a carbo bag under the seat along with my tools and spare tube. It's been in there since giving me a feeling of being prepared for the next flat.Flash forward to this last weekend when I had a flat. No problem I thought, until I attached the pump (presta valve configuration) and it promptly failed to do it's simple job. I attached it securely and checked repeatedly but found it was leaking air behind the valve attachment. It pulls out fully to make the connection to Presta configuration, then goes another view millimeters which causes the back leak of air.Queue lengthy walk to a cross road and a call to my wife to come rescue me.

tried it out. works good. only issue i have is its mounting bracket is specific to mounting under a bottle cage so its off center. my bike doesnt have one in a good place for the mount without interfering with the crank or pedaling. so i must keep it in a bag on the rack. i can see where this could be a concern if you dont use a bag.but then again why carry a pump if your not carrying a tool kit...seems very well made.

Not convinced of the high pressure claims. Haven’t tried the patches. Pump is great ifn you don’t have to pump a lot

Do NOT buy! I used it all but ten times before the tube began leaking air...aviod it unless you want to pump a tire before you realize its not pumping.

Pretty good

Not bad for the price. Just what I was looking for,

Installs very easy. But may not be that secured to its mounting clamo. Have not used it yet.

Holder is ok but pretty flimsy
