Review on 🔧 Topeak Pocket Shock DXG Pump (2018): A Portable Solution for Efficient Shock Pumping by John Ghattamaraju

I ordered these because I needed a 340psi shock pump for my rear shock. It's a lot less efficient than the other two pumps I've had (although both are only rated for 300) but the kicker came after 10 minutes of pumping when this pump released all the pressure for no reason when I hit 330. 10 minutes later it happened. it again as soon as I had it above 330 again. On the third try, now 30 minutes later, I tried to just stop at 330, but due to the design of the pump, it releases so much air no matter how fast you try to spin it. It shocks me that he loses 20-30 psi every time. I ended up spending $3 less to get a Giant brand pump at my local store with a better design that doesn't lose all of the pressure when you take it off, that can do 400psi and actually holds that much and much more efficient It doesn't take all day to inflate a large shock absorber. Maybe mine was defective, but it's a terrible design and poorly made. Never buy a Topeak product again.
