I'm not convinced by the clams from the mini pumps. I've had them before and have always struggled to get much above 80psi
So, FWIW, I've ditched mini pumps and now have a Topeak Roadmorph. Easily gets to 110psi, has a decent gauge (I've tested it against the track pump). It's light but, of course, it's a bit bigger than a mini. I've carried it in my back jersey pocket plenty of times but I now attach it to the top tube. It comes with a connector and Velcro straps and is very secure. Depends on how you feel about a pump on your bike I guess. I couldn't care less
