Review on Pump Upgrade Hose Clamp Presta by James Townsend

I was looking for a bolt on a presta valve for my floor pump to get my bike to 100psi without slipping. There are threads inside that fit the Presta stem, but I was only able to hook them in by removing the cap, including the rubber grommet it contained. I didn't try downloading that way because it just looked/felt wrong. I inflated my front tire by simply sticking a stick through the outer cover/seal and found that the way the stick works is pushing the stick shaft in and getting air into the tire. At first I didn't, and the pressure in the chamber stabilized and the tire wouldn't inflate. But it worked. I had to try the rear tire a few times until it hooked and locked securely and also let air in the tire and while I still didn't feel like I got it right I was able to inflate to 100psi, but interestingly enough I couldn't pump past 100. Maybe at 100 the inside of the stock will be pushed into the stock and shut off the air supply. I do not know. I just wish there were guides or videos to make downloading easier and more reliable.
