Mounting mini-pump on frame I recently bought a mini-pump from Amazon, it was very cheap and,  so-far, I'm pretty impressed with the build quality. I never intended to mount it on the bike but then realised that it came with a thin metal "bracket" that attaches to the pump.

As you will see from the photo below, the pressure tube for the pump is actually housed in a separate plastic container connected to the pump itself:



If I attach the bracket as it is, the pump and the container will be protruding sideways outside the width of the frame. Do you think the manufacturer intended the bracket to bend once bolted to the frame so that the pump and tube are neatly stored within the frame profile? If yes, then what does the cut-out part of the bracket achieve in this scenario?

(Before you ask, the instructions don't mention the bracket and I have tried contacting the manufacturer but they appear to be another company who don't actually monitor the mailbox they advise customers to use.)
The metal bracket is designed to fit the lugs of a water bottle cage.  If you have a bottle cage, the bracket goes between it and the frame. If you don't, it can just be mounted directly: the lugs on your frame will already have bolts in them, to stop the rain getting in. In either case, you might need or want to bend the bracket a bit, either to give more clearance for your bottle or to move the pump more within the frame. That shouldn't damage the bracket, as long as you don't bend it right back on itself or repeatedly bend it back and forth.

Mine lives on my down-tube. Unless it sticks out a long way, your legs shouldn't come close to it and, in any case, the pump will be between your legs and the bracket. If you're still worried about slicing your leg open, use a metal file to round off the edges and remove any burrs. Actually, that would probably be a good idea anyway to avoid hurting your fingers when you need to use the pump.
