My last bike experience was about 56 years ago. I now want to inflate the tyres of my grandchildren's bikes. I have a steel stirrup pump (floor pump) with presta and schrader orifices in the chuck. I'm in the UK, where everything seems to be schrader. I'm assuming the schrader orifice is the hole without a poppet.
Problem: the chuck is too big to enable the lever to be extended when connecting to the valve on the wheel. (For an adult bike, the lever in the neutral position would be at right-angles to the valve. In the working position, it would be inline with the valve.)
Question: I read about "flexible extenders" in relation to kids' bikes. (In the old days, this thing lived inside the handle of a straight pump.) I'm wondering if a schrader flexible extender would do job? For example:
If the above monster link fails, this link might work:
If the answer to my question is "yes", do I simply push the left-hand end shown in the link into the schrader hole in the chuck, and extend the lever?
