you’ve got it. Only issue is if your draper air hose is a bit chunkier than what the track pump head is designed round. A bit of grease and determination will get you there, though.
google “track pump head” and get a presta one that you like the look of. and the price of.
I wouldn’t get a topeak superchuck again. nicely made, but they don’t come off the valve unless there’s no pressure difference between the hose and the valve. Fine if you’ve got the valve stem in, you press the little button it does that for you, but if you’re getting the tyre seated 1st off with no valve stem in, you’ll have to let it all the air of the tyre before you can get the inflator head off the valve. Or yank it and risk compromising the seal.
Cheapy BBB worked better for me.
And actually, you need to cut the schraeder head off what you’ve got anyway, so do that and slide the hose over the valve. Works fine! Get it up and seated with the compressor, then fine tune with the track pump/thumb/pressure gauge if you need.
Worth trying before you recklessly squander £6 on a BBB smarthead.
