Tried to inflate a tyre with this combination tonight and had to give up and put an inner tube in. It's my son's bike which he's not had long but I'm pretty sure we've topped up the same tyre with a track pump but I was having no joy tonight with my oneup pump which has worked fine on my other bikes for the last year or so. Was I just being impatient?
I had the same combo and the same result. Changed to Peaty’s high flow valves, all sorted.
Just checked in the garage as I’ve had this combo for ages. No issue at all here, I just have to shove the pump on until it’s starting to cover the logo and it pumps just fine
Both front and rear valves on mine were blocked with sealant. Would go up with a track pump but not the Oneup.
I know Fillmore valves were redesigned because they didn't work with OneUp pumps so 76 valves might be the same if the are smooth around the top rather than extended threads
76 valves are a licensed design. Plenty of others use the same, including Halo and the bontrager ones designed to retro fit on regular presta valves that I am currently using.
They fit poorly on my trail pump and my track pump, so I'm changing them for fillmores too.
I've just ordered some old fashioned tubeless valves as I have a packet of spare presta cores and I've never had a problem with them on my bikes.
I converted all my bikes to Muc-Off Big Bore Lite valves, they're brilliant once you remember to close the valve before taking the pump head off the first couple of times.
