    Can you see where the leak is. I'm assuming it's taped, tyres seated correctly and has sealant in.

    Most likly not getting it to crack on and seal with a track pump.

    Those bont wheels are absolutely terrible to get a seal on Had a Madone with them a while back

    I suggest taking it to someone with a compressoror a decent shock pump

    Follow up, got a lend of a small compressor this morning got the tyres pumped up to 60psi, but just checked the tryes and they are soft, tried spraying soapy water around the tyre bead and valves but i cannot see or hear any leaks, anyone offer any help.

    Pump it to pressure and immerse the wheel in water, either a bath or something similar. This should show up the leak.

    Pump them up to whatever the maximum is for the tyre ,60 as a maximum is still quite low ,especially with those wheels ,if i remember right they unseat when deflated normally too .
