Found a Lezyne Pressure Drive(small) and Topeak Racerocket HP available online locally. I’ll just get one of those two. Anyway, i emailed Zefal and here’s what they said:
“ The FC02 has a 18mm piston diameter (the same as Air Profil Micro and XL). Depending on your strength, it may be enough to inflate to 6~7 bar (with equivalent diameter, the pumps with flexible hoses may be a bit harder at high pressures than direct connection ones).”
