They are saying most high-end pumps are +/-3%, and a few low-cost ones are as dangerous as +/-9%.
Additionally they declare {that a} 1psi distinction in stress means 1-watt change in rolling resistance. Which begs the query, what’s correct stress value…$200?
However wait, there’s extra!
It attaches to any pump that matches a Presta valve, together with handheld mini pumps. The press-on chuck has a locking knob, twist it to tighten a rubber seal contained in the chuck across the Presta valve.
