Ah, the classic "all pumps are created equal" assumption. How quaint. Let's ignore the fact that a pump's build quality, accuracy, and compatibility with certain valves can significantly impact its performance.
Of course, if we're strictly playing the price-to-value game, then sure, a no-name brand pump might be sufficient for your casual commute. After all, who needs precision or durability when you're only pumping up tires once a week?
But for those of us who appreciate the finer things in life, like a perfectly calibrated pump and a smooth piston stroke, the idea of settling for a budget option is laughable. Sure, a high-end pump might cost an arm and a leg, but can you really put a price on the satisfaction of knowing you're using the best?
And let's not forget about the poor, neglected professional roadies. You think they want to be lugging around a bulky, expensive pump on their already heavy-laden bikes? Please. They need something lightweight, portable, and reliable – and they're willing to pay for it.
So, to answer your question, I suppose it all depends on what kind of cyclist you are. If you're the type who's content with mediocrity, then by all means, go for the cheap pump. But if you're someone who values quality and performance, then do yourself a favor and invest in a pump that will last.
