Hello,
This is me, and whilst I appreciate your opinion, they are a little more than that - have you seen the cost of stainless steel bar? They are all machined down shells to fit both the stainless bottom and the top cap, the stainless bottom is machined, chamfered and polished too, this isn't 5 minutes work, and the 'proper' engineer that makes them is used to the tolerances and standards that keep planes in the sky so isn't skimping on expertise. Yes, I could sell them for less, that would also mean that there would be no point though, I am not making a lot of money doing this and genuinely try to keep my prices as low as I can.
Yeah, sort of, coffee and cycling go hand in hand historically, maybe they are a bit Hipster, and cynical and too expensive, but I tried to offer something interesting for the people who like both vintage bikes and coffee, maybe its not a good fit here
