Just think how much of your pedaling effort gets wasted by derailleur pulleys on a typical bike ride. All that weight. All that friction. Sapping your energy, and as a result, your speed. I know I think about it all the time, and I find myself wishing someone could come up with a solution -- at any cost.
Well, that solution is finally here.
CeramicSpeed, a Danish company which is known for their high-quality ceramic bearings for bicycles has just introduced the latest must-have weapon for racers and triathletes -- hollow titanium ceramic bearing derailleur pulleys. Made in cooperation with the Danish Technological Institute, these 3D printed pulley wheels are the result of 4 years worth of R&D, and are said to last 3x longer than their standard aluminium pulleys, while weighing 10% less! And with their cutting-edge ceramic bearings, just think about how much speed a person could gain by switching to these. I get excited just thinking about it.
"Big dreams belong to the ones who dare," says the company's press release, "and the team of professionals at CeramicSpeed dared to shatter the way expert gear for high-end bicycles are made." I know these are like a dream come true for me. I'll never look at derailleur pulleys the same way again.
According to CeramicSpeed, the 3D printing process, also known as "additive manufacturing" builds up thin sequences of titanium dust, heated by laser light and "imprinted in layers of perfection." But that is only the beginning, as the pulleys then go through a series of "after-treatment processes to highlight a design and finish studied into detail by the most creative minds."
But a secret weapon like these pulleys isn't for everyone. Nope - the company says its first production run of these exclusive speed enhancers is limited to only 10 marked sets, individually numbered, and each one delivered in an exclusive case. And the price of admission is only $1000.
Some people might scoff at $1000 derailleur pulleys, but they just don't get it. Speed doesn't come free, and the kind of performance gains these things would just have to deliver is worth every penny.
