CeramicSpeed debuts £660 derailleur pulleys at NAHBS
3D-printed titanium with novel hollow cross-section
Published:
Just when you thought boutique bicycle components couldn’t get any pricier, Danish company CeramicSpeed has gone and utterly shattered the glass ceiling with a pair of outrageously expensive titanium derailleur pulleys developed in collaboration with the Danish Technological Institute. The price tag is a whopping US$1,000 (£660) – but hey, at least you get two.
CeramicSpeed builds the pulleys using a 3D printer, which allows for a hollow structure that otherwise wouldn’t be possible with conventional manufacturing techniques. In addition to supposedly being lighter than CeramicSpeed’s standard aluminium or titanium pulleys – saving a whopping 2g or so – the company also claimed a three-fold increase in durability. Naturally, the wheels spin on CeramicSpeed coated ceramic bearings.

That said, CeramicSpeed fully acknowledges that its new 3D-printed hollow titanium pulleys aren’t exactly going to be a high volume item. In fact, the company is only making ten pairs for now, with each pulley having an individual serial number and the set presented in a needlessly fancy case.
CeramicSpeed says that it has learned quite a bit from the exercise, however, and the company plans to apply those lessons to future projects. In the meantime, 10 well-heeled customers are going to end up with some very, very exclusive (and shiny) derailleur pulleys. Don’t expect a review of them here any time soon.

Every pulley features its own serial numbers
