CeramicSpeed debuts £660 derailleur pulleys at NAHBS

3D-printed titanium with novel hollow cross-section

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.

James started as a roadie in 1990 with his high school team but switched to dirt in 1994 and has enjoyed both ever since. Anything that comes through his hands is bound to be taken apart, and those hands still sometimes smell like fork oil even though he retired from shop life in 2007. He prefers manual over automatic, fizzy over still, and the right way over the easy way.
  • Discipline: Mountain, road, cyclocross
  • Preferred Terrain: Up in the Colorado high-country where the singletrack is still single, the dirt is still brown, and the aspens are in full bloom. Also, those perfect stretches of pavement where the road snakes across the mountainside like an artist's paintbrush.
  • Beer of Choice: Mexican Coke
  • Location: Boulder, Colorado, USA
