CerámicaVelocidad

The fastest drivetrain is the one that loses the least energy to friction — and CeramicSpeed has built its entire brand around that principle since the Danish company's ceramic bearings first rolled at the Tour de France in 2001. Today, 305 products cover every contact point where energy escapes: OSPW oversized pulley wheel systems that add measurable efficiency to Shimano, SRAM, and Campagnolo drivetrains; hand-assembled silicon nitride ceramic bottom brackets and wheel bearings that CeramicSpeed claims are 58% lighter and 30-50% faster than steel; and the UFO product line of chain prep, lubricants, and cleaning products for riders who want the complete friction-reduction stack. The collection spans from UFO maintenance essentials up to the flagship OSPW RS 3D Titanium 20th Anniversary systems — a range that covers the rider optimizing one contact point and the one replacing every bearing on the bike.

About CeramicSpeed

CeramicSpeed was founded in 2004 in Holstebro, Denmark, by Jacob Csizmadia — a former competitive inline skater who discovered the performance advantages of ceramic bearings while chasing a 24-hour distance record. The technology transferred directly to cycling: silicon nitride ceramic balls, manufactured using processes originally developed for NASA applications, are 58% lighter and 30-50% faster than conventional steel bearings according to CeramicSpeed's testing. Every bearing is still hand-assembled at the Holstebro facility, where producing each ball takes 50 to 70 days. In 2016, CeramicSpeed acquired Friction Facts — an independent Colorado-based testing lab — to deepen the technical rigor behind their efficiency claims. Learn more at CeramicSpeed's official website.

The 305 products at RA Cycles cover three categories. The OSPW (Oversized Pulley Wheel System) lineup — the brand's most recognized technology — is available across Shimano 9250/8150, SRAM Red/Force AXS, and Campagnolo compatibility, with standard, 3D Titanium, and limited 20th Anniversary editions. Bottom brackets span every major standard: BB30, BB86, BB65, DUB, and threaded options. The UFO product line extends the friction-reduction philosophy to chain prep and maintenance: wax formulations, drip lubricants for indoor, wet, and all conditions, cleaning products, and bearing service kits.

For complementary drivetrain upgrades, explore bottom brackets, cranksets and chainrings, and the CeramicSpeed Alpha collection at RA Cycles.

R&A Cycles - 50th Anniversary

50 YEARS AND COUNTING

From a Brooklyn storefront to flagships in Walnut Creek and Miami, from handwritten mail orders to a fully digital custom bike builder — RA Cycles has spent half a century doing one thing: serving riders who demand the best. That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
