CeramicSpeed OSPW RS 3D Ti v2 Oil Slick PVD Oil Slick, SRAM Red D1/E1, Force D1

"What Our Gearhead® Experts Are Saying:""I spec the Oil Slick PVD for riders who want the full OSPW RS performance package and something that actually catches the eye on a top-tier build. The rainbow finish from the PVD process is unlike anything else on the market, and because it's an alumina oxide coating on hollow titanium, it adds visual impact without adding weight or compromising the 35 to 40 percent friction reduction you are getting over stock. Worth knowing that the color shifts slightly piece to piece, which honestly makes each one feel more like a collector's component than a production part.""Some components earn attention on the road. The CeramicSpeed OSPW RS 3D Ti v2 Oil Slick PVD earns it at the trailside café, in the parking lot, and anywhere the sun catches the drivetrain at the right angle. The rainbow finish is not paint — it is an alumina oxide coating applied through a physical vapor deposition process, the same finishing technology used in precision manufacturing, now living on the pulley wheels of a road bike. Beneath the finish is the same 3D-printed hollow titanium construction that defines the OSPW RS platform, delivering a 35 to 40 percent reduction in drivetrain friction over the stock pulley configuration on a SRAM Red AXS D1/E1 or Force AXS D1 groupset. The reinforced RS cage geometry adds structural durability while keeping chain retention stable and drag-free. Because the PVD process produces natural color variation from piece to piece, no two systems will look exactly alike — a detail that suits a component built at this level."
