What Our Gearhead(R) Experts Are Saying:"I spec this system for riders who have already optimized everything else and want to squeeze the last few watts out of a Red or Force AXS build. The 3D-printed hollow titanium pulleys are genuinely impressive up close, and the 35 to 40 percent friction reduction over stock is something you can actually feel on long climbs where every bit of drivetrain efficiency matters. If you are building a race-ready road setup, the OSPW RS 3D Ti v2 is the finishing touch that holds up."Every watt matters when the road tilts upward and the pace lifts. The CeramicSpeed OSPW RS 3D Ti v2 exists for exactly those moments - a precision-engineered pulley wheel system that pulls measurable friction out of a SRAM Red or Force AXS drivetrain and returns it to the rider as usable power. The 3D-printed hollow titanium pulleys at the heart of the system deliver a 35 to 40 percent friction reduction over the stock pulley configuration, a gain that compounds across long efforts and sustained climbs. The updated RS cage design is not just a visual refresh - the angular geometry reinforces structural strength and durability while blending cleanly into the modern aesthetic of high-end road builds. For riders who have invested in a top-tier groupset, the OSPW RS 3D Ti v2 is the component that ensures none of that investment is lost to drivetrain drag.
