OSPW RS 3D Ti v2

What Our Gearhead® Experts Are Saying:

"The OSPW RS 3D Ti v2 is what I recommend when a rider has a Red AXS or Force AXS build and wants measurable gains without touching the rest of the drivetrain. The 3D-printed hollow titanium construction is genuinely impressive from an engineering standpoint, and the 35 to 40 percent friction reduction over stock is not marketing language — it shows up in the data. The updated RS cage geometry also addresses durability concerns from earlier iterations, so this is a system built to perform across a full season of racing and training."

There is a category of upgrade that does not require a new groupset, new wheels, or new geometry — it requires looking more carefully at what is already there. The CeramicSpeed OSPW RS 3D Ti v2 sits in that category, targeting the pulley wheels in a SRAM Red AXS D1/E1 or Force AXS D1 drivetrain and extracting the efficiency losses hidden inside the stock configuration.

At the center of the system are 3D-printed hollow titanium oversized pulley wheels built to CeramicSpeed's exacting tolerances. The hollow construction keeps weight to a minimum — 87g total for the complete system — while the material itself offers a strength-to-weight ratio that aluminum cannot match at this scale. The result is a pulley that resists deformation under load while rotating with substantially less friction than the OEM alternative. Measured against the stock pulley configuration, the OSPW RS 3D Ti v2 delivers a 35 to 40 percent reduction in drivetrain friction, a figure that translates directly to saved watts across the full range of efforts from threshold climbs to sprint finishes.

The RS cage is not the same unit found on earlier OSPW generations. CeramicSpeed redesigned the geometry for the v2, reinforcing the angular structure to improve strength and durability while bringing the visual profile in line with the contemporary aesthetic of top-tier road builds. The cage retains stable chain retention without introducing drag, and the system integrates cleanly with the derailleur body without requiring proprietary tools or specialized installation knowledge beyond standard derailleur service.

For riders already running one of the supported groupsets and looking for the final, measurable optimization in a race build, this system delivers verifiable efficiency gains in a package that weighs less than most alternatives and outlasts them.
