Sram: Road racing. CX. Gravel. Coffee rides. This derailleur truly does it all and looks good doing it. The single cage length works with any cassette size from 10-28T to 10-36T, in 1x or 2x configurations. Shifts are fast and precise, and the Orbit fluid damper keeps the chain in control, whether the obstacle you’re hitting is a pothole or a root. And the graphics pop just the right amount, to remind you that you have the coolest fully wireless drivetrain out there.FEATURESOrbit chain management technology keeps the drivetrain quiet and secureCompatible with both 1x and 2x drivetrainsSRAM AXS enabled, allowing easy personalization36T-max derailleur is compatible with cassettes with big cogs from 28T to 36T SPECIFICATIONSSpeed (RD): 12sCable pull ratio: n/aCage (RD): n/aMax tooth: 36Color (RD): IridescentPulley bearings material: SteelCage material (RD): Aluminum
