SRAM XX SL Eagle Transmission MTB Group | 55mm Chainline, 174mm Q-Factor –

If you’re chasing podiums, KOMs, or just want the lightest, sharpest shifting setup out there, the SRAM XX SL Eagle Transmission is the groupset we’d put on our own dream build. This is SRAM’s flagship for cross-country performance—think world cup tech, dialled for everyday trail heroes.

Why We’re Excited About It at Bike Clinique:
We’ve fitted the XX SL Eagle Transmission for riders who want every watt to count and every gram to disappear.

How Does It Ride?
Fast. Light. Effortless. Our customers have been blown away by the instant, wireless shifting and the way this setup just disappears under you—leaving nothing but pure speed and control. The XX SL is perfect for riders who want no compromises, whether you’re racing or just want the best of the best on your local loop.

Is It Right for Your Bike?
This is a truly high-end setup, and it’s not compatible with older Eagle drivetrains or e-bikes. Your frame needs a UDH interface for the direct-mount rear mech.
