SRAM Transmission XX 104 BCD Groupset

Here are some details on the new SRAM Eagle Transmission Groupsets

Transmission Rear Derailleur Full Mount

One of the key points to Transmission’s functionality is found in the rear derailleur mount design. Termed Full Mount by SRAM the rear derailleur is now mounted to the triangle in a double shear configuration which puts it in direct contact with the cassette.

This is how SRAM’s new system improved it’s self setup and tuning capacity.

Eliminating any potential variance between previous rear triangle and hanger applications (non UDH derailleur hanger systems) combined the specifics of the T-Type cassette provide a specific interface which the Transmission Derailleur is asked to function in. (not to mention the full mount derailleur provides a more robust attachment point for the derailleur and eliminates a fastener found on standard derailleur / hanger interfaces)

SRAM T-Type Compatibility

SRAM’s new Transmission, or T-Type, components are interchangeable within the Transmission ecosystem.

You’ll see some notable differences on the components such as the Flattop chain design, the Full Mount (requires UDH frame capacity) Derailleur as well as the revised 8 bolt SRAM Transmission Direct Mount chain ring design.

SRAM Transmission

SRAM AXS has evolved to SRAM Transmission – the newest 12sp Eagle lineup.

Seven groupsets are available including the XXSL as well as XX, XO with Power meter options and E- Bike specific options.

As soon as you see this new Eagle Transmission groupset you just want it on your MTB.  From the derailleur, shifter, cassette, a flattop chain (T-type), down to the crankset: it’s been re-designed.

Along with the new looks SRAM sets a higher bar for durability while raising expectations for the future of mountain bike shifting: from setup and tuning to the trails.

It’s all different but for the right reason, progression.

SRAM UDH Full Mount Derailleur

SRAM evolved the UDH system to incorporate the new 12spd Eagle Transmission derailleur’s Full Mount design for improved shifting performance.

The new Transmission (derailleur) has a beefier structure for improved durability. The UDH Full Mount design is more compact, tucked under your chainstay, better protected from rocks and objects that tend to damage components. Transmission Derailleurs are modular and SRAM offers individual replacement parts including designed skid plates in high contact areas.

Along with the revised derailleur the rest of the Transmission components were designed to withstand time and whatever the trails throw at them. They feature stronger materials and improved coatings to extend service life.

Pulley wheels are larger giving a smoother and more efficient pedal feel. The Magic Wheel protects your lower derailleur pulley and chain even if the pulley is jammed to a stop.

Other T-Type Design Improvements

The Flattop chain is 5x stronger and designed around the all-new 10-52 twelve speed cassette. The T-Type Cassette features “Shift Lane” technology. The Shift Lane design provides chain contact in two cassette lanes at the same time. The chain can now be shifted under huge amounts of power while still producing smoother shifts under power or not. Goodbye clunky shifts.

The newly designed and more durable crankset seamlessly syncs the groupset all together. This new crank arm design with an integrated chain guide puts SRAM back on the map for crank choices amongst custom bike builders within the industry.

Quick Installation, Setup & Tuning

More connectivity, more personalization.

With SRAM Transmission your bike has become even more bolt up and go, leaving your setup and adjustment worries behind. Choose your UDH compatible bike from SRAM’s database of over 600 bikes on the Sram AXS app and sync your bike to shift correctly. No more need for a B-gap tool or limiter screw set. Just ride.

 SRAM Transmission: The option is there for you.

More durable, reliable with faster and smoother shifting. As well as app integration to your personal riding experience.

Price points and models to choose from suit needs from the weekend warrior, to the upcoming pro, all the way to the top tier level MTB racer – or any rider who wants the easiest setup and adjustment available.

The new Eagle transmission was created to change the expectations and set the standard for what will be expected from the MTB industry. With SRAM Transmission mountain bike shifting is re-imagined. It’s the best shift performance you can possibly have on a mountain bike and will be for years to come.
