About The SRAM GX Eagle T-Type AXS 12-Speed 52t Max UDH Black Rear Derailleur
The SRAM GX Eagle T-Type AXS is a wireless Eagle Transmission rear derailleur that mounts directly to UDH frames with no hanger. It works with T-Type 12-speed cassettes up to 52t and pairs through the standard AXS procedure.
SRAM calls it its most repairable derailleur: skid plates and the two-piece outer link are replaceable, and the cage and clutch assembly come off without tools. A steel inner cage adds durability. The battery is not included.
Who It's For
- Mountain riders with a UDH frame moving to a wireless T-Type drivetrain.
- Riders who crash or rock-strike derailleurs often and want replaceable parts.
- Consider a different derailleur if your frame lacks a UDH interface or you want mechanical shifting.
What to Look For
- Frame: Requires a frame with a UDH interface.
- Battery: Not included; uses an SRAM AXS battery.
- Drivetrain: T-Type chain and cassette, 12-speed, 52t maximum.
Key Features
Hangerless Full Mount interface. Mounts around the axle and contacts the cassette directly, gripping both sides of the frame for a stronger connection.
Revised battery position and gearbox. Reconfigured to better protect the derailleur from impacts.
Tool-free cage and clutch. The cage and clutch assembly can be removed and upgraded.
No adjustment. Setup follows the standard AXS pairing with no limit screws to set.
Rider Intent Summary
- Biggest strengths: Wireless Transmission strength and repairability at the GX tier.
- Tradeoffs: UDH frame and AXS battery required.
- What makes it different: The most repairable derailleur SRAM has made, per SRAM.
Victory's Take
We think GX T-Type is where Transmission makes the most sense for everyday trail riders. Victory Bicycle Studio can confirm your frame's UDH and set it up in the shop.

Frequently Asked Questions
Do you offer free shipping?
We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.
How much does shipping cost?
For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
