FAQ

Good questions

Get to know SRAM

There's more to SRAM than this one product. Our SRAM page has the full SRAM lineup we carry and more about the brand.

What is the Full Mount Hangerless Interface and does my frame need it?

The T-Type derailleur mounts around the wheel axle itself with SRAM's Hangerless Interface and Full Mount attachment, so there is no hanger to bend or break. SRAM states that Eagle Transmission requires a frame that is Universal Derailleur Hanger (UDH) compatible.

Is the XX SL T-Type group approved for E-MTB use?

No. SRAM lists the XS-1299 cassette and the XX SL T-Type chain as not compatible with E-Bike use, and the chain page says it is not suitable for E-MTB.

How does the integrated power meter work and what is it compatible with?

The spider-based dual-sided power meter measures power directly at the crankset. It is compatible with Flight Attendant and sends data over ANT+ and Bluetooth low energy.
