- Ratio Technology's 2026 Drop Bar Conversion Kit has been released, allowing SRAM Eagle 70/90 T-Type derailleurs to function with SRAM Apex 12-speed mechanical shifters.
- The kit is priced from $76.34 USD and is available for purchase.
- SRAM's Eagle 70/90 T-Type derailleurs were previously incompatible with drop-bar shifters due to different cable pull ratios.
- To address this, Ratio Technology developed a CNC aluminum fin and replacement link to adjust the cable pull ratio and add a barrel adjuster.
Ratio Technology's 2026 Drop Bar Conversion Kit allows SRAM Eagle 70/90 derailleurs to work seamlessly with SRAM Apex 12-speed mechanical shifters, providing a solution for cyclists seeking wide-range mechanical shifting on drop-bar bikes.12
The kit features a CNC aluminum fin that adjusts the cable pull ratio, making it compatible with Apex shifters, and includes a replacement link and cable adjuster for on-the-fly adjustments. This modular design enhances the shifting experience, especially for gravel biking, where reliability under load is crucial.5
According to Ratio, the system supports a 10-52T cassette, offering a wider range than SRAM's 1x road cassettes, and is more affordable compared to T-Type wireless groups. The kit is priced starting at $76.34 and is crafted from 6082 aluminum for durability.

However, it is important to note that the kit is not compatible with SRAM's 10- or 11-speed drop bar shifters, even with upgrades. This innovative solution is set to enhance the performance of drop-bar bikes significantly, making it a valuable addition for cycling enthusiasts.
Overall, Ratio's conversion kit represents a significant advancement in making SRAM's previously incompatible systems usable on drop-bar bikes, ensuring cyclists can enjoy the benefits of modern drivetrain technology without switching to electric systems.
