Ratio, the makers who hacked 11 to 12-speed SRAM road to MTB with its conversion kit, just announced a SRAM Transmission replacement cage. The SR52T cage is a replacement for your SRAM Transmission cage–the cross-braced structure is designed for stiffness, the form and chamfering help it deflect away from any obstacles, and at 90g for the cage, it will reduce the weight of your SRAM GX* Transmission derailleur to less than all but the SRAM XXSL* model.

Available with or without pulley wheels at Ratio.
