A bare-essentials SRAM kit covers both port styles and skips the rest. The Basic SRAM kit ships two M5 funnels for the older SRAM lever thread and one Edge assembly for the 2017+ Bleeding Edge caliper port, which between them reach every SRAM hydraulic brake in current and recent production. What the kit does not carry is the workshop's bleed blocks, the fluid, or the small-parts grab bag; those are the difference between the Basic kit and the Workshop SRAM, and the home mechanic with one or two SRAM bikes does not pay for them.
What's in the kit
Two 20 ml Becton & Dickinson syringes drive the bleed. Two M5 assemblies handle the older SRAM lever's M5 funnel thread; one Edge assembly handles the Bleeding Edge caliper port that 2017+ SRAM hydraulics use. Spare O-rings round out the box. The kit does not include a bleed block (sold separately, sized to the brake family) and does not include fluid (sold separately, DOT 5.1 for Code-family or Maxima Mineral for Maven).
Compatibility
The kit fits every current and recent SRAM hydraulic brake: SRAM Code (RSC, R, Ultimate, Silver, Bronze), Level, Guide, G2, Force AXS, Red AXS, plus the modern Maven family (Ultimate Expert, Ultimate, Silver, Bronze) and the Avid Elixir / Juicy legacy and the older Formula hydraulics (Oro, C1, R1, R0, K24, K18). It does not fit Formula Cura, which uses a Cura-specific port outside the Bleeding Edge fitting pattern. The fluid call splits on the brake family: Maven and DB8 take SRAM Maxima Mineral Brake Oil; the rest of the SRAM hydraulic family plus Avid and older Formula take DOT 5.1.
