- Specs
- Available in black anodized and raw (unpolished) silver
- 28 teeth to 52 teeth in 2 tooth increments
- Boost and non-Boost versions
- Standard/non-boost rings have a 3mm offset (inward)
- Boost rings are flat (so 3mm outward of our standard/non-boost rings)
- Standard/non-Boost rings can be flipped so the offset shifts outward to give you 3mm more outward offset than our Boost rings
- This set up is is used on M30 cranks for a 55mm chainline needed for SRAM Transmission, Rohloff hubs, and Super Boost 157mm spaced hubs
