Rivendell Bicycle Works Silver2 Shifter

No, the Silver2 shifters are designed specifically for drivetrains up to 9 speeds. They will not provide the correct cable pull ratios for modern 10, 11, or 12-speed systems.

These shifters are not compatible with SRAM rear derailleurs. They are designed to work with most other standard rear derailleur brands, provided you are running a 9-speed setup or lower.

The light ratchet mechanism provides just enough resistance to hold the derailleur in place while still allowing you to feel the cable tension. It prevents the lever from slipping under vibration while maintaining the smooth, intuitive feel of a traditional friction shifter.

Yes, the hinged bar-clamp design is versatile enough to be mounted as a thumb shifter on flat bars or as a bar-end shifter on drop bars. The adjustable cable exit barrel helps you route the housing cleanly regardless of your handlebar choice.

Because these are friction shifters, there is no indexing. You shift by feel, listening for the chain to seat properly on the cog and adjusting the lever slightly if you hear any noise. It requires a bit of practice, but it eliminates the need for constant derailleur hanger adjustments.
