Surly Monkey Nuts V1 Dropout Spacers

These spacers act as a physical stop within your frame's dropouts. They help you position your rear wheel consistently, which is essential for maintaining proper chain tension and ensuring your tire doesn't rub against the frame.

No, the V1 Monkey Nuts are specifically engineered for Surly Karate Monkey frames. They are designed to fit the specific dropout geometry of that model, so they may not work correctly on other Surly bikes.

One pack is sufficient for a single bike. Each pack contains two spacers, which is exactly what you need to set up one rear wheel.

Yes, they are particularly useful for single-speed or internally geared hub setups. By locking the wheel position, they prevent the axle from slipping forward under chain tension, which keeps your drivetrain running smoothly.

While they do push the wheel back slightly in the dropout, their primary purpose is to provide a consistent, secure stop for your axle. They aren't intended as a tool for fine-tuning chainstay length for handling adjustments.
