Quick answer
The Axle 9 #60485 is a 9-module-long axle designed for Circuit Cubes builds, offering a precise fit for medium-span wheel and gear setups. It is a single replacement part that works with standard Circuit Cubes hubs and connectors.
Why axle length matters in Circuit Cubes
Axle length determines how far apart your wheels or gears can be placed on a build. A too-short axle limits spacing; a too-long axle may wobble or require extra supports. The Axle 9 #60485 hits a sweet spot for many common chassis and drivetrain designs.
Circuit Cubes axles are measured in module units, where each module corresponds to the spacing of standard building bricks. The '9' in Axle 9 indicates it spans 9 modules, which is roughly 72 mm (or about 2.8 inches) – enough for a typical 4-wheel vehicle base.
Trade-offs to consider
If your build requires a shorter axle (e.g., for a compact robot or single-axle cart), the Axle 9 may be unnecessarily long and could protrude. For longer spans (like a 6-wheel truck), you might need a longer axle or multiple axles joined with connectors.
The Axle 9 is sold as a single piece, so for multi-axle builds you will need to purchase multiple units. It is not compatible with non-Circuit Cubes hubs or wheels that use different shaft diameters.
Decision rules for using Axle 9 #60485
- Measure your build's wheelbase: Count the number of brick modules between your intended wheel hubs. If the span is 9 modules, the Axle 9 is the exact fit. For shorter spans, consider a shorter axle or use spacers. Always measure first to avoid an axle that is too long.
- Check hub compatibility: The Axle 9 works with standard Circuit Cubes hubs and wheels. It will not fit hubs designed for larger or smaller shaft diameters (e.g., some third-party building systems).
- Plan for multi-axle builds: Since each Axle 9 is a single piece, a 4-wheel vehicle needs two axles. For a 6-wheel design, you will need three. Order accordingly to avoid delays. Buy in multiples if your build requires more than one axle.
Product facts
-
Axle 9 - #60485: The Axle 9 #60485 is a single replacement part from Circuit Cubes, identified by SKU 60485, and sold as one axle. This means you can replace a lost or broken axle in your existing build, but you will need to buy separate axles for each wheel pair.

Is this axle right for you?
Best for
- Replacing a lost or broken axle in a 9-module span build
- Building a standard 4-wheel vehicle with a 9-module wheelbase
Not for
- Builds requiring a wheelbase shorter than 9 modules (consider a shorter axle)
- Non-Circuit Cubes systems with different axle diameters
