Tire & Wheel Adapter for Cross RC HC4 & HC6

thingiverse

These components are designed specifically for swapping out the stock wheels of the Cross RC HC4 and HC6 with more widely recognized brands of tires. While the stock wheels themselves have a good quality build, they do come up slightly short in terms of size. To make this upgrade work seamlessly, you'll need to get your hands on some new 2.5x18mm screws. First, print out two rim rings - one for each side of the tire. These will essentially broaden the lip of the metal dish rims and fit right into place with ease. Next up, print a single wheel hub. This part slides onto the inner metal ring that's nestled snugly inside the tire. By doing so, it helps distribute the pressure from the rim rings evenly across the wheels, ensuring a rock-solid grip on the tire as it should be.
