The 6x70 to SCI wheel adapters are your solution for attaching a 3 hole SCI wheel onto a 6x70 Quick release (such as Moza and many other Direct Drive Bases) They will attach to any platform with a 6x70 bolt pattern though. They are machined in house from solid aluminum. M6 bolts hold the SCI wheel onto the adapter for a strong hold. All needed hardware is included. WHEEL IS NOT INCLUDED. This is the adapter only. The adapter is 3/4" thick and weights roughly 9 ounces.
