GSI AH50 Hub Extension

The GSI AH50 hub extension is the perfect add on to your GSI wheel.
It extends the shaft by 50mm.
Three 5mm non-threaded holes and three M5 threaded holes for 70 and 50.8 Pitch Circle Diameter on both sides gives you the most flexibility and strength.
Each side uses a 70mm bolt pitch pattern (connects on the wheel side, not compatible for direct mounting on the Simucube base side)
