UH1-105 is a direct replacement to the stock hub that comes with all three models of the Simucube 2 family of direct drive base systems,
It adds 105mm extra length to the stock hub and with smaller diameter is the perfect add-on in order to extend the motor shaft and give enough room and clearense for you center monitor in order to be as low as possible and to bring it closer to the servo axle.
Total lenght 155mm from the front face of the servo.
At the same time it is compatible both with the stock Simucube 2 quick release and also with any 70 PCD quick release on the market,
Both the stock QR and the 70 PCD holes are threaded M5 so no need for ugly nuts.
The UH1-105 is also compatible with out ProXT modular extensions for those that need more than 105mm extra length.
See this great video from Greg at GTGreg on how to install the UH1-105.
If you are having problems unlocking the drive lock that holds the shaft use one of the 4 M6 bolts in one of the 2 threaded holes circled in red in the picture below, once it bottoms out half an extra turn clockwise will unlock it. We suggest to leave a 5mm gap from the servo frame when installing the UH1 to avoid rubbing.

Perfect 155mm 105 extension. The photos don't do the Blue justice. easy to swap with standard size Torque key. Craftmanship is second to none same as support. Thank you will be back
This is the second UH1 extension I’ve bought from SimCore. First was the UH1-75 in black. It was a fantastic extension. I then decided I wanted a longer extension and when I saw George was now producing them in gold I immediately bought the UH1-105 in gold…as I already have a UM1- ALN in gold. The extension is absolutely beautiful. The install is easy and quick. It replaces the SC2 stock shaft which really makes it a clean setup. Shipping to the West Coast of the USA was fast. This thing just screams quality. Hopefully someday we see some SimCore button boxes and more accessories. In gold of course:) Thanks again George.
I had been waiting a while to put in an order for one of the SC2 extensions George produces. Finally I stopped procrastinating and ordered one, installed it, and wow am I happy. I managed to reduce the number of components in my extension configuration from 3, down to 1, AND as an extra bonus, the machining on this piece is absolutely perfect, so there is no visible movement in any part of the shaft itself like my previous setup. This is the component you want/need if you want to put a custom QR on your rig, AND you want to extend the default shaft length. A really fantastic product, well done mate.
