Description
(SuperFlux or HyperCore) with Big Tire (11.5"/12") to XR rail carrier blocks modified to match the style of OG XR PubHubs.
Thanks to @viperbite for help with getting the cover M2 bolts placed nicely.
The primary features:
A clamp - aims to reduce strain on the center axle bolts by applying a clamping force around the axle in addition to the bolts.
Fixed lowered positions - Lowered to a fixed position for a standard ride height on big tires, allowing standard battery harness routing and no fuss
Fins all around the axle block for cooling (and it just looks good imo)
Easily removable harness cover
And when it comes to the stock SF axle blocks, these ones improve against those by:
Reducing strain on the motor cable (not cutting it on sharp edges...)
Increasing space for the harnesses
Adding a more complete cable cover
Send to your CNC shop of choice for a pair of these
Make sure you have all of the body, clamp, and cover (same file for both sizes).
Be sure to include threads! Technical drawings are in the files for:
Imperial (5/16 rail bolt, standard for XR) OR
Metric (M8 rail bolt)
