Front Thru Axle to Track Rear Hub Adapter

The 100x15mm hub standard for front wheels is dead. There are tons of very cheap high end 100x15mm hubs that could be repurposed for use as track rear hubs. The chain line of the 6 bolt ISO or Boyd Centerlock cog is about 41.5mm, only .5mm off the standard 41mm Chainline. I would love to see someone make this, sell it, whatever I dont care.  Please attribute if you do something with it.

I have an alternate version for the more common 12mm hub as well, contact if interested.

This design requires two 4mm knurled axle nuts to meet the 120mm hub width.
