Last day I received my order from VeloSolo.
A brand new converted Shimano XT M756 Front hub with disc brake mount and a 19t bolt on cog.
The Shimano TX hub is coming from VTT equipments and it look very strong and will probably roll for kilometers.

The hub has been converted by the VeloSolo guys to be used has a rear fixed gear hub with a new axle, spacers and track nuts. Every part has been re-lubed and assembled to fit in the 120mm spacing of a track frame and centered for a 46mm chainline

The cog is machined from EN36 cro-moly steel and fit perfectly on the disk mount with the 6 included bolts.
