This is a new complete assembled from new parts and a after market 7075 aluminum axle made to help give room for disc and rotor clearance adding 5mm of length to the rotor side making the overall length 113mm. Bolts needed are 3/8 16tpi standard size. I have bolts and shimano type cogs if needed box tangent and crupi work good. The disc mount is standard 6bolt. Any question please ask.

I have black sun envy rims in 20” or 24” and carbon rims also if you want laced ready to ride. I also have axles for this conversion. If you need a wheelset i can also build. Just let me know what all you need
