OK so the rims are Alex dx 32 rims both F and R.
32mm wide, 36H black. They also sell a 32h version but I chose the 36 to have more spokes.
No modifications to fit 2.5" tires.
Spokes are 13/14g butted. Nipples are alloy 12mm. Rear hub is a 3 speed SRAM imotion disc version and front is a shimano xt with disc.
I hope this helps. I bought everything online and I think each rim was approx 34$.
