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$.
