The parts are close to new. I wiped the dust off for the pics. A detailed cleaning and this bike would would look like new. Wheels are Mavic 222X rims with an XT rear hub and DT spokes. Front wheel has a sealed bearing disc compatible that can't determine the brand.
I'm thinking its a White Industries but I may be wrong. Rockshox Indy C long travel front fork.
