Marin Team One mountain bike frame in Medium to fit 29 wheels. I bought this bike 2 years and rode it around once a month and I have recently changed frame so this one is for sale now. Flat mount brake caliper mounting points (I have a flat mount rear caliper for sale – if you would like it then I can add it for free). I have left the rear brake hose and dropper post hose in the frame to make life easier for the new owner.
