I’m after a full suss frame for my lad. 650b, 12 x 142 non boost, 140ish travel and small or possibly medium in size (he’s 5ft 6 or thereabouts, but only 13 so will grow obviously). Colour etc not too important, decent condition preferred. Budget is £400 tops. What’s in your sheds singletrack :⁠-⁠)
