I have an MBK (have painted over/ peeled off most of the decals) mixte frame with forks, full mudguards, seatpost, quill stem, handlebars, front and rear brake (no levers or cable) for sale. Can probably take all the bits off if you only want the frame...
It's 50 c-t
Pick up from SE London....looking for 60 quid or best offer.
Let me know if you have any questions.
