• The latest acquisition. The frame is stamped BCM which research has shown to refer to Bocama lugs. The frame may well be a '70s 5 speed budget Gitane.

    Whatever, I'm thinking rat fixie, very minimal and I'm going to need plenty of advice as to what may fit as I've been lucky enough to mess round with MTBs and a big box of miscellaneous bits over the last 15 years so I'm out of my depth here.

    I started with mtbs myself

    You got a decent steel frame there but you'll find the angles very slack and wheelbase long major clearances ahead even more if you fit 700c wheels, you might try fitting a fork with less of a rake as I did with this one . The hoops are probably 27" and look proportional to the frame I'll bet the block is a screw on, you will not get away with removing it and screwing on a fixed sprocket, there is no room for the lockring plus it screws on the same way as the sprocket major danger when braking!
    I found out the hard way!
    Good luck with your build but you'll find yourself drooling over the pics in Bike Porn and coveting some of the current projects.
