What do I do with this?!

Hi,

I have recently acquired a Motobecane Sprint. It has Nervar cranks with a mix of Hublet and Simplex gears. I would like to renovate it and have a couple of questions, namely:

1. How do I remove the cranks and BB on it?
2. How do I clean up the rust on the chromed sections such as the handlebars?
3. Is it wise to attempt to dismantle the rear dérailleur to clean it or is this a job for an expert?

Below are a couple of photos:

Any advice is appreciated.

Thanks,

    I use a ball of kitchen foil to clean up rusty chrome........sounds weird......but works.

    Great piece here about restoring chrome. Coca Cola is the key! It works! http://www.lfgss.com/thread4900.html

    • 1. Jam a coin in that slot in the cap and unscrew it using a gripper wrench or pair of pliers. Make sure it's a big enough coin, looks like the last guy to try it wasn't so careful. Then use a socket to undo whatever you find under it, and a taper crank extractor to pull the cranks off. You might want to take the BB to the shop - old ones can be a pain!
    • 2. Wire wool, but be gentle!
    • 3. Not if you're not used to dismantling mechs, go for it if you are. Dismantle, clean in white spirit, reassemble and lubricate as you go.

    Begorrah! That thing is huge... are you 6' 8" tall or something??? Mind you, the saddle looks like it is welded to the seat tube lug. Who rides these things, even in Holland? :lol:

    Have a go. Even if you mess up, replacement vintage bits are still available for it anyway. Good practice!
