Ive begun stripping all the bits and pieces of my single speed candidate prior to sandblasting and powdercoating. There's a few bits that I'm not sure what to do with.
The first one is where the down tube shifters were. I've taken the shifters off but am left with the two bosses with an axle-ey thing sticking out (see below). Is the axle-ey thing meant to come out or is it there to stay?


Any tips on what to do with the shifter bosses once its converted to SS? Put the shifters back on maybe? I've seen some covers on eBay but with postage and all they end up being pretty pricey:

Also there is ring thingy on the fork - does this come off?

and another on the head tube.

Is there a nice safe way of getting them off without damaging them? I dont want to try and force these things off if they're not meant to come off!
