Can anyone advise what the difference is with these three hubs? They appear basically identical apart from the holes on the non-brake side.

3 holes, similar to my current hub, drive side facing away.


6 holes


6 holes, Elongated spoke holes

I've just looked at my G3L and it has six bolts holding the drum/sprocket on with a unused hole between each bolt (12 holes in all). On the offside there are only three large hole thus you have to spanner the bolts tight ( there's lock nuts on the other side) as you can't use a socket/ box spanner on three of them.
I've no idea of this "correct" but that's how it is on my bike.

That is how my hub is a well.

The other two are similar, unfortunately of the 3 for sale the one that matches yours is the least best condition.
