Trying to finish off a budget DH build, and these are the parts I need: 31.6mm seatpost, saddle and 4 bolt 36T ring.
The seatpost can be pretty much any length.
The aesthetics of the saddle is more important than anything else, something skinny preffered.
The chainring must have some life left in it.
And most importantly of all, they must all be very cheap like the budgie!
