I have both and I gotta say do the wheels first. They are generally more expensive and you have the cash so pull the trigger.
As far as apes go, really consider going taller on the apes, 14 or maybe 16. I've had my 12.5s for 2 years and love them, but I have a set of 16s about to go on. So make sure if you only want to do it once.
well I got some prices today from my buddy who had a shop.12.5 apes ,risers,all braided lines installed around 600.00 wild 1's.
dna spokes 16" with new polished rotors no pulley 1,200 installed I think I am gonna go with the rims because all and all I am totally comfortable with my bars.
