so is this what happens when you get a podium finish
the standards for winning get upgraded

I think I need to finish a trophy to present to this years 2nd place finisher first
before attempting any other "requirements"

Another congratulations on last years build off .

some more parts for the build up


The 3 piece cranks are something i had in my parts bin
dont know what bike they are from but they are heavy like cast iron
Which is good for a gravity bike
and I need a 3 piece crank to either re position or remove (along with the huffy sprocket) when going downhill

I will be needing an adapter for the cranks to fit the pedals the same exerciser pedals I was given as a trophy for getting 2nd place last year
thank you Kingfish

Plus some 20" suspension triple tree forks for the front

pulled out a worksman 20" with drum
also a 20" moped rear wheel that someone before me added in a costerbrake (but this may get changed later)


The part that I really was looking for was the moon snap on caps that I once had on my old pt cruiser


I thought with the disc being 15" and the wheel from the bike measuring out to 16"
(all wheels with decimal tires are 4" smaller that the listed size so 20 x 2.125 is actually a 16" rim)
it turns out to match up quite well



I originally bought them from a guy who had lost one from his complete set so i bought them at a real cheap price
the one on the left of the photo had extra damage so I was able to pick up two more at moon headquarters in Santa Fe Springs for 1/2 off since they where considered "damaged"
Good thing its for a ratrod
I dont need anything perfect or full price


The extra disc i am using for practice modifications
as you can see the snap ring part and wheel spokes get in the way

so some modifications will be needed
