|Beer can light Aluminium cranks or boat anchor heavy steel one piece crank? I think the choice is pretty obvious!|
Step one in the build is to convert this once single speed bike to a multi-speed set-up. The first thing I wanted to do was to change the one piece crank to a 3 piece crank using a conversion kit. I got the kit from Pork Chop BMX some time ago for another project that never saw the light of day. The idea is to have a better selection of cranks and to shave off some weight.

|Clean up must also involve the bottom bracket shell, loose dirt will get in the bearings. Here it also reveals the original mid 70's purple color of the bike.|
|Cup and bearings packed with fresh grease. Don't forget to add a dab on the bearing cones as well on the axle. More is always better than not enough.|
|Check for clearance between the crank arm and frame. Also, check your picture for proper focus before publishing! Aaaaaaargh :X Notice also that tire clearance is not an issue.|
|Small discrepancy here!|
|Do not ever do this, ever!|
|This is how it sits for now.|
