Used Shimano ,worked fine on 79 Robinson     Haven't gotten dust caps yet .Picked up Cranks chain ring and bolts in a trade

Picked it up ,stripped it down and yes 1979 Robinson has Euro B.B. Scott Clark signature edition square tapered spindle from Shimano ,was new too tinkering around  with this configuration .Nice thing is just about any old crank arms that are square  work ,I traded for cheaper Shimano arms and friend came up with the bolts which are specifically made to bolt on crank arms. Easy peasy, just now I need to pick up some dust caps .Not necessary but completes the look  .With all the colors black,chrome ,red ect  give it a little pop color wise .    Getting B.B. screwed in perfectly from each side was only tricky part I encountered .Not much surface to get crescent wrench on to thread,so to keep things stable wrapped frame in cloth and put in vice so I could get some torque .  Used Phil wood grease ,tighten each side till spindle stops side to side movement. Tighten too much it presses on spindle ..it wont  turn at all, find that perfect medium between too much or too little. Hope this helps.

Just need to find arms       bolts     chain-ring   /   chain-ring bolts  and your good to go if you already posses B.B.   Ones I picked up were like 70.oo. Most like  70-130 $ range  .Redline if your thinking 400 Sugino cranks 600.00 up?  Spend y .Keep your eye open on bmx museum for sale section .Crank sets come up  every day . Keep trade options open  I have traded for both sugino cranks ,recently traded Ukia rim set for  NOS Red anodized Sugino 600,with new in the box SR pedals.

Shoot American B.B. easy  ,like bailing from your bike. another can of worms Euro B.B.
