Sorry guys the cranks are too weak for my weight.......the RF 180mm LP's are fine.
Now the stem/bar combo.......that's what I want with matching bar ends too.........I should have got a set when I got the forks......ah hindsight...... .....
Still a very rare bike esp in New Zealand......spoke to the old importer...he has a few sunn bmx frames at home-unused.......sorry no gear/parts.......he's trying to track down a ti frame & fork he sent to a mate to sell...... will keep you posted...
