hello,

so recently i found my very old Haro Shredder from the 90's while clearing my nans old shed and ive decided to rebuild it all, maybe to ride. maybe to be more of a sentimental type piece.
originally i come off this over 10 years ago and ruptured my ligament in my knee while being a teen thinking i have "sick skillz" so it never got touched after that. Ive inspected the frame and there is no cracks or rust its actually in great condition.
​​​​​​
so my question is....this thing has a gyro, for one...can i redo this without one? as i know gyros arent really a thing anymore.
also can anyone tell me what bottom bracket this would take? as i have looked online, but there is alot of choice and i am just super confused.

i dont think id rebuild it back to its original looks, as i actually hated the look of it back then - hence why its white and not the original black with the huge shredder logos.

thanks in advanced for any info

edit - because im new to this forum i cant post the picture of the bike
