Alot of it interchanges amongst BMX bikes, but you need to know what your working with. Figure out what you have on the bike currently so you can cross reference diameters, heights, bearings, etcAre parts universal? For instance the cranks and seat post
Figure out your bottom bracket size so you can get the right bearings....1 piece, 3 piece, whatever..Are parts universal? For instance the cranks and seat post
Its a mid 90s bike for sure. Frame looks pretty good, but the bars and forks are rusty. I'll probably do a custom build, rather than restore it.What year Robinson? Pics? If it’s vintage 80’s / 90’s it’ll most likey have an American bottom bracket (the bigger one). Euro BB is the smaller one and what most post 2000’s bike companies use now even on new production retro bikes (SE’s line etc.).
For parts I always enjoy hunting on eBay and Craigslist. The online stores mentioned here are good. I’ve used dans comp and planet BMX before too. For the stuff you find on eBay those type sites are good to confirm the price is good. Sometimes you can find a full bike on CL that has two of the parts you’re looking for, say handle bars and cranks, for the price you were ready to pay for just cranks. Then you can sell off the other stuff. eBay has a lot of NOS (new old stock), used and new stuff. I’ve built up 80’s bikes with 80’s parts I’ve hunted down and I’ve built up 80’s and 90’s bikes with a mix of old and new parts. Just depends on what you prefer but the hunt is half the fun for me.
Post some pics. I had a 91ish 20” Robinson for a little bit. Fun bike.
I don’t think they sell parents at a bike shop LOLI just pulled my old Robinson bmx bike out of my parent's backyard and I want to rebuild it. What's a good place to buy parents. Looking for bars, 3 piece cranks, seat, seat post, etc...

I'll post some pics tomorrow. Thanks for the reply
Bad ass...always wanted one of those....or a tandem. Found out recently the cruiser I have is a 1980....lol. got it for $60.
My son took that same bike (Robinson 4140 Chrome Moley Steel) last year and took it all apart and put all the parts including the frame in a big plastic bin (he got from Wallmart) and just let it soak in Vinegar for a couple of days. After a couple of days he was able to just wipe everything off including the rust.Its a mid 90s bike for sure. Frame looks pretty good, but the bars and forks are rusty.
