Getting back into BMXing and need some mechanical advice
I have a 2008 GT Vertigo, and I want to get back into riding it as I've spent the last decade riding MTB. I have a *small* issue though, I stopped riding because I needed a new rear hub and I dropped the wheel off to a bike shop, and they lost it, so I need to buy or build up a new rear wheel. I was hoping for a little advice on the best way to do it. It has a 33t sprocket iirc, but I remember that being part of why it was difficult to replace, so I know I can change the sprocket and chain for something more common, but how do I know what to buy for it?
I've modified cars before and maintained bikes, but this will be my first custom bike job and I'm feeling out of my depth. Any advice would be greatly appreciated, even if it's just pointing me in the right direction. Thank you and happy riding!
