I just bought a cheap near mint PureFix fixed gear bike. I'm going to eventually upgrade some of the components before I possibly splurge on a high end bike if I enjoy this. I am looking to upgrade the wheelset, crankset and bottom bracket.

I was wondering if anyone was familiar with some of the components I'm researching. Weight isn't a priority so much as reliability and durability. I'll primarily be using the bike to ride around town to get accustomed to fixed gear riding and to get me out of the house with the intent of improving my cardio and my basic riding skills. I live in Florida so the area is very flat, I was thinking maybe a 48/17 gear ratio.

For the wheelset I came across a pair of Aeromax Pro HD wheels on Amazon. OK price , decent reviews, seem sturdy enough. I'm not into the deep dish wheels, more of something I can used a medium tire on for small town riding and decent pavement protection.

For a crankset I found the FSA Metropolis set that looks solid but it doesn't come with a chainring. Any suggestions on a sturdy chain ring? I'm about 5'6" and 180 lbs, I just want something strong that won't warp or fail if I put in a little effort peddling.

I've yet to decide on a bottom bracket, but I prefer sealed.

Any advice, suggestions or feedback would be greatly appreciated or if you have other recommendations for components I'm open to suggestions.
