About 2 and a 1/2 years ago I purchased a felt IA in size 58 and took it to get a guru bike fitting at a triathalon specific store locally. Long story short, my wife became pregnant and ended up selling most of my expensive triathlon equipment to make room financially and otherwise for the new addition to the family. I am now looking to get back into triathlon and am trying to figure out what size tri bike I could purchase given the fit from 2 plus years ago.
It's attached.

I don't necessarily want to drop several thousand on a bike so a used bike is of interest for me for now. Trying to see what size Quintana roo or cervelo to buy.


Any help is much appreciated.
