I'm around 190cm. I should have got a size 61, but got a 58 instead as it was on clearance and $700 off. I also prefer a more upright riding position as I do long-distance endurance riding, usually between 100-162km a ride, hence the extender.
I prefer aluminium over carbon. You can dent it, smash it, scratch it, scrape it, and it keeps going. To me, it's the sweet spot between steel and carbon without the price of titanium.
