Do you actually ride around in the Kingdom of Saudi Arabia in Jeddah??
I worked there for a while, it gets really hot esp this time of the year and bound to get hotter in July, as high as 120F!! Still hot even very early in the morning!
. I actually miss the place, great food (the bbq Kabsa chicken especially and the "burritos"), fun times!
My inseam is 83cm and matched for 170mm crank. But I can hold higher effort zones for longer periods with 150mm crank.
To be honest, my very first experience being a roadie at a very young age, I went with 170mm. I don't recall having an issue about it apart from saddle soreness. But then my next bike had 150 mm. I spent a lot more time riding on the 150mm crank bike. Now I'm back to 170mm size crank and now my legs are complaining.
