For a lot of men the belly and lower back are the last places to go, but it really comes down to genetics. Some guys retain more fat in their legs and can get a 6-pack at higher BF percentages than others. One of the better analogies I’ve heard is it is like emptying a pool of water and belly fat (for many men) is like the water at the bottom of the deep end. You can’t just drain that area and need to drain the entire pool before you can really drain that area.
I’m similar weight but a little taller (178cm.). Belly and back seem to be the last places to retain fat for me and I still have a little belly but have quad veins popping out and good definition and vascularity in my arms and legs and chest. I can also see a 2 or 4 pack under the right conditions (angle, lighting, etc.). I think to get to a 6-pack I need to be under 63kg, which is really challenging for me. I would look super diced though and I’m sure my calves would inspire fear on group rides, so there is an upside. 
But I will not do it at the cost of performance.
I’ve been watching some body building focused youtube channels as they help give me some perspective on what it takes and body composition in general. They aren’t all directly applicable and aren’t focused on getting lean while maintaining endurance sport performance but I have some some of the techniques useful. Paul Reveila and Greg Doucette have been getting a lot of my recent views. Greg has been kinda high drama for my tastes recently though, but he does Zwift so I cut him some slack.
