My commute to work initially climbs very steeply in 3 km from 400m elevation to 640m and then the remaining 80 km is fairly flat except for two 100m high hills. On my other main route (115 km long), the elevation goes from 400m to 150m over gently rolling terrain.

When climbing hills that are too steep to maintain speed at full throttle in 5th gear, I drop to 4th and maintain a speed of 65 to 70 km/h, even steeper and it drops to 3rd gear and 55 km/h.

Going downhill on those 100m high hills, I take the gravity ride in FAS at speeds up to 120 km/h (road, speed limits, and traffic permitting). On longer downhills (or on shorter downhills once I reach the maximum speed I'm willing to go) I'm using engine braking in 5th with full fan and A/C and occasionally open windows for additional drag, with the occasional application of friction brakes as needed.
