樓主大大未經訓練 也沒有特別騎空力車可以輕鬆上35km/h avg. speed真的非常厲害了
參加world tour應該都會有不錯的成績

Gear table...可以幫你算齒比/迴轉速/速度的關係

tt世界紀錄
itt今年應該有機會被推到均速55km/h以上

這些因素都會讓你再更快
1. A time trial bike in a very aero position can add an extra 3-4 km/h (see: difference between road bike and TT bike)
2. Passing traffic on dual carriageways can add an extra 2-3 km/h
3. Very smooth roads – smooth tarmac can add an extra 1 km/h
4. In a 10 mile time trial, with a tailwind of 20mph, I once averaged 56km/h. Into the headwind on the return, I averaged 36 km/h. Wind is important.
5. If you can average 32-34 km/h on the flat on a road bike, you may find you can get close to 40km/h on a time trial bike on a fast course.
6. If you cycle in the wheels – behind another rider, you can save 20-40% energy. In the middle of a large peleton, it is said you can save up to 50% of your energy. You can probably ride 3-9 km/h faster. Average speeds for team time trials are often 3-5 km/h faster than individual time trials.
