This is a mood, especially when I use a road bike, I am using it hard. 53 39 I’m using 11 25 rubles in the middle I do not understand where curiosity comes from. The world is not flat friends, it is not worth breaking our knees. The professors competing on the world tour do not use the ratios you choose in the Italian and French competitions, which have tough climbs. Although Turkey is a flat stage 2017 tour of Istanbul had 28 rubles in most of the racers. I even saw 30 lu rubles in some racers. I think we should get the most suitable rates for not being able to change gears according to our path

Crank 50, 12 rubles You see 60 km in 12 teeth straight. The pedal does not turn up to 75 km downhill. You can not go faster on 52 mirrored roads. You can not be more wasted. The gear ratio is not important. Your pedaling speed is yours.

If the age is young and the leg strength is very good, 52 36 pegs can be selected. But the ruble must be elected accordingly. Rubles like 52 to 36 inches should not be selected as 11 25. The ratio of rubles in 52 to 36 36 must be 11 30 to 11 32

The important thing is to make the sport healthy and constantly
