Road bike size and height selection

         The first thing you need to know is that the frame is the soul of the bike, especially the road bike, and the appropriate frame size determines whether you can ride happy and ride cool. If it is too large or too small, it will affect your riding posture, causing you to ride harder than others, and it may lead to sports injuries over a long period of time.

        Secondly, the two important parameters of the frame size should be mastered.

       The first is the length of the riser (sitting pipe) A, and C is the length of the upper pipe (horizontal pipe)

Brand vehicles are generally produced in standard fixed size, but the same model is mostly produced in a size with an interval of 2 inches, for example: the same car is only 16, 18, 20 inches, or some cars are only 15, 17, 19 inches of frame. Just like buying clothes will be divided into S, M, L, and the different manufacturers of the risers have different standards, so this value can only be used as a reference and a rough estimate.

So here are some basic criteria:

Select the road vehicle according to the riser size (most road vehicles will mark the frame size XS/S/M/L) :

Height (cm)———— Riser size (cm)

160-172————46.5(XS)

173-178————48(S)

179-185————50(M)

185-190————52(L)

Select the road car according to the size of the upper pipe:

49(+-0.5cm)————150-160cm height;

50(+-0.5cm)————155-165cm height;

51(+-0.5cm)————160-170cm height;

52(+-0.5cm)————165-175cm height;

53(+-0.5cm)————170-180cm height;

54(+-0.5cm)————175-185cm height;

         The above is the general recommended value, short legs elderly, try not to exceed the recommended value, the size of the road car can be small not large, we should remember that the frame is the soul of a bicycle, be sure to choose their own, not forced, less than 160 friends generally recommend BMX road vehicles.
