Frames

Bicycle frames

Frames (framesets) are the most important thing to pay attention to when assembling a bicycle. You can experiment and change all the details, but if you change the frame, you are actually changing the bike. A frameset is a set of frame and fork. As a rule, road framesets are chosen, because. Road bike rigid forks have nuances in construction and design, and it is desirable to match them with the frame. It is normal for a mountain bike to buy the frame and fork separately (although there are exceptions). When choosing a frame, a number of standards (headset, bottom brackets, etc.) must be taken into account, as well as the material of the frame.

The comfort of the owner during a bike ride depends on the correct choice of size (the so-called bicycle frames of various sizes). Riding the wrong size bike can lead to back and joint pain. Owners of an aggressive style of riding and fans of extreme disciplines should pay special attention to this parameter in order to avoid control problems and possible injuries. The size of a bicycle frame is determined by the length of the seat tube (verb).

Depending on the length of the seat tube, the model may be labeled as:

• XS (13-14 inches)
• S (15-16)
• M (17-18)
• L (19-20)
• XL (21-22) 
• XXL (23-24)

The easiest way to determine the right size is based on the height of the future owner. Riders shorter than 155 cm should use the XS frame, S is for 155-165 cm, M is best for 165-180 cm, L is 170-185 cm, XL is 180-195 cm, and XXL designed for the tallest people (from 190 to 210 centimeters). Since the optimal size also depends on the characteristics of the physique, it is advisable to try on the bike before buying. Stand directly above the frame, lightly touching the saddle, and make sure the distance from the crotch to the top tube is 50-150 millimeters. Try adjusting the saddle and sit on the bike, judging the degree of comfort. Those with long legs may need a bike larger than the standard size for a certain height.
