Excuse me, what does the compressed frame of a road car mean?
In fact, one of the great advantages of the compression rack is that the manufacturer saves trouble very much. In the past, the diamond rack may be forty or fifty, and a number should be given every 1CM difference. Generally, as long as it is a compression rack of S, M, L M, L, it is a big deal to get another XS, XL, and then the user can adjust the fit by the seat tube, which saves the manufacturer a lot of trouble.
