It is need adaptor or something like that?

Oh yeah... Duh! Cyclust is right.cyclust said:The Q-factor will not be any different than it would be in any other framre with a standard threaded BB shell. The adapter is the same width as the BB 30 shell, and is the correct width for standard bottom brakcets as well.
