>>1204626 0.01mm in machining or a cnc product is shit, but it is fucking great on a welded structure that makes almost 1meter long. It is this tolerance on the whole frame distance. admit there is a 0.015mm twist between head angle and rear triangle the frames goes to be crushed. And this tolerance is something you won't even feel by riding, but it is just that they provide the straightest frames on the world.
