I just noticed that the old documentation was recommending to apply low-strength threadlock compound for frame assembly but the new one does not mention that anymore. Any idea if it`s a good idea to apply something like purple Loctite 222 to frame bolts?
Thread lock can be useful but it has been found that frames rarely shift even if thread lock is not used. If used it should be the weakest you can get as it doesn't need to hold that much. Also if the frame has to be adjusted at all later then the thread lock doesn't do anything once the bolts have been loosened.
