Thanks for the info and photos. The iterations indicate that Brompton does not consider the rack design to be matured either. The racks on our Bromptons are both pre-2016 but I have hard time figuring out how the current model is different. Checking the other Brompton I can see that its rack is shoved to the right too, but at this point not locking the wheel. Anticipating further work I placed an order for more mini hose clamps for the braces.
