I already have the Ferdi brace. 5th gear was worn, and has been popping out quite forcefully lately. When it popped out, most of the time I would downshift to 4th to get the rotational speed back up, and then gently grind it back into 5th. Otherwise, it wouldn't go into 5th. On Monday, it popped out, and I tried to downshift to 4th, and it wouldn't go. Then I found out it wouldn't go into 2nd or reverse either later on.
