Hold on, this is Retrobike, the system is effectively a threaded headset idea which we all should be familiar with and there's nowt wrong with checking and retightening your headset, thats just good maintenance.I have a couple of bikes with the BBB extender, I think its a great system. If you want a system as good as the original then get some forks with a long enough steerer
Easier said than done if you ride gates like my huge M-Trax
Never met me have you, minimum size of my bikes is 21" most are about 23" and once I had a 25 incher. As I say I have several bikes with the system and they get used at Glentress, not famous for its soft terrain and I dont find problems.
Paul has had some experience and you have no reason to disbelieve him. I have some experience but you do disbelieve me, a fellow could find that hurtful................merry christmas
