Dunlop are not that common around me. But I will say it's a nice working valve. And am not sure why there not more popular. One of those bikes I tensioned didn't have the roundest chain ring so I kind of found middle ground. The Fuji tensioned well. Very quite and smooth. And my old trek single speed I'd say I got a bit tight. It freed up after a couple rides and has smoothed out nice. I have an A.C.S. freewheel. There cheaper version. Oiling the freewheel does make a difference. Thank you for commenting.

@@albikes8484 Thanks for the reply! Oh, ACS is pretty nice even though it's cheap. I have one 16T ACS freewheel (not in use right now) and two 18T Dicta freewheels, which are also very cheap. Acs seems to have more encagement points than dicta. I also have not cheap 18t blb royal freewheel which has a lot of encagement points but I find it dragging way too much for my liking (and thus quite loud as expected). Oiling hasn't made too much difference with it.

@@Pianist203 Through the years ive sold and installed lots of Dicta freewheels. They work they last as long as your not a torque monster or a bmx racer. Nowadays that freewheels arnt the norm. The ACS mainline is almost the same price as the dicta. And cheaper at some places. Ill admit to just going with acs because it was a brand i was familiar with.
