This freewheel is an excellent alternative to cheaper (rough running) freewheels or more expensive White Industries freewheels. I have three (3) of these (16T, 17T, and 18T) that I alternate on two bikes for commuting. No issues what-so -ever ( 1 year of use on oldest) and smooth with a strong pull and fast! These are quality freewheels and a good buy. As soon as I replaced my older freewheels (cheaper) the advantage was immediate (smooth with Immediate engagement). I am running 18 Single Speed chains and they work well with these IRD freewheels (good mate). Also a good match (total combo) with RACE FACE Cyclocross narrow wide chain rings.
Just put one on my Paul WORD hubs and it is very nice. Immediate engagement but kinda loud, I feel like I am fishing with a loud reel. One comment. I should have chased the threads. Totally ripped thru my WORD threads but the integrity of the threading is still there. The IRD threads are long and strong.
I like this freewheel. I screwed it on my flip-flop hub and off I went. It's a quality product and good-looking, too. Almost ordered a freewheel that cost 2x as much, wanting to make sure I got a quality product, but now I'm very glad I didn't This IS a quality product! You won't be disappointed if you're considering buying it.
