I had the Frequency i25, the biggest one. TBH I was slightly fed up with mangling flows (they do good for their weight but it’s still a compromise), and these were cheap and had close enough ERD to reuse the spokes, that was the entire motivation 😆 But it worked out really well. TBH I’d probably have been just as happy on these new DTs. These days Mavic and Stans wouldn’t get a look in with me though, they’ve stood still.
What makes it so complicated is that people talk about “strong” but really there’s at least 3 things here… strength, durability and toughness. Strength, how likely it is to break outright. Durability, how long it lasts in normal use. And toughness, how well it deals with hits that don’t break it. So frinstance a Flow Ex is strong but it’s not tough, they dent easily and the low rim height means dents that you could straighten out on an old Flow can kill them outright. A 721’s strong and tough but ime not as durable, mine cracked all to buggery.
And everyone’s got slightly different requirements, I like low pressures and lighter tyres so I kind of need tough, I’m not heavy though and I ride fairly light so I don’t need as much strength for the big deathblows. But I was let down by the 721s as there was no point for me in big strength that couldn’t also last a long time. But that’s just my bias.
Oh aye, and with DH you have to throw in price and convenience of replacement too, because unless you go with massive bomber wheels you’ll break them sooner or later.
So I guess what I’m really saying is, don’t assume someone else’s killer app is great for you.
