which of these two is the toughest, which is the lightest
im looking at buying a set of wheels for aggressive riding most likely from superstar and these are some of the options.
what would you preffer and why?

en521 because I run them and i'm very happy with the abuse they can take. They are lighter iirc.......If you don't intend to run tubeless...why bother with stans?0

yeah i might try it out and see what im missing, not fussed though as i could run ghetto tubeless with the mavics, just want to find out what is the best rim for the job0 -
all weights of rims are on the respective manufacturer's websites as well btw.0

Flow is 470g (or 510g if you want white), EN521 is 540g. Flow is also wider, and the lower rim edge combines with that to give you more volume from an equivalent tyre.
As far as strength goes, not so easy, it's not an absolute. Flows are softer- ie the edges dent more easily- but they don't seem any less strong overall than my 721s, or less stiff. 521 is eyeletted and the Flow isn't, which ought to mean the 521 has a better long-term fatigue life (in practice, I've seen Mavic rims fail round the eyelet instead...) I don't really expect my rims to have a long comfortable life, I figure I'll kill them with stupidity long before fatigue gets them). So it's give and take.
Both are strong, though... I just moved my Flows onto the dh bike, guess we'll see how that goes in the long term.Uncompromising extremist0 -
I stand corrected on weight........ although for 30g Vs the white ones i wouldn't see it as an issue really.0

Aye, the weight difference there is daft isn't it! 40 grams of white paint. I'd really like white rims as well for the big bike, since i'm a tart but that totally offends my sensibilities.Uncompromising extremist0

Til I plow into a tree or rock or case a jump like a big fanny
But I think they ought to do fine. Might swap back for the endurance dh, if only because I'm relatively likely to have to ride a flat tyre down the hill and they're definately tougher from that perspective. Uncompromising extremist0 -
typical, i was eying up the flow white rims lol, i was reading an article about heavy wheels makes for a heavy ride due to inertia etc0

I'm 97kg and started riding my bikes again when I was 115kg. I run 32 hole 521s on both bikes and have never had an issue despite my best attempts to ruin them. Can't comment on the Flows, haven't used them.Trail fun - Transition Bandit
Road - Wilier Izoard Centaur/Cube Agree C62 Disc
Allround - Cotic Solaris0 -
As above, I run 521s with SLX hubs & plain-gauge spokes on the Ramones and they are pretty much indestructible. Stiff & taut with zero flex but not harsh. There is maybe slightly more inertia when accelerating at low speeds when compared to an almost identical set of wheels I have with 719 rims but that's to be expected and a small price to pay for the lack of twanginess0

Both rims are good.
What width tyres are you using? The flow will give a better tyre profile on anything bigger than 2.3 as it is wider.
I am currently riding flows, built by hope, then bedded in and retrued as soon as i got them. I used a tensionmeter to achieve the correct tensions, which are lower than i'd usually run, i'm impressed with the results.
They've been on my bike 3 months and have not had to do any tweaking to it. Been doing high speed peaks rocky descents, purposefully bashing hard into rocks to see how they last, zero dings. Been doing ~15ft long road gaps, 6ftish drops to pretty much flat, 20ftish doubles, they haven't missed a beat. This is all on my pitch, so the the rear wheel is taking more abuse than it were on a DH bike.
Also running tubeless easy peasy with regular single ply maxxis tyres. The tubeless with any old tyre is another major plus for me with the flow.
Warranty is also excellent on the flows too if you do have a spoke hole pull through, experience of a buddy.0 -
I have the 521 on hope hubs, never had a problem with them and I do everthing on the bike had many offs, still nice and tight, can't comment on the flows other than the white look, bling!0

sounds good, yeah i plan to give them some stick, take them down Munro's, orange routes and a bit of DH if im up to it as the wheels will be going on a ragley blue pig HT , it will either make me or break me 0
