Well DH is a bit different on the power thing. On the road you wind up sprints it's a constant acceleration and it's usually started from a pretty good clip on the smaller cogs. In DH it tends to be more instant from a slow speed and can be on the larger cogs which are easier to bend.i don't see why dhers need stiffer cassettes, because i doubt sam hill can put the same amount of power down that most professional road racers can.
I've been running SRAM spiderless cassettes (11-23, 11-26) for a season and a half, and both Hadley freehub bodies are fine. I'm 230lbs and put out a ton of torque (especially when out of the saddle mashing on burst climbs), and have broken a few cogs, but the hubs have been fine.I wonder how some freehub bodies will fare with individual cassette cogs. Gouges?

good to know. BTW, who won the worlds this year?a 36T ring is not enough even for moderate speed courses!
Speedgoat.com said:Unlike most cassettes, made of a spider and individual cogs, this one is machined from a single piece of lightweight steel, in an operation which ties up a milling machine for over an hour per cassette. After machining the steel is hardened and nickel plated for added durability. Added to that assembly are the smallest two cogs, the lockring and an aluminum backplate, producing a finished component that is stiffer yet weighs less than comparable cassettes. The OG-1090 will be available in 11-23 and 11-26, and is expected will retail for $230.
It's only available in 10 spd at the moment.What about this one:
Bummer and it seems a bit overpriced.It's only available in 10 spd at the moment.
It's in the ballpark of the other highend road cassettes. Campy has a stupid expensive all Ti one that's around $400 retail.Bummer and it seems a bit overpriced.

Not sure what your time is worth, but given that the cassette requires an hour of machining time, plus the nickel plating and time, plus the additional cogs and lockring, the R&D time, the programming time, QA/QC, and the "bling" tax, it seems like the pricing is probably spot on.Speedgoat said:Unlike most cassettes, made of a spider and individual cogs, this one is machined from a single piece of lightweight steel, in an operation which ties up a milling machine for over an hour per cassette.

Hahaha, I've been running 6/7speed 11-24/26 cassettes for a few years now, the ones I have from cycle dynamics come in at about 100-120g (much lighter than dura-ace).i read that they are like +300g
is that right?
Well most people don't get new cassettes 2 a weekend! So ya....think about that idea for a second.i don't see why dhers need stiffer cassettes, because i doubt sam hill can put the same amount of power down that most professional road racers can.
neither does sam hill...Well most people don't get new cassettes 2 a weekend! So ya....think about that idea for a second.
My titanium cassette is individual cogs with individual spacers (I have two sets of spacers - one for 8speed, one for 9speed) and my freehub has lasted just fine (hadley) as did my ti hope bulb one.300+ grams are stupid heavy for a 11-26T. Get a Shimano DA. Better durability, much ligther and it want eat your freewheel.
Is DA available in 11-26T? I've just seen it in 12-26T...300+ grams are stupid heavy for a 11-26T. Get a Shimano DA. Better durability, much ligther and it want eat your freewheel.
No Shimano 11-26 cassettes.Is DA available in 11-26T? I've just seen it in 12-26T...
And Ultegra?
I've run the Standard SRAM PG970 12-26t road cassettes exclusively for the last 4 DH seasons and never tweaked one. .Standard PG970 12-26t road cassettes were susceptible to bending the largest two cogs as they were not supported enough, I haven't tweaked either of my proto PG970-DH cassettes all season.
