2008 Sram pg970 DH 11-26 cassette ?

325g on the site...what makes them better for DH?
The PG970-DH was one of my fav new products for 08. The cogs are all individual and not connected to a spider. This way you can remove those you don't want/need (if you only run 8 or 7 gears for example) or replace damaged/worn ones. They are also all solid (not drilled out) so are nice and stiff. 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. Finally, they use an 11t vs 12t small cog so they are better for high speed courses when using a 36t chain ring as is the current trend.

I wonder how some freehub bodies will fare with individual cassette cogs. Gouges?

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.
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.
a 36T ring is not enough even for moderate speed courses! the rear cogs should be connected by a couple of removable pins to hold everything together (on a 11-32 970), not sure if they really are on the 11-26 970 though.
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.
good to know. BTW, who won the worlds this year?
What about this one:
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.
Bummer and it seems a bit overpriced.
It's in the ballpark of the other highend road cassettes. Campy has a stupid expensive all Ti one that's around $400 retail.
I've got one of the 2008 SRAM DH cassettes if anyone is interested in trying it out. It looks cool, I just have all my bikes set and don't need it. I got it with some other stuff as a thanks from SRAM for a favor. No, not THAT kind of favor, it was bike related.
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:
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).

Pricey in the US, but not too bad in the UK when compared to paying UK prices for dura-ace etc. I pay a lot less than the prices they show on there because I only have 6 or 7 cogs (7 now I think, 6 on my last one that got sold with my 222). And the cogs I don't have are the big expensive ones.
Well most people don't get new cassettes 2 a weekend! So ya....think about that idea for a second.
neither does sam hill...
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.
I can't recall now, and I can't find the email. The 6-speed 11-24 I bought in 2003 was $79 inc shipping (~ £40). That weighed 108g including lockring.
For reference, current prices at CRC for dura-ace is £55 (12-25) or £65 (12-27)!
The current 7-speed 11-26 I have is a little weightier and no doubt more expensive due to inflation, more cogs and larger cogs. I'd guess about $100 but I really can't remember, sorry!

I cracked a cog on my 07 Pg970 road cassette this past weekend.
Is DA available in 11-26T? I've just seen it in 12-26T...
And Ultegra?
No Shimano 11-26 cassettes.
shimano has the 11-21 , 11-23, 12-25 and 12-27
sram has the 11-23, 12-26 and now the 11-26 DH cassette i'm interested in
i do have a old sram 11-26 with black plastic spacers and black steel lockring but as far as i know it must be pretty old
because sram has only been doing the 12-26 for awhile now

ooohhhh prettyand what about this?
Its a cassette, are you f-ing serious? You turn the pedals, the back wheel spins. For the love of god. Now I have to go unsubscribe from this thread.
Now what should we do if we can't afford an expensive cassette? I find it much easier to take a 11-32 PG970 and trash the 2 large cogs, which wlll save over 140 grams so you land somewhere near 180g for the whole setup, still having a 11-24 range. A dedicated downhiller can go further and get rid of the 24t cog, getting the whole thing under 140 grams. Nice, clean and cheap, isn't it. Another advantage is safety, so you never damage your parts when your hanger bends towards the wheel.
I've run the Standard SRAM PG970 12-26t road cassettes exclusively for the last 4 DH seasons and never tweaked one. .
My PG990DH will be here tomorrow. And I have a race this weekend, I'll give an update after I get it on the bike.
