SRAM Downhill Cassette PG-970 DH
Monday, February 25th, 2008
SRAM created a cassette aimed for the downhiller. Check out the details inside of their PG-970 DH 11-26 cassette.
If you’ve ever bent a cassette cog on your downhill bike, this cassette might be what you’re looking for. While it’s still possible to bend a cog on this cassette, SRAM has designed all of the rings to be separate and has a gear-range that most downhillers will enjoy. It utilizes SRAM’s Powerglide II technology which has got ramped cogs as well as a tooth profile to make sure shifts go smoothly.

The 11-26 PG-970 DH cassette consists of the following cogs 11,12,13,15,17,19,21,23,26 which provides a nice range of gears for a downhill bike.

There are red alloy spacers that fit in between each individual cog. If you’ve got an aluminum freehub body, the single rings may dig into the body easier than a cassette whose cluster is attached to a spider to spread the load out more.

The two biggest cogs are solid cogs to make them stronger and more resistant to bending. All of the cogs are heat treated SAPH-440 steel cogs separated by a full set of precise aluminum spacers to combat flex as well. The cassette does have a weight penalty due to its design but if you’re looking for a new cassette for your downhill bike that is stronger, the PG-970 DH may fit your needs.

One of these came on my 08 team dh. The 26 was warped from the factory. Crapo. The weight is crazy stupid too, get yourself an ultegra or 105.

Or ask any buddy who has been road racing for several years if you can have his old DA 9spd cassettes. He will be happy to get them out of his garage.

agreed - a Dura ace cassette that gets mashed and brutalized by roadie weighs 180g or less. a DH racer does not put a cassette under more load than a roadie. so the only reason to beef it up so much is to withstand a direct impact and how often does that happen? interesting idea but not really all that useful or worth it IMO.

when you drop something with your brakes on, if you put a bit more weight in your front foot you can be sure you’ll have more load in the cassete than armstrong ever had

think about trials riders they must really put a lot of load on their cassettes

Yeah, very heavy. can’t remember the last time i bent a casstte and the single cogs will eat any alloy freehubs!

Trails riders all run singlespeed these days. I’ve seen a few cracked hub shells from the old landing with the brakes on trick, but never a cassette. I’d say these are more prone to bending, theres little lateral support and the load isn’t dispersed as well. Anyways I have one here, $50 if anyone wants one

Been riding this cassette now for a couple months and it sucks… Its pretty f-ing heavy for a cassette and The Up-Shifts lag…. Im switching over to Ultegra once I get the $$$…
