Silent and smooth.

With the introduction of the Force and Rival road groups, SRAM brought some long-overdue, fresh-thinking to component design. Thankfully, SRAM's creativity and innovation didn't stop at components with show-stopper aesthetics like shift levers and cranksets. Instead, it's evenly extended to parts that're traditionally thought to be rather mundane, like the cassette. And unlike other cassette manufacturers, who maintain multiple models of cassettes despite the minimal differences between them, SRAM did the sensible thing: It offers a highly scaled back range of cassettes. The standard model, found here, is known as the PG-1070 Cassette, while the deluxe model is known as the OG-1090.

Whether you're riding a Red, Force, or a Rival-equipped bike, the 'PowerGlide' shifting of the PG-1070 cassette will provide crisp, positive shifting under any circumstance -- whether it be a mellow spin, or at max power on a steep climb. And, unlike either Dura-Ace and Record, the PG-1070 weighs in at a scant 220 grams without having to resort to easily-worn titanium cogs. Rather, the PG-1070 is made from durable heat-treated steel, giving you tons of mileage before you'll need to replace it.

The PG-1070 is available in several ratios. Its spline configuration allows it to fit on any Shimano 9- or 10-speed freehub, and it's compatible with any 10-speed chain: SRAM, Shimano, or Wippermann's S-series chains. What SRAM suggests, of course, is that you use one of its 10-speed PC-1000 series chains for optimal shifting. And, in addition to the aforementioned, the PG-107 includes a forged, anodized, and laser-etched lockring.

The actual weight of the SRAM PG-1070 Cassette varies with tooth count, but for reference, the 11-25t is a claimed 224 grams.

Was great until I broke it

  • Familiarity: I've put it through the wringer

Been riding this cassette hard for the last few years. Managed to bend a feed ramp that eventually caused it to fail, but with how many miles I put on it I can't really blame the cassette.

FYI - SRAM lock nut is silver not black

    I love the way these cassettes fit together and install with ease. This is well crafted and solid but light. Built up a fat bike in my basement with an SRAM X9/X7 drive train to better mimic the 2014 OEM. Decided to have the shop run the cables so to be sure it will look as good as it shifts although most of the build has been super straightforward. A little nervous leaving it there after babying it the past 2 weeks. Will add to this review once the bike is done and I have some snowy rides in.

    Perfect gearing

    • Familiarity: I've used it once or twice and have initial impressions

    Great range of gears for 52/36 chainrings up front. Can only be outdone by an 11-speed set up. Able to keep same cassette for all types of riding in San Diego/Southern California (flattish coastal rides, 4-hour rides up/down Mt. Palomar, the 100-mile Ride- Around-The-Bear in San Bernardino Mtns, 100-mile Tour de Palm Springs, etc.). Runs quiet and smooth with awesome Shimano reliability. Needed to add 2 links to my chain to clear the upper pulley from the 28 tooth cog and having the B-screw completely turned in as far as it will go (may need to go with longer B-screw). This is on a 6800 Dura Ace rear derailleur.

    Great Quality, Easy install, very quiet

    • Familiarity: I've used it several times

    I put this more all-mountain cassette on a more downhill oriented bike at the suggestion of a buddy that uses it on his bike. He said it would make any pedaling uphill easier, I chose the 11X32 and so far its been great. It's been on my bike a couple weeks and no complaints thus far. May upgrade at some point, but for now it is working well and weight is not a huge issue.

    A change of gearing, worked out great!

    • Familiarity: I've put it through the wringer

    Was referred by a seasoned road bike rider to change into this cassette from what I was riding on. A little bit of changed up learning curve, but now I have great gears for climbing, and other big chain ring gears for flat riding. No problems.

    Make Sure To Get The Right Cog Size

      I got caught with a worn out chain that had also worn on my cassette. No bueno but will be sure not to make that mistake again and happy to be able to get a reasonably priced one here. Make sure you understand the different cog sizes and what's right for your bike!

      Great cassette, durable, reasonably priced, and will keep running well for you for years!

      Great Cassette

      • Familiarity: I've put it through the wringer

      This is a great product, relatively light and well built. My last one lasted me 6 years and thousands of miles of riding. I find the 11X26 is a good cassette with a compact in the front and I live in the mountains of Colorado, unless you live in a really steep hilly area like Vermont, then in that case go with an 11X28.

      Unanswered Question

      I have a specialized roubbaix with a 1070 Cassette, 11x32 and a Apex mid length rear derailleur. I want to go to the 1070 11x36 cassette. Will my current Apex mid length derailleur work? If not what would you suggest?

      Have 10 speed Shimano Ultegra group. Can I use a SRAM PG-1070 12-32 cassette ? What derailleur works for this ?

      Good Price, OK weight, good quality

      • Familiarity: I gave it as a gift but have feedback to share

      Certainly, the more expensive ones are better, but it is hard to justify spending more than 70 bucks on a cassette.

      I have a Shimano Ultegra 11-28 rear cassette and derailleur right now. If I use the SRAM 11-32 will it work with my current rear derailleur?

      If you have a short cage derailleur the maximum stated cog size is 28t--going to a 32 would necessitate a long cage RD. I recently moved from a short to long cage Rival RD to go from 27 to 32 teeth in order to accommodate some of the really steep hills in the Seattle area where I recently moved. I'm glad I did. Very slight shifting delays compared to short cage, but that is nothing important to me.

      upgrade by downgrading

      • Familiarity: I've put it through the wringer

      I had the og-1090 (11-25). It was loud.

      I switched to this and i got to go up to a 12-28.

      I notice no difference in weight/watts required or shifting performance. If anything this one seems better cause it is newer.

      How I could use 12-36 cassette on Sram Red...

      How I could use 12-36 cassette on Sram Red Rear Derailleur...

      Is it impossible????

      A Sram Red rear derailleur will only accept up to a 28 tooth cog, if you want to run something bigger the Sram Red WiFLi rear Derailleur will accept up to a 32 tooth cog.

      I just posted this as a review instead of a question, can the 12-32 cassette be run with the standard force or rival derailleur? Is the wi-fli type with the long cage really necessary?

      with this cassette, which chain should I select

      any SRAM 10-spd chain would do the trick. PC-1050 is a great budget chain.

      Best Answer

      I have used SRAM chains and a Shimano Dura Ace chain with the 1070 cassette. I find the Dura Ace chain is quieter, but either will work fine.

      Likewise, I am currently running a Wipperman & it works fine. I don't think it's any quieter...I don't think its lasting any longer than the SRAM (but I ride old-school, with no electronics or measurements xcept my wrist watch, so I don't have any mileage to report). But it shifts as good as SRAM despite the warning on the chainring that states "only use SRAM chains".

      Works great!

      • Familiarity: I've put it through the wringer

      The PG1070 system is great! I run the 11-26 and live in mountainous area where climbing is common. Love this system and SRAM makes great cassettes. You can't go wrong with the quality............your only decision is what gear range you want!
