Durable, lightweight solution for 10-speed drivetrains.

The SRAM PG-1070 Cassette, unlike many competitors' cassettes at this level, is made completely from steel cogs. SRAM’s design wizards, however, have managed to keep the weight of the PG-1070 at just 220 grams, without resorting to Ti cogs at the larger end of the cassette, which wear faster than steel, and contribute to faster overall drivetrain wear.

The PG-1070 will fit on all nine and ten-speed Shimano and SRAM-style splined freehub bodies and is compatible with all 10-speed chains, though SRAM of course states that shifting performance will be optimal with its chains.

Shifts like butter

  • Familiarity: I've put it through the wringer

Works great and is super shiny!

BLING!

  • Familiarity: I've put it through the wringer

I like the SRAM cassettes because they shift well. But additionally I like them because they look fantastic!

Did the trick

  • Familiarity: I've put it through the wringer

Got some new wheels to run with Red 10 sp group. The 11-28 worked out well, using a spacer on a DT240 11 speed hub. Didn’t even have to adjust the rear derailleur or shifter.

For the price, it does the job well

  • Familiarity: I've put it through the wringer

I run RED on my race bike and when you compare this to a RED cassette there are definite differences, but one of those is also the price. I have run 4 different configurations of this same cassette on various road bikes and tfor the price they deliver great value. The variety in gear ratios (now running an 11-32 on a climber) make this a great addition at a reasonable price point.

Love the wide range

  • Familiarity: I've put it through the wringer

I brought the 11-28 ratio because I am tired of swapping the 11-23 for the flat rides and 12-27 for hilly rides. Now I can have the best of both world! Shifting is flawless once you fine tune the RD.

I have a Di2 10 speed (11-25 Cassette ) and want to upgrade
1 To a 11 speed 12-32 ( or higher cassette )
2 The higher cassette is a ram 12-36
3 If this is not possible can I still get a Di10 medium rear derailseur and add a larger cassette ( either a -32 or -36)

Medium Cage will work for 11-32, for 36 you need a Large.

Basic Cassette

  • Familiarity: I've put it through the wringer

This is a great, reasonably priced cassette. Works as you would expect with super crisp shifts. Also come in a variety of tooth configurations.

stoked

  • Familiarity: I've put it through the wringer

great cassette. no complaints. weighed in as advertised, within a few 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

  • Familiarity: I've put it through the wringer

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. UPDATE: after 2 years in snow, mud, rain, and slop, this cassette is going strong, never skips, and is easy to keep clean.

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!

    Shram 12/32 cassette

      it went on and worked smoothly without any adjustments to the DA der and was quieter than the DA cassette. Life is good.

      Solid

      • Familiarity: I've used it several times

      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?

      does its job

      • Familiarity: I've put it through the wringer

      I have no complaints on this cassette. it's been a nice upgrade from my 2012 cassette.

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

      Yes, for the 10 speed bicycles, this is universal.

      did you ever get a response to this?

      I have exactly the same question/ concern.

      I want to swap 11-28 10speed ultegra setup with 10 speed 12-32 and am wandering if the ultegra derailleur will work or needs changing.

      ah -just seen the response -i need to change the derailleur to long cage...
