SRAM PG-1070 Cassette $107.00
A cassette by ninjas, for ninjas.
With the introduction of the Force and Rival road groups, SRAM brings some long-overdue fresh thinking to component design. Their creativity and innovation doesn't stop at components with inherent sex appeal like shift levers and cranksets. It extends even to traditionally mundane parts like the cassette. Unlike Campagnolo and Shimano who insist on maintaining multiple models of cassettes despite the minimal differences between them (we challenge you to distinguish between an unmarked Chorus and Centaur cassette; ditto for Ultegra and 105), SRAM did the sensible thing: They offer a highly scaled back range of cassettes. The standard model is known as the PG-1070, while the deluxe model is known as the OG-1090.
Whether you're riding a Red, Force, or Rival-equipped bike, the "PowerGlide" shifting of PG-1070 will provide crisp, positive shifting under any circumstance -- a mellow spin, or at max power on a steep climb. Unlike Dura-Ace and Record, the PG-1070 weighs in at a scant 220g 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 9/10-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 their 10-speed PC-1000 series chains for optimal shifting. Includes a forged, anodized, and laser-etched lockring.
The actual weight of the SRAM PG-1070 Cassette varies with tooth count. For reference, the 11-25 is 224g.

What community has to say
- Familiarity: I've used it once or twice and have initial impressions
I just replaced the 11-32 with a 11-26 PG1070 and love the gearing. Quality as usual from SRAM. I have no complaints with this or any SRAM so far. I guess now the endurance of this cassette will be the tell tell of the ultimate what I think of it.
College Budget, Professional Performance
- Familiarity: I've put it through the wringer
Sram's 70 lineup has been a staple in my stable of bikes. Between cassettes and chains, I find it to the best trio of performance, weight, and their friend money. The cassette has a noticeable weight drop from it's thrifty brother, the 50 lineup, with more peepholes and an aluminum carrier cradling the larger sprockets. Durability is dependable for many miles and the ability to pull the cassette apart allows deep cleaning after miles of neglect.
Smooth as Billy D Williams
I needed (wanted) another gear for hill climbs in my area, so I exchanged my 11-28 (1050) for the 11-32 (1070). I have a compact crank 50/34. I don't miss the #14 either. I also upgraded to the SRAM 1071 chain. I did not have to change the rear Derailleur; the SRAM rival mid cage works. The 1070 cassette, along with SRAM 1071 chain is as smooth as Billy D Williams and as quiet as a church mouse. As I road past walls and through a tunnel, I noticed the drive train was really quiet. They shift smoothly, too. I am a happy camper.

I have full ultegra components with a triple on the front and an 11-27 cassette on the back. I also have a medium length cage derailler. I would like to put the SRAM PG-1070 11-32 cassette group on the back and have been getting mixed opinons as to whether my existing medium lenght cage is sufficient or if I need to go to a long cage. Does anyone know the answer?
To determine what capacity you need I have always used the following formula: cap req'd (T) = (BIG ring - small ring) + (BIG cog - small cog) and then based on that Shimano cages provide the following,Shimano long = 45T; medium = 33T. Hope that helps.

i am riding with a force crank set and rival derailers. what is the largest cog i can have on my rear cassette? will a 11-28 work or will it rub on my derailer?
An 11-28 will work with all Rival derailleurs. A medium cage derailleur would be needed to go any larger.
