SRAM's Cassette performance is optimized by tooth profile and shift ramp design for quick and positive index shifting. The cassette shifts efficiently and positively in all high performance situations. There new cogset features a semi-spidered construction for a maximum stiffness to weight ratio and is available in seven optimized configurations to best match a wide variety of uses.
About Cassettes & Freewheels
Cassettes and freewheels for bikes are a cluster of sprockets in a range of sizes offering a multitude of gear ratios. The difference between the two is, a cassette slots onto the freehub, which has the ratchet built in and is then secured with a lockring, whereas a freewheel is a cluster of sprockets built around a ratchet and threads directly on to the hub. Cassettes and freewheels come in many ratios, close ratio is when the number of teeth increase in small increments of 1 or 2 at a time, whereas a wide ratio is when the teeth increase in larger increments of 3 or 4 at a time. Most systems will use a cassette hub as these allow for a wider bearing spacing and increased axle life, you can also fit a larger quantity of sprockets onto a cassette hub with 11 speed systems now becoming available. With cassettes you must use the appropriate spacing for your gear levers and rear mech, Shimano and Campagnolo are not interchangeable so you will need to match the cassette to your levers for smooth and precise shifting. Sram and Shimano chains and cassettes will work together as they use the same spacing.

Magazine reviews for SRAM PG1070 10 Speed Cassette - Road
Review from Cycling Plus
As with SRAM Red, the three largest sprockets on the Force cassette are supported on a spider, but SRAM's second-tier groupset doesn't have Red's titanium sprockets.
Instead, it sticks with heat-treated steel. These aren't as light as titanium but they should prove more durable in the long-term.
The Powerglide cassette and chain combo is claimed by SRAM to be quieter than before, but comparing the noise from 2009 and 2010 setups we really weren't able to detect any difference. The profile of the Powerglide teeth did contribute to consistently smooth shifting though.

Product Q & A
Ask your questions and share your answers.
Will the SRAM cassette 12 - 27 be compatible with my present set up? Is this SRAMs 'equivalent' to ultegra range.
(I don't much want to change to the new Shimano 6700 range 11- 28 casette - too wide - and there is some doubt re compatibility anyway I believe)
Your wheels must be shimano 9/10 compatible, not shimano 10 speed only. I.e right now you are using the small spacer before mounting the 6600 cassette.
Not many wheels were made shimano 10 speed only, and only by shimano themselves, and even they have stopped doing that now.
I run RED and FORCE gears on our bikes and have wheels with both 5600 (105) and 1070 cassettes and have not issues.
Interestingly, I borrowed a wheel at a race a while ago with a 6700 cassette and it ran fine.
As far as "what is the equivalent' - FORCE and RiVAL are very close in quality to Ultegra - if you are a weight kind of person, they are very close (the new APEX is probably closer to 105), with RED.
I use 1070 with RED as I can't see the justification for the price and the performance that it offers for an amateur!
Be sure to check if your chain is still within specification, because if you put a new cassette on with a worn out chain, you will wear the cassete out really quick
it is still usable, but you just need to avoid this combo (and maybe the one below it) but you really should be avoiding this chain cross anyway.
I have 11-28, 12-25 and 12-27 cassettes (SRAM 1070 and Shimano 5600) running on our bikes (SRAM Red and SRAM force and the chain is fully accommodating.
The limiting factor is the cage length, so a 28T is as big as you can go.
Going down would mean a lower quality chain than the cassette which is ok but not optimal.
The number of links is measurable from your existing chain, on a road bit it will be the smallest available anyway. I tend to need to cut off 3-4 links. Check Youtube for videos that explain all this.
Thanks for your help
All SRAM and Shimano 10 Speed cassettes are fully interchangeable with the only limiting factor being cage length.
I have both SRAM Red and SRAM Force short cages so the maximum sprocket is a 28T.
I currently have a Shimano 5600 12-25T (10S) and SRAM PG1070 12-27T and 11-28T cassettes running on our bikes and the wheels are fully interchangeable with no performance difference or need to re-calibrate the shifting mechanism.
Further, I have provided my spare wheel on occasion to other parents with 10S Shimano needing a quick rear wheel spare at a race events with no issues.
Hope this helps
