The OG 1090 cassette’s main cogset is created out of a single forged form and in a complex series of operations that are CNC-guided, it is then heated and shaped into the finished product. Combining titanium’s weight with solid steel’s unrivaled strength and stiffness, it gives meaning to the words “highly durable”.

Lightweight: Innovative CNC‘d chromoly steel construction.
Durable: 35% harder than titanium!
Stiff: 15% stronger than its competitor.
OpenGlide technology allows for smoother transition between gears.

2011 Hope Integrated Cassette

2011 hope components 1 300x201   2011 Hope Integrated CassetteFor early 2011, Hope introduces its integrated cassette with a retail price of £150. The new cassette has an integrated free hub. It’s designed to be matched with Hope Pro 2 and Pro 3 hub wheels. What makes the cassette stand out is that the free hub body and sprockets are already part of each other.

As per Hope, the total weight of a Pro 2 wheel with the integrated cassette is 20g lighter than that of SRAM XX fitted sprockets and free hub. The new Hope cassette is definitely more affordable and you won’t have to worry about free hub splines any longer. There is also no need for a lockring to hold the sprockets. You now have the option to use a 9T cog, extending your cassette’s range and you can also drop a chainring from the front to even go lighter.

The 2011 Hope Integrated Cassette has a…

SRAM mainly known for their drivetrain components pushes the bar once again by taking the SRAM cassette that is apart of the XX groupset and making it available in 9 speed guise. Seven of the cogs are CNC machined together, which was put together by a block of billet steel on the XG999 cassette. The SRAM XG999 Cassette 9 Speed is said to weigh 175 grams for the 11-32 cassette, but with SRAM a high retail price does come, with the SRAM XG999 Cassette 9 Speed retailing at $300.

Upgrading to 12-29t instead of the regular 11-25t or even 11-27t is the new Campagnolo Cassette. While many of us want to make our bikes lighter, you can do this by running a compact 50-34t crankset and have the gearing the same as a 53, 42, 30t triple crankset. Coming this month is the Record and Super Record versions, and will fit with standard Campagnolo rear derailleurs. The Chorus Cassette will release in February 2010.

While the steel is not as light as titanium, they are durable nonetheless. The SRAM PG 1070 Cassette 2010 is also designed to be quieter than ever before. The SRAM PG 1070 Cassette 2010 is compatible with either SRAM or Shimano chains, and it comes in 11 to 23, 25, 26, 28T, and 12 to 25, 26, or 27T.
