CASSETTES
2010 SRAM XX Cassette
Many feel that the SRAM XX Cassette is the centerpiece of the XX group. It is an impressive feat of machining -- spin the cogset and the design is mesmerizing. Spin it on an acid trip and you'll be smiling in awe for hours. SRAM once again borrowed an idea from their Red road group when they ...read more
2010 SRAM PG-990 Select Cassette
SRAM is now offering their high-performance PG-990 Cassette in select anodized colors. Sure, most of the "wow" is the anodized aluminum five-arm spider, and we all know it's going to be dusted, mudded, slathered, and covered in less than a handful of rides. But since you'll want to make your new ...read more
2010 SRAM PG-980 Cassette
The SRAM PG-980 9-speed cassette is a kind of hybrid. The three largest steel cogs are riveted to an alloy spider for weight savings, stiffness and durability, while the remaining six steel cogs are individuals for economy. The three cogs take their spider from the ultra-high end PG-990, ...read more
2010 SRAM PG-970 Cassette
The PG-970 employs the same PowerGlide II ramp system that is found on the PG-990. Instead of pinning the largest cogs to an alloy spider, all the cogs - save the 11 - are bolted to one another. This is the cogset SRAM derailleurs and chains are designed to work with, though the cogs will also ...read more
2010 SRAM PG-970 DH Cassette
When you don't go uphill, what's the point of having a pie plate for a big cog? Nothing screams, "I go downhill fast!" like a narrow ratio cassette. Committed to the lifts and shuttles? You bet! SRAM makes the PG-970 DH cassette specifically for the gravity fans out there. It uses steel ...read more
2010 Shimano XTR Cassette CS-M970
Cassettes aren’t sexy. Unless they’re XTR. We didn’t think there was much left to do with cogs, but then Shimano went out and re-designed this cassette, with reprofiled, stiffer titanium sprockets in the four largest cogs. This means they’re lighter and shift better and there’s less energy ...read more
2011 Shimano XT Cassette CS-M771-10
For their Dyna-Sys 10-speed system, Shimano added another cog to their venerable XT level cassette. So like the previous 9-speed versions, the CS-M771-10 XT Cassette has the same Hyperglide tooth and ramp shapes to help the chain move effortlessly across its range. The XT 10-Speed Cassette ...read more
2010 Shimano XT Cassette CS-M770
The Shimano Deore XT CS-M770 Cassette takes all the ramping and weight-relieving of previous generations -- not like that stuff would go away -- and adds a cool new feature: pins on the backside of the tallest cog. At first, the innovation seems like sloppiness or poor manufacturing ...read more
2010 Shimano Saint/SLX CS-HG80 Cassette
There are three Saint/SLX specific cassettes, known as model number CS-HG80. They're 9-speed cassettes designed to work best with Shimano's Super Narrow HG for 9-speed chain. The ratios are 11-28, 12-32, and 11-34. The 11-28 has the following cogs: 11-12-13-14-16-18-21-24-28 (BG). The 21-28 ...read more
2010 Shimano CS-HG61 Cassette
Shimano has heard the cry for help, or more appropriately the grumblings from the trail as 29er riders lumber up the hills. Their response is the CS-HG61 Cassette. It's a fact that existing gearing was optimized for 26" wheels. Now as more and more folks are riding big wheeled bikes, the ...read more
