SRAM PG-980 Cassette $0.00
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, which has eight of the nine the cogs on a single spider and the economical PG-970 and PG-950 which have all the cogs sliding on individually. As with all SRAM cogsets, the ramps built into the cogs are the reliable PowerGlide II design. There are two different ratios, 11/32 and 11/34. Weight 280g (11-32).
- Blasted, chrome plated steel construction is lightweight and extremely durable
- Aluminum spider with steel cogs for light weight and reliability
- Powerglide II technology uses an optimal tooth profile and shift ramp design to provide quick, precise shifting

Despite the photo this does indeed come with 9 rings.

Is this a full cassette? or is it just the top three gears as shown? Just wondering why this one looks different from all the other products.
Durable, Lightweight Cassette
I've had the 970 and I've used the 990. I think this is a worthwhile upgrade over the 970 weight-wise, as it replaces a bunch of the inner cogs with the aluminum holder. The 990 replaces more and saves a little more weight, but costs way more. I think this is the best value of the bunch, saves weight but is not ridiculously expensive (of course, if you don't care about weight, get the 970). All three have great wear lifetimes as all their cog teeth are steel.
