SRAM PG-950 9 Speed Cassette 2014
Reliable and durable cassette technology. SRAM's cassette performance is optimized through tooth profile and shift ramp design for quick and positive index shifting.
I have used this cassette as well as the PG-970 and this cassette is a great cassette for the money. Compare this brand of cassette to any fair equal offered by Shimano and you'll most likely find equal or comparable performance for less money. Corrosion resistance is great, I've used this unit for winter riding, in the rain, mud, and gotten it wrapped up in weeds. This cassette has given respectable performance all around, and is a product I would continue to trust in the future.
