The SRAM PG 1070 cassette is available in a wide selection of ratios. It works with any Shimano 8, 9 or 10 speed compatible hub and is compatible with any 10-speed chain. PowerGlide technology allows for smooth gear transition either up or down shifting. The PG-1070 cassette features a semi-spidered design that is light, strong, and efficient. It only weighs 220 grams, but is made with heat-treated steel for a long service life. Now available in 11-32
Please note: does not work on Shimano 10-speed only rear hubs like 7800, and some Dura-Ace and Ultegra rear wheels
Can you please post which cassettes are compatible with a given cage length (short, med, or long)? I have a short cage rival and I'd like to know if the 12-28 cassette is compatible.
