SRAM first introduced their 10-speed road cassettes using the OpenGlide design which had a section of each cog missing for easier transitions from gear to gear. Some felt that this caused the chain to catch and actually negatively affected shifting. Others love it and feel it is an improvement.
Now SRAM gives you a choice by making a 10-speed cassette with their more traditional Powerglide tooth profile. Heat-treated steel cogs for long life. Last three cogs are on an alloy carrier and have holes at each tooth to save weight. 7000 series alloy lockring included. Compatible with SRAM/Shimano 8/9/10 freehub bodies (NOT compatible with Shimano 10-only freehub bodies). Compatible with SRAM or Shimano 10-speed chains.
To keep your drivetrain shifting properly when you change your cassette or chainrings, you should also replace your chain. Take a look at our selection of 10 speed chains here.
I replaced my high end SRAM 1099 XX Cassette with this 1070 and even though it's not as light, it is a great value and it's very durable. The 1070 cassette allows for accurate shifts and it's very easy to clean. I'm very pleased with it overall.
