The Absolute Black 28 - 40 cassette adapter is a perfect upgrade option for those looking to get a little more out of their low end during those intense, sustained ascents. Designed to work with either Shimano or Sram type 10 speed cassettes, the Absolute Black cassette adapter is constructed from anodized 7075 Txxx aluminum alloy to produce a simultaneously stiff and lightweight product. The cassette adapter consists of a 28 - 32 - 36 - 40 tooth pattern that is designed to replace your current 28 - 32 - 36 tooth cluster and give you that extra push uphill. By removing the 11 tooth (Shimano type) or 15/17 tooth cog (Sram type) along with the last 3 cog cluster, one is able to install the Absolute Black system seamlessly. By removing the heavier OEM cog and cluster, and replacing them with the 28 - 40 cassette adapter, each rider will drop an average of 50 grams from their cassette (a sizable difference).
