Gevenalle's HOUP (Halo Of Ultimate Protection) turns your road cassette into a cyclocross cassette in one fell swoop. By removing the smallest cog on your cassette (you probably don't use it in races anyway) and placing the precision-machined spacer behind the largest cog, you can tighten up your shifting and keep your chain from gouging your spokes if and when the chain drops off the largest cog toward the inside. It makes your cassette lighter and more resilient while giving your peace of mind during races.
If you want to go one step further in lightening the cassette, choose the titanium upgrade option, which includes the spacer, lockring, and a three-cog spider featuring titanium cogs to replace the largest three cogs in your cassette.
