Cyclocross Cassettes

Our cyclocross cassette system is easily the least expensive and most effective method to provide extra protection to your drivetrain from the mud.  We simply allow you to remove the 11T cog from your cassette (you really don’t need it unless you are running a 1X) and replace it with a custom machined spacer behind your largest cog.  The result is a more resilient, lighter, less complicated setup with extra space between your derailleur and spokes and also room for your chain to drop without gouging your spokes should it come off.

Basically, less days like this: View Photos of Derailleur Failures

Custom machined cassette spacers designed specifically for purpose. 10 and 11 speed versions available.
10 Speed Version compatible with Shimano 5700 and 6700 Cassettes.
11 Speed version compatible with Shimano 5800 and 6800 Cassettes.
Includes aluminum lockring to accommodate either 12T or 13T.
Titanium options includes replacement 3 ring spider with titanium cogs: 10 Speed – 21-24-27T, 11 Speed – 23-25-28

Titanium Upgrade Option

HOUP‘s are super affordable (we think the best $20 you can spend on your cyclocross bike) but if you want to go a little further with your bike spec then drop some weight from your cassette with one of our titanium 3-ring replacement cog sets.  Simply install in place of existing cogs for a fraction of the cost of a top level Dura-ace model for most all the weight savings.


Simply place HOUP behind existing cassette. Remove existing lock ring and 11T cog and then secure cassette with provided alloy 12/13T lockring. Adjust derailleur limit screw to ensure chain now only moves as far as needed to reach lowest gear.https://vimeo.com/94598776
