Cassette Spacers

4.5 mm spacer to fit a 7-speed cassette onto a hub made for 8-, 9-, or 10-speed cassettes. If your cassette has bolts holding the sprockets together, you will need to remove the bolts. They are not necesssary, only intended as a convenience for rapid cassette swaps.

Individual Shimano sprockets for Shimano cassettes. 7, 8 or 9 speed compatible. The differences in thickness between 7-, 8- & 9-speed sprockets that don't have built-in spacers are so small that substituting 2 or 3 in a cassette won't have any affect on the indexing. If you don't find the Shimano cogs you want here, check the QBP pages for Miche Shimano compatible cogs: These cogs, made by Miche in Italy, are very high quality and work exactly the same as Shimano's cogs. They are available in more sizes than Shimano's. They are also available for Campagnolo cassettes.

Note: This version features two conical spacers that will keep cog more rigid. Place cog between the flared ends of conical spacers. Converts a Shimano 7, 8 , or 9 speed freehub for use as a single speed. This set of spacers allows the single speed sprocket to be easily aligned with the correct chainring.
