The correct spacer thickness depends entirely on the gap between your cassette and the shoulder of your freehub body once the cassette is seated, so it must be measured on your own hub rather than assumed from the bike model alone. Always check the gap with a caliper or by test-fitting before locking the cassette down, since even a small mismatch in spacer thickness will throw off chainline and shifting precision.

Using a spacer that is too thin can leave the cassette lockring unable to fully thread down, risking a loose cassette that shifts on the freehub under load, while a spacer that is too thick can push the cassette outward enough to worsen chainline or cause chain rub on the front derailleur cage. Getting this dimension right is worth the extra few minutes of measuring, since it directly affects shifting quality and how safely the cassette stays seated.

Yes, these spacers can be combined, for example a 1.0mm and a 1.5mm together give 2.5mm, which is useful when your measured gap does not match a single available thickness exactly. Just make sure the total stack still allows the cassette lockring to fully engage the freehub threads once tightened.

These are generic flat spacers designed to fit standard splined freehub bodies used across most Shimano HG-compatible and comparable SRAM setups sold in India. They are not intended for proprietary micro-spline or XDR driver bodies unless the gap and spline profile have been confirmed to match, so it is best to verify your freehub type before ordering.

Yes, each FreeHub Spacer is machined to a consistent thickness from corrosion-resistant metal, built to handle the repeated load and torque of cassette lockring tightening without deforming. DoGoodCo sources these as genuine LeBycle components, so thickness and fit stay consistent every time you reorder.
