Gates RDM Snubber incl. snubber screw
The Gates RDM Snubber, supplied with its snubber screw, keeps the Gates belt securely on the sprocket and prevents it from skipping. A skipping belt can damage the inner carbon cords, so a snubber protects the belt.
Why choose this tool?
Stops belt skipping. Keeps the belt on the sprocket and prevents tooth jump.
Protects the carbon cords. Skipping can damage the inner carbon structure, which can cause damage to the belt while riding.
Screw included. Supplied with the snubber screw for the rear derailleur mount.
For mud and snow. Gates notes that a snubber can eliminate tooth jump in muddy or snowy conditions.
How is a snubber set up?
A snubber is a component near the rear sprocket that eliminates tooth jump or belt derailment. Gates says it should sit about 1 mm from the back of the belt, cover the full width of the belt and not touch the belt while you ride.
Which snubber part do I need?
The RDM Snubber comes with its screw. If you only need the screw, see the Snubber Screw; for wider installation widths, 142 mm and more, see the Snubber Spacer Kit.

Frequently asked questions
Do I need a snubber?
Gates requires snubbers for certain full-suspension applications and says a snubber can also help against tooth jump in mud or snow. Ask us whether your bike needs one.
How far from the belt should it sit?
About 1 mm from the back of the belt, covering the full width of the belt, and it should not touch the belt in operation.
Do I need special tools for a belt drive?
A belt drive needs far less than a chain, but the right tension and alignment matter. Gates offers tools for checking tension, checking alignment, fitting sprockets and protecting the belt – see the table above, and ask us which ones suit your bike.
Why does sprocket alignment matter?
Front and rear sprockets must stay aligned within ±1.0 mm. Misalignment can cause tooth jump, faster wear, noise, belt derailment or belt failure.
