FAQs

What tools do I need for installation?

You will need a chain tool (to adjust chain length), a hex key or Allen wrench, and possibly a screwdriver to remove your existing gears.

Can I use this with any type of chain?

Is this compatible with bikes that have horizontal dropouts?

How do I determine the correct chain length?

Wrap the chain around the chainring and cog. Add two links, and then install it on the bike with the tensioner.

Does the STS come with any spacers?

The DMR STS is often available as a combo kit with the DMR Single Speed Spacer kit, but it depends on the purchase.

How do I maintain the pulley?

Clean the pulley regularly to remove dirt and debris. Lightly lubricate the bearings as needed to maintain smooth operation.

Where can I find more detailed instructions?

Troubleshooting

Chain is skipping or coming off.

Adjust the tension on the DMR STS to ensure the chain is properly aligned and taut. Check the chain length to ensure it's suitable for the single-speed setup.

Difficulty installing the STS.

Make sure the STS is correctly positioned within the vertical dropouts. Ensure the quick release is properly tightened.
