The Surly Singleator easily mounts to your derailleur hanger. It offers a straightforward, efficient, and adjustable way to tension the extra chain slack in vertical dropout single - speed drivetrains. This amazing device features a triple - sealed spring, high cog capacity, chain guides, a fully adjustable chain line, a floating pulley, and a stainless - steel pivot bushing. The forged main body ensures great strength. With an 11 - tooth pulley, it operates smoothly and quietly. It works with both 1/8' (BMX) and 3/32' (geared bikes) chains. Don't be fooled by imitators; the Singleator is the best in class and outperforms all others.

Using the Surly Singleator is a breeze. First, find the derailleur hanger on your bike and mount the Singleator right on it. It's designed to be easy to install and adjust, so you can quickly get the right tension for your chain. When you're out riding, make sure to keep an eye on the chain tension. If it seems too loose or too tight, you can easily adjust it using the adjustable features. For maintenance, it's a good idea to clean the Singleator regularly. Wipe off any dirt or grime that might have built up, especially around the chain guides and the pulley. Check the triple - sealed spring from time to time to make sure it's in good condition. And remember, only use it with 1/8' (BMX) or 3/32' (geared bikes) chains as other chain sizes might not work properly.
