Surly Singleator

Surly Singleator

Midwest single-speed legend Pete Geigle developed the 1x1 Singleator so you single-speed virgins could taste the pure mountain biking experience without spending too much cash. Installing horizontal dropouts on your frame can be difficult and/or expensive, particularly if your steed is of the aluminum variety. The Singleator mounts right up to your derailleur hanger and provides a
simple, effective, and adjustable means of tensioning the excess chain slack found in vertical dropout single-speed drive trains.

The Singleator features a triple sealed spring, larger cog capacity, chain guides, fully adjustable chain line, _floating pulley, and a stainless steel pivot bushing. We've made some improvements over our original Singleator, too: the main body is forged, so it's stronger. We've gone with an 11 tooth pulley for smooth, quiet operation. And, it now works with both 1/8" (BMX) and 3/32" (geared bikes) chains. Beware imposters; the Singleator is the granddaddy and outperforms all others.
