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 drivetrains.The Singleator features a triple-sealed spring large cog capacity chain guides fully-adjustable chain line floating pulley and a stainless steel pivot bushing. The main body is forged so its strong. Surly has 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 impostors; the Singleator is the granddaddy and outperforms all others.Triple-sealed spring large cog capacity and chain guides Stainless steel pivot bushing Includes two springs for upward or downward tension adjustment Do not use with a coaster brake fixed gear multi-cog or multi ring drivetrains
