*SURLY* 1X1 singleator (silver)

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.
