Surly Hurdy Gurdy Chain Tensioner. Hurdy Gurdy is another nifty device that keeps a rear wheel from slipping forward in the dropout under pedal load. Designed for Surly Cross-Check’s semi-horizontal front-loading dropouts, and will also work on many other similar dropouts. Investment cast of stainless steel for durability and good looks.
