The Surly Hurdy Gurdy is a chain tensioner built for the Surly Cross-Check's semi-horizontal front-loading dropouts and will also work on many other similar dropouts. Being an investment cast of stainless steel makes it both a good looking and durable device for keeping your rear wheel from slipping forward while under load. The Hurdy Gurdy works with QR's, bolted axles and nutted axles up to 10mm.
Fits most forward loading dropouts
