Surly Hurdy Gurdy Chain Tensioner

Hurdy Gurdy is a nifty device that keeps your rear wheel from slipping forward in the dropout under pedal load. It’s designed for semi-horizontal front-loading dropouts (*ahem* like those found on the Cross-Check), and will also work on many similar dropouts.

Hurdy Gurdy is investment cast of stainless steel for durability. Its two axle holes allow for a wide variety of fore/aft wheel positions. It will work with standard QRs, bolted axles, and nutted axles up to 10mm.

Specifications: 

• Compatibility: Cross Check, Wednesday, ECR 29+, ECR 27.5 +, Ogre, Krampus, Karate Monkey SS & 27.5
