Catrike Clamp-On Return Idler Kit
The Catrike Clamp-On Return Idler Kit comes with a return side idler (either Sport or Elite) and, like the power, a Clamp-On Idler Mount, all necessary chain keeper hardware needed to float a return idler anywhere on a Catrike that you'd like. Most people put their floating return idler just in front of the right side frame tube. Depending on boom position and chainring sizes, the idler can handle the chain going over or under. It can take some serious finagling to get just right, but for those people looking to eliminate chaintube, this kit can be a big help.
