The Catrike Clamp-On Power Idler Kit has a power side idler (either Sport or Elite), a Clamp-On Idler Mount and the chain keeper hardware to let your idler float nicely along. We make this kit for riders who want to eliminate their power side chaintube. If you need another idler to either keep the power side chain from rubbing the top of the sideways frame tube or to reroute the chain under the frame, then this is for you. The mount can be flipped up or down and moved forward and backward as needed.
