Built for the Seavo, the RANS Seavo Front + Rear Idler Kit is specifically designed to give your tandem a boost in performance and efficiency. Right off the bat, you'll notice the quieter ride. All too common chain derailments that occur with the stock idler package are a thing of the past! With two Power Idlers, a Return Idler and all the necessary hardware, this kit is the real deal for chainline maintenance. The Seavo is a great bike that deserves an equally great idler kit, we know if you make the upgrade you will feel the same way!
