The RANS V3 and the Stratus XP have some of the straightest and most beautiful chain lines of all the RANS bikes. Our RANS V3/Stratus XP Idler Kit compliments this drive train by giving you a high quality T-Cycle Return Idler and Stainless Steel Chain Keeper. Installation is a breeze. The long life built into this kit ensures that your chainline will be optimized from the first ride to the last, as long as you have your bike.
I finally got rid of the big black donut and modernized to the TerraCycle idler on my Stratus XP. I am still in early season shape, so can't say much about the change in pedaling effort. However, the shifting seems more positive and there is less chain bounce with the idler.
