The Force 5 has one of the cleanest, straightest chain lines around which is not an easy thing to do in the recumbent world. The power side idler is a great addition to this quality bike to ensure that your drive train remains quiet, smooth and worry free for the life of your bike. The Rans Force 5 solutions kit includes a famous TerraCycle power side idler, replacement socket head cap screw with an innovative, beautifully machined clamp on chain keeper in polished aluminum. All the required hardware is included as well as full instructions to make installation easy. One of the few bike specific kits where we say that the Aluminum cog really doesn't wear that fast, but if you must have Titanium, well that upgrade for just $20 more is available also.
