TerraTrike High Speed Drive

The Schlumpf High Speed Drive is on the right side of the picture. It is the model of elegant simplicity. The High Speed Drive eliminates the front derailleur and the double chain ring. Each gear is evenly stepped(no overlapping or redundant gears). It has a single chain ring (27 tooth) with an internal gear. You cannot add additional chainrings to this product. The High Speed Drive has a standard gear that is a 1:1 ratio and an "overdrive" gear that features a 2.5:1 gear ratio. Click on the gear range link for a handy comparison chart.
