The Schlumpf High Speed Drive 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. For more information on how the High Speed Drive works, go straight to the Schlumpf web site (http://www.haberstock-mobility.com). Compatible with all trikes we currently sell except the Tandem.

    I have a Rover model with a NuVinci hub in rear. I had added the Slump (high-speed-drive) in front. This gives me about any speed and ease of cranking from flat out to any kind of hill. I also installed the kick plates for easy shifting. It makes riding a pleasure and a joy.
