Description
 
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.schlumpf.ch/).

Compatible with all trikes we currently sell except the Tandem.

Super Addition! September 15, 2018
Reviewer: Stephan Ripsom from Fisher, IL United States  
I added a Schlumpf to my Rover and noticed an immediate over all improvement! New lower ratios make climbing hills so much easier! Higher ratios give speeds unknown before! Same speed as being in the highest gear, but still had 4 gears left. Almost scary speed.
From 8 to 16 speeds in one swoop!
Well worth it!

High Speed Drive September 28, 2015
Reviewer: Ron from , Burlington, IA.  
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.
