Schlumpf 34T/68 High Speed Drive w/170mm Cranks - The Schlumpf High Speed Drive is our favorite piece of cycling engineering. This planetary gear setup will give you higher high gears and lower low gears. If you have a trike with a 20in rear wheel the HSD will give you back the high end you are missing.
Rohloff Drivetrain Wheel with OEM2 Tensioner Chain - The Rohloff 14-speed transmission is the ultimate in internal gearing. All gears are evenly spaced and can be shifted while pedaling or standing still. Low maintenance and reliability is the name of the game here.
Avid BB7 Front Disc Brake Kit (pair) - This kit includes everything you need to upgrade your trike's brake system to the best mechanical disc brake system available. Perfect for for any home builds.
