DropGrip: Gripshift mod for dropbar road bikes

thingiverse

This project aims to integrate mountain bike-style gripshifts and a derailleur with road bike drop bars, creating a hybrid setup for a more ergonomic and reliable shifting experience. The author has chosen MicroShift R9 levers due to their good performance but acknowledges that they require regular tweaking when used with mountain gears. The components required include: * Straight mountain bike barends * Road bike lever ring clamps * M5x80mm bolt * Gripshifts appropriate for the gearing (e.g., 1x9, 3x7 single overlap, or 3x10 single overlap) * Barend track/tt bike brake levers * A 3D printer or lathe/CNC to create the barend insert The method involves cutting down the mountain bike bar ends to fit the gripshifts and road bike ring clamps. The author provides detailed instructions for assembling the system, including slipping the gripshift onto the barend, inserting the long bolt through the assembly, and tightening it until the barend is secure in place. Optional modifications include adding drop adapters to the flatbar for a flatbar breaking position or using inline levers for more flexibility. The project's goal is to create a hybrid system that combines the best of both worlds for riders who prefer drop bars but also want the robustness of mountain bike gearing.
