Best High-End
Best Mid-Range
Best Inexpensive

We spent 23 hours on research, videography, and editing, to review the top picks for this wiki. Rear derailleurs are just one component of a bike's groupset, but they make a huge difference in how smoothly and easily your two-wheel ride changes gears, especially when doing so while accelerating or under load. A perfectly engineered model responds immediately as soon as you press on your shifter and can last though years of use without requiring constant tweaking. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best rear derailleur on Amazon.

Editor's Notes

November 25, 2018: While they may all look relatively similar to the novice, the engineering and construction quality of rear derailleurs can actually make a huge difference in how well your bike shifts between gears. We did our best to include models that function well in a variety of price ranges, as well as units designed for trail and road riding.

A wandering writer who spends as much time on the road as in front of a laptop screen, Brett can either be found hacking away furiously at the keyboard or, perhaps, enjoying a whiskey and coke on some exotic beach, sometimes both simultaneously, usually with a four-legged companion by his side. He has been a professional chef, a dog trainer, and a travel correspondent for a well-known Southeast Asian guidebook. He also holds a business degree and has spent more time than he cares to admit in boring office jobs. He has an odd obsession for playing with the latest gadgets and working on motorcycles and old Jeeps. His expertise, honed over years of experience, is in the areas of computers, electronics, travel gear, pet products, and kitchen, office and automotive equipment.
