Derailleurs - rear

The most cost-effective way to upgrade your bike to electronic shifting in 2024

A well-priced and capable mech for mega-range setups, if missing a barrel adjuster and cage lock

Very expensive, very quiet, very controversial

Wireless shifting for (some of) the masses, in a very well executed, robust package with huge potential

Works really well off-road, though less useful on road, and the limited range will limit its appeal

Crisp shifting and bling looks, but plagued with setup issues

Quirky looking mech that shifts really sweetly - a shrewd option for budget builds and/or working bikes with wider gear ratios.

Superb aftermarket jockey wheels for top-flight rear mechs

Works well, looks good, but faces stiff competition as a Shimano alternative

The increased capacity and precise shifting make it hard to beat
