WHEELTOP EDS TX vs OX 2.0: Which Wireless Derailleur Should You Buy?

Quick answer: choose TX for a drop-bar road bike with two chainrings (2x, 7–14 speed, up to 36T). Choose OX 2.0 for a flat-bar mountain bike with one chainring (1x, 3–14 speed, cassettes up to 52T with the 93mm cage).

Why Cage Length Matters

A longer cage takes up more chain slack, which wide-range cassettes need. That's why OX 2.0 comes in three cage lengths.
