One Build. Carbon Throughout.

Carbon fiber lever body with hydraulic disc brake calipers included — full ceramic pistons, CNC unibody construction. 2X configuration — front and rear derailleur both included. Best all-round build for disc-mount road and gravel frames.

EDS TX Electronic Rear Derailleur

Driven by a built-in 800mAh rechargeable battery at 8.4V, the EDS TX rear derailleur shifts instantly on a button press — zero cable lag, zero stretch over time. The exact speed count is configured through the WHEELTOP app — supports cassettes up to 36T. This build's derailleur cage is carbon fiber as standard, running a 12-tooth positive/negative tooth profile pulley wheel for quieter, more secure chain engagement. Charges through a magnetic Pogopin connector — snap it on, no port covers, no corrosion.

7-14 Speed, Set in the App

Unlike mechanical derailleurs locked to a fixed speed count, the EDS TX lets you define your speed range and per-gear position through the WHEELTOP app.

Precise Front Shifting on Demand

The EDS TX front derailleur runs on its own built-in 600mAh rechargeable battery and shares the same 8.4V system, magnetic Pogopin charging, and BLE/ANT+ wireless link as the rear unit. Pair both derailleurs to the WHEELTOP app for synchronized setup, gear mapping, and live status — front and rear shift in concert with a single button press from the lever.

Shift with a Button. Brake with the Lever.

A press of the shift button sends the command wirelessly straight to the derailleur — no cable pull, no mechanical play to wear in. Each lever runs on a single CR2032 button battery, swappable in seconds without tools. This build's lever bodies are carbon fiber as standard.

Carbon Fiber Body — Light, Stiff, Precise.

The carbon fiber lever bodies on this build are high-grade cold-laminated carbon fiber — visibly lighter and stiffer than an aluminum equivalent. The woven surface texture holds grip through wet descents without repositioning. The shift button sits exactly at thumb reach: index finger pulls the brake lever, thumb taps the shift button — no hand movement required.

One Lever, Two Functions.

Brake and shift from the same contact point. The lever body handles the brake pull, the button handles the gear command — both without taking your fingers off the bar.

CR2032 — One Battery. Years of Shifts.

Each shift lever runs on a standard CR2032 button cell. Open the battery compartment, drop in a fresh cell, and you're done — no charging cables, no tools, no downtime. A single CR2032 typically lasts well over a year of regular riding.

Available Everywhere

CR2032 cells are sold at any supermarket, petrol station, or electronics shop worldwide. If it runs low on a trip, a replacement is never more than a few minutes away.

CNC Unibody. Built to Run Cool.

The caliper body is CNC-machined from aluminum alloy as a single unit, ensuring rigidity and long-term safety under hard braking. Shark-fin heat sinks on the caliper body increase surface area for better heat dissipation, slowing down thermal fade on long descents. A unidirectional oil circuit prevents brake fluid from flowing backward, keeping lever feel sharp and response quick.

Full Ceramic Pistons

Full ceramic pistons resist high heat and hold a consistent bite point ride after ride — no fade, no spongy lever after a long climb or fast descent.

Flat or Post Mount. Pre-Bled. Ready to Ride.

Hoses are pre-cut and pre-bled from the factory. Unbox, install, ride. The mineral oil system is non-corrosive and easy to maintain at home. Confirm your frame and fork's caliper mount type (flat or post) and rotor size before ordering.

Per-Gear Fine Adjustment

Dial in every sprocket individually. If one gear feels off, adjust it directly in the app without touching the bike - a precision that cable systems simply can't match.
