New OX2.0 Electronic Rear Derailleur

Equipped with a high-capacity integrated battery, the OX2.0 delivers exceptional endurance - capable of executing up to 24,000 gear shifts on a single charge. The magnetic snap-on charging connector makes top-ups effortless. A windowed protective cover shields the motor from all angles, while the IP67-rated sealed housing keeps dirt and water out, ride after ride.

Adjustable Chain Stabilizer

A precision-tensioned chain stabilizer suppresses chain slap and prevents dropped chains on rough terrain. The full aluminum alloy construction keeps the body rigid under load - reliable whether you're cruising fire roads or hammering technical singletrack.

Button-Style Shifter

Clean, minimal design with a satisfying mechanical-keyboard-style click. Shift up or down instantly - the derailleur responds with zero perceptible delay. IP67-rated dust and water resistance means it handles rain rides and post-ride washdowns without a second thought.

CR2032 Battery — Replaced in Seconds, No Tools Required.

The battery compartment cover sits on the back of the shifter body. To swap a cell, simply take a fresh CR2032, press it flat against the cover, and rotate — the cap threads off cleanly with nothing but finger pressure. No screwdriver, no coin, no dedicated tool. Drop in the new cell, twist the cover back on, and the shifter responds immediately. Standard CR2032 cells are available at any supermarket, gas station, or electronics shop worldwide.

The New Battery Is the Only Tool You Need.

No coin slot, no Phillips head, no prying. Press the fresh CR2032 flat against the cap and twist — it comes off with finger pressure alone. Your replacement part doubles as the removal tool.

Pair Your Components

Two Components, One Clean View

Just the rear derailleur and the shifter — no front derailleur or second lever to manage. Both show live charge level on the same home screen before every ride.

Set Your Cassette Speed

Not Locked to One Speed Count

Unlike a mechanical derailleur built for one fixed speed, EDS OX2.0 is fully configurable — set whatever speed count you're running, from 3-speed to 14-speed, directly in the app.

Run Initial Calibration

Guided On-Screen Alignment

No guesswork — use the on-screen +R / −L controls to nudge the guide pulley until it sits precisely under the smallest sprocket, then tap Finish.

Fine-Tune and Customize Your Shifter

Set It Once, Ride Your Way

Reassign the shifter's upshift and downshift buttons to trigger whichever function feels natural, or tap Factory restore to reset instantly.

Live Stats While You Ride

Tap GO in the bottom bar to switch into the ride screen, where elapsed time, calories, pace, average heart rate, cumulative shifts, and climb update in real time alongside turn-by-turn map navigation.

BR-MA3000 Caliper — 4-Piston, Dual-Side Braking

CNC-machined from a single billet of 6061 aluminum alloy, the BR-MA3000 caliper drives four opposed pistons — two per side — for strong, even clamping force. Integrated cooling fins pull heat away from the pads on long descents, keeping braking consistent instead of fading. Runs on mineral oil and is compatible with 140/160/180/203mm rotors from 1.8mm to 2.2mm thick.

Tested to 120°C / -20°C, 100,000 Cycles

Each caliper passes fatigue testing across temperature extremes and 100,000 braking cycles before it ships — built to hold up through summer heat and winter cold alike.

BL-MA3000 Lever — Left/Right Interchangeable

A vertical reservoir design routes the hose internally for a clean cockpit and compact footprint on the bar. The 2-finger lever body and bearing-connected pivot give a smooth, consistent pull. Both levers in the kit are identical — mount either one on the left or right, whichever suits your setup.
