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.

Made for the Trail

The EVOSID MTB crankset is designed for trail, enduro, bike park and DH-style riding — steep technical sections, fast berms at your local park or laps of the pump track. The light crank arms take some of the sting out of hard, technical climbs, so you can ride more of the trail with less effort.

DUB 29mm Spindle

A stout 29mm DUB-standard spindle, forged from AL-7075 aluminum alloy and 130mm long, keeps the crankset solid over rough, demanding terrain.

Hollowed-Out Chainring

The chainring is fully CNC-machined from 7075 aluminum alloy with a cut-out spoke design that removes weight while keeping the ring stiff and stable under load.

3-Bolt Direct Mount, Boost Chainline

The chainring mounts directly to the crank arm with 3 T25 bolts (9 N·m) in the SRAM 3-bolt direct-mount pattern, so swapping rings is quick and simple. The 3mm offset gives a 52mm Boost chainline, the standard on modern Boost mountain bikes.

Lightweight Without Giving Up Strength

Both the crank arms and the chainring use a hollowed-out design — material comes out where it isn't carrying load, cutting weight while keeping the strength where it matters.

Narrow-Wide Teeth Keep the Chain On

Alternating narrow and wide teeth match the chain's inner and outer links. The tight fit between chain and ring keeps the chain from dropping and cuts down the chatter that rough ground and shifting can cause.

Threaded Bottom Bracket, Cups Included

The crankset ships with its matching EVOSID BC1.37"×24T (BSA/English threaded) bottom bracket. Overall width is 90mm and it accepts bottom bracket shells from 68mm up to 73mm wide, with included spacers (two 2.6mm gaskets, a 3mm spacer, and a 4.5mm spacer) to take up the difference. Threading directly into a standard threaded shell also avoids the creaking that press-fit bottom brackets are known for.

Is Your Frame Compatible?

As long as your frame's bottom bracket shell is BSA (English thread) between 68mm and 73mm wide, this bottom bracket installs without any issue. It is not a press-fit design.

Fully Hollow Plates. Flat-Top Profile.

The CHOHO Z12-DSL is a dedicated 12-speed chain with fully hollowed-out plates and a flat-top profile, cutting weight without giving up strength. The inner and outer plates are chrome-treated for wear resistance and finished in silver, and the chain comes pre-lubricated with FUCHS grease. Supplied at 128 links, the extra length a 50T cog needs — trim to fit your frame during installation.

11-50T Wide Range on an HG Driver

Twelve cogs from 11T to 50T give an easy climbing gear and a fast top gear on a single chainring, and the whole cassette drops onto a standard Shimano HG freehub body — no special driver needed.

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.
