Specifications
Full technical breakdown of the OX 2.0 wireless electronic rear derailleur.
Replaceable Derailleur Cage
The cage plate is secured by hex socket screws — swap it in minutes with a 3 mm hex key. Use a professional-grade precision hex key (RC / model aircraft type recommended) — a cheap or worn key will strip the small screws instantly. Change cage length, replace a damaged cage after a crash, or upgrade when new cage options become available.
Trail Crashworthy
Bent cage after a rock strike? Replace just the cage — not the whole derailleur. Far more cost-effective than replacing the entire unit.
Flexible Configuration
Switch between 58 mm (short), 75 mm (medium), and 93 mm (long) cages as your drivetrain changes — one derailleur body, multiple setups.
Which Cage Length is Right for You?
The OX 2.0 comes in three cage lengths, each engineered for a specific cassette range and riding style. Choosing the wrong cage will compromise shift quality and chain tension — confirm your largest sprocket before ordering.
Still not sure? Check your cassette's largest sprocket: up to 32T → Short · 34–42T → Medium · 46T and above → Long. When in doubt, send us a message before ordering — we're happy to help you pick the right one.

Compatibility & Buyer Notes
Please review the following before purchasing to ensure correct fitment.
Requires a WHEELTOP EDS OX 2.0 Shifter
This listing is for the rear derailleur only. You'll need a WHEELTOP EDS OX 2.0 wireless shifter to control it — buy ours separately, or use one you already own.
UDH Frames: Mounts on the Existing Hanger, No Extra Parts
This is a standard hanger-mount derailleur, not a hangerless direct-mount like SRAM Transmission — so if your frame uses a UDH hanger, leave it in place and bolt the derailleur straight onto it, no adapter needed. WHEELTOP lists UDH frames as "partially compatible" because on a small number of frames, the derailleur body can lightly interfere with the frame near the smallest cog. After installing the chain, shift to the smallest cog and check by hand for any rubbing before fine-tuning limits in the app.
1x Drivetrain Only
Designed for single-chainring setups. Not compatible with double or triple chainring systems due to direct-mount structure.
Choose the Right Cage Length
Verify cassette size before selecting cage version: 58mm (10-32T) · 75mm (10-42T) · 93mm (10-52T).
App-Based Setup Required
Initial calibration must be performed via the WHEELTOP app (free on iOS and Android) after installation.

Is the WHEELTOP EDS OX 2.0 compatible with my current drivetrain?
The WHEELTOP EDS OX 2.0 works with 11-speed and 12-speed cassettes—check our product page for exact compatibility with your specific cassette model. It's compatible with most modern MTB frames and works with SRAM, Shimano, and other chain brands, but verify your shifter type before purchasing since electronic derailleurs require compatible shifters.
How difficult is it to install the WHEELTOP EDS OX 2.0, and what tools do I need?
Installation is straightforward for anyone with basic bike maintenance experience and typically takes 30–60 minutes. You'll need a 2mm hex key, cable cutters, and a derailleur hanger alignment tool—most installation steps mirror mechanical derailleur setup, with the added step of connecting the wireless shifters and calibrating via the WHEELTOP app.
How long does the battery last, and how do I charge the WHEELTOP EDS OX 2.0?
The OX 2.0 battery delivers approximately 24,000 shifts per charge—roughly 60+ hours of typical riding. Charging uses a proprietary magnetic charging cable (not USB-C or micro-USB); simply attach the magnetic tip to the derailleur port for a full charge in about 2 hours, and the user-replaceable battery can be swapped by removing 4 screws with a 2mm hex key.
How do I pair and calibrate the WHEELTOP EDS OX 2.0 with my bike?
Download the WHEELTOP app on your smartphone and enable Bluetooth or ANT+ to pair the derailleur and shifters in minutes. The app walks you through automatic calibration, which ensures precise shifting, and you can also receive firmware updates through the app to keep your system running optimally.
How does the WHEELTOP EDS OX 2.0 compare to Shimano Di2 or SRAM AXS in terms of price and performance?
At approximately $237, the WHEELTOP EDS OX 2.0 offers significant savings compared to Shimano Di2 and SRAM AXS systems, which often exceed $400–600. You get dual-protocol connectivity (ANT+ and Bluetooth), compatibility with multiple app ecosystems (WHEELTOP, Garmin, Wahoo), and a user-replaceable battery—matching premium features at a fraction of the cost.
Is the WHEELTOP EDS OX 2.0 waterproof and suitable for all-weather riding?
Yes, the WHEELTOP EDS OX 2.0 carries an IP67 waterproof rating, meaning it's fully sealed against dust and can be submerged in up to 1 meter of water for 30 minutes. This makes it ideal for wet trails, creek crossings, and year-round MTB riding without worry about moisture damage to the electronics.
Where can I buy the WHEELTOP EDS OX 2.0, and what warranty coverage do I get?
The WHEELTOP EDS OX 2.0 is available on Aoeagle's eBay store with worldwide shipping and comes backed by a full manufacturer warranty for peace of mind. Visit Aoeagle on eBay today to secure your wireless electronic derailleur and transform your MTB shifting experience.
