To connect, you need to tap the Bluetooth icon in the app. Before doing so, make sure the derailleur hasn't gone into sleep mode. If it has, just give the derailleur a tap or shake the bike to wake it up. Once the connection is successful, the Bluetooth icon will light up — and you're all set to start adjusting your derailleur.

For EDS TX series:

1. Set the front derailleur to the largest sprocket
2. Set the rear derailleur to the smallest cog position
3. Open the WHEELTOP App → Initial Calibration

Use "<" or ">" buttons to align the RD pulley with the smallest cog

Exit the initial calibration page

For EDS GeX and OX series: Same steps but skip step 1 (no FD adjustment required).

The EDS-OX2 supports 3 to 14-speed cassettes with sprockets up to 32T, making it versatile across most modern groupsets. It works with any standard bicycle chain, regardless of brand, since the derailleur uses electronic shifting rather than cable tension.

Installation is straightforward with the bolt-on mounting system compatible with most modern frames—typically requiring only a 4mm or 5mm hex wrench and 15-20 minutes. The WHEELTOP app provides step-by-step calibration guidance once mounted, eliminating complex barrel adjuster tuning.

The WHEELTOP EDS OX2.0 features an **800mAh replaceable battery** that delivers approximately **24,000 shifts per charge** — equivalent to 60+ hours of typical trail riding. Battery level is displayed in real-time via the WHEELTOP Bluetooth app. Charging uses the proprietary **magnetic charging port** (not USB-C); simply attach the magnetic cable and a full charge takes about 2 hours. Unlike Shimano Di2 or SRAM AXS, the OX2.0 battery is **user-replaceable** — remove 4 screws with a 2mm hex key to swap it out.

Pairing is simple: download the WHEELTOP app on iOS or Android, enable Bluetooth, and follow the in-app calibration wizard to sync your derailleur. The app enables over-the-air firmware updates, gear position tracking, and battery monitoring, all managed directly from your smartphone.

At approximately $339, the EDS-OX2 undercuts Di2 and AXS systems by $400-800 while offering wireless shifting without cables, Bluetooth app integration, and ANT+ compatibility with Garmin/Wahoo devices. While premium brands offer broader component integration, WHEELTOP's electronics deliver comparable shift speed and reliability at a fraction of the cost.

The aluminum alloy 58mm short cage derailleur is sealed against moisture and built to withstand harsh conditions comparable to cable-actuated systems. The wireless design eliminates cable corrosion, and the sealed electronic components maintain reliability in rain, mud, and snow—perform regular cleaning to extend service life.
