Compatibility & Buyer Notes
Please review the following before purchasing to ensure correct fitment.
TT / Triathlon Bikes Only
Designed specifically for TT and triathlon bikes with aerobar extensions. The SW-TT7110 mounts at the aerobar tip (Φ19.5mm); the BL-TT7110 mounts on the base bar (Φ21mm). Not intended for drop-bar road bikes — use EDS TX for those.
Verify Aerobar Tip & Base Bar Diameters
SW-TT7110 requires aerobar inner diameter of Φ19.5±0.5mm. BL-TT7110 requires base bar diameter of Φ21±0.5mm. Confirm your cockpit dimensions before ordering.
Confirm Cassette & Caliper Mount Type
Rear derailleur supports max sprocket 30-36T across 3-14 speed cassettes. Confirm your cassette falls within this range. Also confirm your frame and fork's disc brake caliper mount type and rotor size before ordering.
App Pairing Required Before First Ride
After installation, pair all components to the WHEELTOP app over BLE, assign button functions, and run gear calibration. The app is free on iOS and Android.

What cassette speeds and chain brands are compatible with the WHEELTOP EDS-TT?
The WHEELTOP EDS-TT works with 11-speed cassettes from Shimano, SRAM, and other standard road brands, and is compatible with all standard chain types including Shimano, SRAM, and KMC chains. The carbon fiber OSPW cage is specifically engineered for 11-speed drivetrains common on triathlon and time trial bikes, ensuring precise shifting across your entire cassette.
How difficult is it to install the WHEELTOP EDS-TT, and what tools do I need?
Installation is straightforward for experienced mechanics and typically takes 30-45 minutes, requiring only basic tools like hex keys, screwdrivers, and a chain tool—no cable routing needed since the WHEELTOP EDS-TT eliminates shift cables entirely. You'll need to remove your existing derailleur and replace it with the electronic unit, then calibrate via the WHEELTOP app before your first ride.
How long does the battery last, and how do I charge the WHEELTOP EDS-TT?
The WHEELTOP EDS battery delivers approximately **24,000 shifts per charge** (~60+ hours of typical riding). Battery level is monitored in real-time via the WHEELTOP Bluetooth app. Charging uses the proprietary **magnetic charging cable** (not USB-C) — attach it to the magnetic port on the derailleur and a full charge takes about 2 hours. The EDS OX2.0 also features a **user-replaceable battery** (remove 4 screws with a 2mm hex key to swap).
How do I pair and calibrate the WHEELTOP EDS-TT with my bike and race head unit?
Download the WHEELTOP app on iOS or Android, follow the Bluetooth Low Energy (BLE) pairing process, and run the automatic calibration routine which takes under 2 minutes and ensures perfect indexing across all 11 gears. The WHEELTOP EDS-TT also supports ANT+ connectivity for direct integration with Garmin, Wahoo, and other popular race computers, and firmware updates are pushed automatically through the app.
How does the WHEELTOP EDS-TT compare in price and features to Shimano Di2 or SRAM AXS?
At ~$759, the WHEELTOP EDS-TT undercuts both Shimano Di2 (~$1,200+) and SRAM AXS (~$1,100+) while delivering 4 fully programmable buttons instead of limited shifter options, plus a hollow oversized carbon fiber pulley cage that reduces weight and improves aerodynamics for triathlon-specific performance. You get zero cables through your frame like premium groupsets, but at a significantly lower price point without compromising on ANT+ and BLE connectivity for race integration.
Is the WHEELTOP EDS-TT waterproof, and will it hold up in rain and wet conditions?
The WHEELTOP EDS-TT features sealed electronics and weatherproof connectors rated for triathlon conditions including rain, spray, and pool water exposure, making it suitable for both open-water swimming transitions and wet-weather training. The carbon fiber OSPW cage is corrosion-resistant and the derailleur's compact sealed design protects internal components, though we recommend rinsing with fresh water after saltwater exposure to maximize component longevity.
Where can I buy the WHEELTOP EDS-TT, and what warranty coverage is included?
