WHEELTOP EDS TT Wireless Electronic Groupset Triathlon & Time Trial Bike Shiftin


Wireless Electronic Groupset · Triathlon & Time Trial

WHEELTOP EDS TT

A fully wireless electronic groupset purpose-built for triathlon and time trial bikes. Shift from the aerobar tips without breaking position — bar-end shifters at the end of your aerobars, plus two additional shift buttons on the base bar brake levers, give you six programmable buttons across both cockpit positions. The rear derailleur runs carbon fiber hollow oversized pulleys for reduced drivetrain friction. Hydraulic disc brakes, IP67 sealing, BLE/ANT+ connectivity, and full WHEELTOP app control round out the system.

Aerobar Control

SW-TT7110 Bar-End Shifters — Shift Without Breaking Aero

Wheeltop SW-TT7110 bar-end aerobar shifters

Four Buttons. Zero Compromise to Aero Position.

The SW-TT7110 mounts at the tip of each aerobar extension. Four angled, thumb-reach shift buttons let you shift front and rear derailleurs without lifting your torso, moving your elbows, or changing position in any way. The serrated shark-fin profile is sculpted from biomimetic aerodynamic principles — form and function engineered together to cut through the air rather than fight it.

Four Programmable Buttons

All four buttons on the SW-TT7110 are programmable via the WHEELTOP app — assign front shift up/down, rear shift up/down, or custom functions. The system's flexibility expands what a shifter can do beyond just gear changes.

Base Bar Control

BL-TT7110 Base Bar Brake Levers — Shift from the Hoods Too

Two additional shift buttons on the base bar levers complete the six-button cockpit — full gear control in both riding positions.

Brake and Shift from the Base Bar

The BL-TT7110 levers clamp to your base bar and combine hydraulic braking with two integrated shift buttons — so when you sit up in transition, sprint through a finish, or handle technical corners, you always have shifting right at your fingers. Left and right levers are interchangeable so you can configure your cockpit exactly as you prefer. Reach is adjustable from 70mm to 100mm to suit any hand size. The carbon fiber and aluminum construction keeps weight low without sacrificing brake lever rigidity.

Left / Right Interchangeable

Both levers share the same design and can be swapped sides — configure your brake and shift assignments freely without being locked to a fixed left/right layout.

Rear Drivetrain

Electronic Rear Derailleur — Carbon Fiber Oversized Pulley Cage Upgraded

The EDS TT rear derailleur runs the same 800mAh electronic platform as the TX, upgraded with carbon fiber hollow oversized pulley wheels for lower drivetrain friction and higher power transfer efficiency.

Wheeltop EDS TT rear derailleur with carbon fiber oversized pulley wheels

Carbon Fiber Hollow Oversized Pulley Cage

Oversized pulley wheel systems reduce the chain's wrap angle around each pulley, which means less chain articulation per revolution and measurably lower friction across the full drivetrain. The TT rear derailleur upgrades to carbon fiber hollow oversized pulleys — lighter than standard, stiffer under load, and noticeably smoother under hard pedaling effort. On a TT bike where every watt counts, this is exactly where gains matter most.

Dual-Input Shifting

The rear derailleur accepts shift commands simultaneously from both the aerobar bar-end shifters and the base bar brake levers — you can shift from either position with no lag, no priority conflict, and no reconfiguration required.

Front Shift on a Button Press

The EDS TT front derailleur runs its own built-in 500mAh rechargeable battery via Pogopin magnetic charging, and shares the same BLE/ANT+ wireless system as every other component in the kit. Compatible with 53T chainrings standard on TT and triathlon bikes. Like the rear, it accepts commands from both cockpit positions simultaneously — aerobar tips or base bar, whichever you reach for first.

Wheeltop EDS TT hydraulic disc brake caliper — CNC unibody, ceramic pistons

CNC Unibody. Shark-Fin Heat Sinks. Ceramic Pistons.

CNC-machined from a single aluminum alloy block for maximum rigidity. Shark-fin heat sinks increase surface area and dissipate heat faster to delay thermal fade on long descents. Full ceramic pistons resist high heat and maintain consistent bite point through sustained braking. A unidirectional oil circuit prevents fluid backflow and sharpens brake response speed.

Before You Order

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?

The WHEELTOP EDS-TT is available exclusively through Aoeagle's eBay store with worldwide shipping and a full manufacturer's warranty covering defects and electronic components.
