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

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.

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.

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.

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.

Per-Gear Fine Adjustment

Dial in every sprocket individually. If one gear feels off, adjust it directly in the app without touching the bike - a precision that cable systems simply can't match.
