WHEELTOP EDS TX RA7000 V2 GROUPSET
The WheelTop EDS TX RA7000 V2 wireless groupset represents a massive tech boom alternative for road and gravel riders seeking electronic shifting without the premium price tag. By eliminating frame cables entirely, this kit offers a clean, minimalist cockpit and incredibly straightforward installation. Both the ergonomic, low-profile shifters and the rear derailleur cage are crafted from high-grade carbon fibre, cutting dry weight down to a highly competitive 1,190 grams—making it comparable to top-tier flagship systems from traditional manufacturers.
The standout feature of the EDS TX platform is its unprecedented drivetrain versatility. Using the dedicated WheelTop mobile app, riders can calibrate the rear derailleur to precisely match the spacing of any cassette from 7-speed up to a massive 14-speed configuration. This future-proof adaptability means you can seamlessly upgrade your mechanical bike to electronic wireless shifting while retaining your current wheels, cassette, chain, and crankset.
Braking is equally advanced, utilising a bilateral hydraulic disc brake architecture paired with one-piece CNC machined calipers.These calipers feature integrated ceramic pistons for superior heat resistance and come equipped with cooling fin brake pads to deliver powerful, progressive stopping modulation during technical descents.Backed by sealed, high-capacity internal batteries on each derailleur, the system provides up to 20,000 precise shifts on a single charge.
Key Features
7-to-14 Speed Universal App Customisation: A completely modular wireless system that allows the rear derailleur to adapt to any cassette spacing between 7 and 14 speeds via smartphone Bluetooth calibration.
Lightweight Carbon Fibre Architecture: Shifter lever blades and the rear derailleur pulley cage are built from carbon fibre to keep the system weight down to a race-ready 1,190g (dry).
High-Clarity Hydraulic Ceramic Calipers: One-piece CNC machined flat-mount calipers feature ceramic pistons and cooling fins for premium heat dissipation and fading resistance.

Why This IS For You
✅ Unbeatable Electronic Value: Perfect if you want to experience the modern luxury of wireless electronic shifting and hydraulic disc braking at a fraction of the cost of major brands.
✅ Ultimate Mixing and Matching: Ideal for custom builders who want to keep their favourite custom wheels, chains, or cassettes, thanks to the app-adjustable speed increments.
✅ Clean Cockpit, Easy Install: Excellent if you hate routing internal cables through bars and frames; the wireless derailleurs mount and sync in minutes.
Why This May NOT Be For You
❌ Non-Removable Derailleur Batteries: Unlike some competitors with hot-swappable batteries, the internal cells are permanently housed in the mechs and must be charged via a magnetic cable directly on the bike.
❌ Slight Panning/App Learning Curve: Initial setup requires using a smartphone app to micro-adjust alignment, which may feel overly tech-heavy for traditional home mechanics.
❌ Cassette Size Limitations: The rear derailleur maxes out at a 36T sprocket, meaning it is not natively suited for extreme 1x wide-range mountain bike or ultra-low gravel cassettes without a cage modification.
BFC PRO TIP
Because the WheelTop EDS TX V2 handles shifts digitally, the initial alignment is everything. When setting it up via the app, use the "calibration mode" to make tiny micro-adjustments until the chain sits dead-centre on your middle sprocket. Once that baseline index is locked in, the app's software automatically scales the spacing perfectly across the rest of your cassette. Also, when washing your bike, make sure the magnetic charging port rubber covers on the derailleurs are firmly pressed down to maintain that reliable IP67 weather seal!
