A Verified Combination, Not Just Parts in a Box
This isn't a random parts bundle — Aoeagle built this exact combination onto a complete bike and put it through rigorous testing to confirm smooth, precise shifting between these components and the WHEELTOP EDS TX before offering it as a set.
What's Inside the Kit
Electronic Rear Derailleur — 11-Speed
EDS TX Electronic Rear Derailleur
Driven by a built-in 800mAh rechargeable battery at 8.4V, the EDS TX rear derailleur shifts instantly on a button press — zero cable lag, zero stretch over time. Speed count is set entirely through the WHEELTOP app, so it's ready to match the 11-speed cassette included in this bundle. The standard pulley wheel uses a 12-tooth positive/negative tooth profile for quieter, more secure chain engagement. Charges through a magnetic Pogopin connector — snap it on, no port covers, no corrosion.
Pre-Matched to This Bundle's 11-Speed Cassette
Set the EDS TX to 11-speed in the WHEELTOP app after pairing, and it's dialed in for the SUNSHINE-SZ cassette included in this bundle.
The EDS TX Oversized Pulley Cage variant upgrades the rear derailleur with carbon fiber hollow oversized pulley wheels — available on this bundle as an upgrade option.
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 EDS TX Oversized Pulley Cage rear derailleur runs the same 800mAh electronic platform as the standard TX, upgraded with carbon fiber hollow oversized pulley wheels — lighter than standard, stiffer under load, and noticeably smoother under hard pedaling effort.
Same Platform. Carbon Fiber Upgraded Pulleys.
The TX Oversized Pulley Cage shares the same 800mAh battery, Pogopin charging, BLE/ANT+ wireless, and app configuration as the standard TX rear derailleur. The performance gain comes entirely from the carbon fiber hollow oversized pulley wheel system — no learning curve, no setup difference.
Why Oversized? The Chain Wrap Angle Difference.
At 12 teeth, the oversized pulleys are physically larger than a conventional jockey wheel — letting the chain bend through a gentler arc at each engagement. Less arc per revolution means less per-link articulation friction across every pedal stroke. The hollow carbon fiber construction removes mass from the pulley body without sacrificing torsional stiffness, keeping the drivetrain quieter and more responsive under load.

Front Drivetrain — Included with Every Build
Electronic Front Derailleur — Complete 2× Groupset
Every build ships with both the front derailleur and rear derailleur, matched to the RACEWORK double chainring crankset below — a complete 2× drivetrain, ready to install.
Precise Front Shifting on Demand
The EDS TX front derailleur runs on its own built-in 600mAh rechargeable battery and shares the same 8.4V system, magnetic Pogopin charging, and BLE/ANT+ wireless link as the rear unit. Pair both derailleurs to the WHEELTOP app for synchronized setup, gear mapping, and live status — front and rear shift in concert with a single button press from the lever.

Carbon Fiber Body. Rim Brake Compatible.
The carbon fiber lever body is lightweight, rigid, and built to actuate the RACEWORK calipers included in this bundle through a standard rim brake cable. Shift electronically on a button press while braking through the lever in the same motion you already know. No hydraulic lines to bleed — just cleaner cockpit routing and instant gear response.
Lightest EDS TX Configuration
Without hydraulic calipers, the Rim Brake build is the lightest complete EDS TX kit — front derailleur 191.3g, rear derailleur 336.6g, left lever 202.3g, right lever 214.6g.
A 6061 aluminum crank arm paired with CNC-machined 7075 aluminum chainrings — matched to the EDS TX front derailleur above and ready to bolt straight onto a threaded bottom bracket shell.
Matte Black 6061 Crank Arms. Real 7075 Alloy Rings.
The GRS-RK2 crank arm is 6061 aluminum construction at 170mm — no length options, so it's a straightforward fit for the vast majority of road frames. The chainrings are CNC-cut from 7075 aluminum, the same grade used in premium aftermarket rings, for consistent shifting under load and long-term wear resistance, and mount to the spider on a 3-bolt direct-mount pattern rather than a traditional 4/5-bolt BCD. A 24mm straight spindle threads into a BB51-standard bottom bracket, finished in matte black throughout.

Need a DUB Spindle Instead?
This crankset is also available in a DUB spindle version. If your frame or bottom bracket needs DUB instead of the standard 24mm spindle, leave us a note at checkout and we'll arrange it.
Quick Shift Design
The chainring pair is CNC-machined from a single piece of 7075 aluminum for a one-piece integrated construction — high strength and lightweight, without the flex of two separately bolted rings. The precision-cut tooth profile is shaped to guide the chain between rings faster and more predictably, for significantly improved shifting efficiency.
Compact
50-34T
The easier-spinning ratio — noticeably more manageable on long climbs and rolling terrain. The natural pick for most road and gravel riders, and for anyone pairing with the wider 11-32T or 11-34T cassette options below.
Mid-Compact
52-36T
A taller top end for faster group rides and flatter routes, while the 36T inner ring still leaves a manageable gear for moderate climbs. Best suited to stronger riders or those on rolling-to-flat terrain.
Hollow-Milled Crank Arm Design
Forged and CNC-machined, the crank arm is cut away in a hollow rib pattern along its length — lighter in weight, with higher strength and power-transfer stiffness than a solid arm.
660g for the Complete 50-34T Crankset
The 170mm 6061 aluminum crank arms and 7075 aluminum 50-34T chainrings come in at 660g together (bottom bracket not included) — a straightforward, budget-friendly alternative to the carbon fiber version of this crankset.
BB51 Threaded Bottom Bracket, Cups Included
The crankset ships with its matching BB51 threaded bottom bracket cups — no need to source one separately. BB51 covers both 68mm and 73mm threaded shell widths, so it fits most standard road and MTB threaded frames. Threading straight into a standard threaded shell also sidesteps the creaking that press-fit bottom brackets are notorious for.
Is Your Frame Compatible?
As long as your frame's bottom bracket shell is BSA (English thread) — the most common standard — this bottom bracket installs without any issue.
Complete Groupset Bundle
SUNSHINE-SZ 11-Speed Cassette — Three Range Options
Precision-cut 11-speed cogs on a standard Shimano HG-compatible driver — pick the range that matches your terrain and set the EDS TX to 11-speed in the WHEELTOP app to match.
This Cassette Uses Shimano HG Freehub Bodies
SRAM XD
SHIMANO HG
HG Driver Only — Not XD/XDR Compatible
This cassette installs on a standard Shimano HG-splined freehub body. It does not fit a SRAM XD or XDR driver. Confirm your rear hub's freehub body before ordering.
Each cog is precision-machined for clean, quiet engagement, and the whole cassette is a straightforward drop-in for a standard Shimano HG freehub body — no special driver needed. Because the EDS TX sets its speed count entirely in the app rather than through a fixed cable-pull ratio, it indexes cleanly against whichever range you choose below.
Close Ratio
11-28T
11-12-13-14-15-17-19-21-23-25-28T · 307.6g
Tight steps between gears for flat-to-rolling roads where you want to hold a precise cadence. Pairs naturally with the 52-36T chainring.
All-Rounder
11-32T
11-12-13-15-17-19-21-23-25-28-32T · 365g
The middle-ground range — enough spread for mixed terrain and moderate climbs without giving up too much at the close end. A safe default for most riders.
Wide Range
11-34T
11-12-13-15-17-19-21-23-25-28-34T · 377g
A genuine bail-out gear for hillier routes or riders who'd rather spin than grind. Pairs well with the 50-34T chainring for a climb-friendly setup.
Complete Groupset Bundle
SUMC SX11 Chain — 11-Speed
Sized and speed-matched to the cassette above, so there's no separate chain compatibility chart to cross-reference.
SUMC SX11 — 116-Link 11-Speed Chain
A dedicated 11-speed chain built with SUMC's double-X outer plate profile for smoother shifts under load and a slight friction reduction over a generic chain. Supplied at 116 links (standard length, trim to fit your frame during installation) and finished in silver to match the rest of the drivetrain hardware.

Before You Order
Compatibility & Buyer Notes
Please review the following before purchasing to ensure correct fitment.
Threaded Bottom Bracket Shell Required
The included crankset uses a BB51 threaded bottom bracket (68-73mm shell width). It is not compatible with press-fit shells (BB86/BB92/PF30, etc.). Confirm your frame has a threaded BSA-style BB shell before ordering.
Set the App to 11-Speed
The cassette, chain, and crankset in this bundle are all matched for an 11-speed drivetrain. After pairing, set the EDS TX speed count to 11 in the WHEELTOP app so indexing lines up correctly.
This Listing is for Rim Brake Only
The levers included are rim brake levers and the calipers are rim brake calipers — compatible with standard caliper brake cable pull. If you ride a disc-brake frame, please see our separate disc brake listing. Rim and disc brake components are not interchangeable.
App Pairing Required Before First Ride
After installation, pair both derailleurs to the WHEELTOP app over BLE, set your speed range, and run gear calibration. The app is free on iOS and Android.
Chain Needs Trimming to Fit
The chain ships at 116 links, the standard length for most road frames. It should be sized to your specific chainring/cassette/frame combination during installation using a chain tool.
