Wheeltop is looking to shake up the electronic shifting market by undercutting the big brands with a system that promises near-universal compatibility, no matter how many gears you’re running. It’s an ambitious approach with a few clever features, but in practice, it struggles to match the performance and refinement of the established players.

Wheeltop EDS OX2.0 Wireless Electronic Shifter and Derailleur – Technical details
Wheeltop is a rapidly growing brand offering both mountain bike and drop-bar electronic shifting and braking systems, all of which are fully wireless. The company is based in China but also operates a European base and has recently acquired a stake in the Spanish brand, Rotor. This acquisition is likely the reason for the similarities in appearance between the EDS OX2.0 and the newly released Rotor Uno Wireless groupset.
The EDS OX2.0 system is set up and managed through a dedicated app, available for both Apple and Android devices. Unlike most rival systems, which are limited to a specific number of gears, the EDS OX2.0 can be configured via the app to work with anything from three-speed to 14-speed setups. It supports cassette ranges from 10 to 52 teeth, so in theory it should work with just about any bike.
Shifting is handled via ANT+ communication, and the rear derailleur includes a clutch, referred to by Wheeltop as a damper, with adjustable tension.
The kit includes a rear derailleur, shifter, and a charging cable. The derailleur charges via USB-A and houses an 800mAh battery, while the shifter is powered by a CR2032 coin battery.
Claimed weights are 400g for the derailleur and 70g for the shifter, with actual measured weights of 411g and 69g, respectively. For comparison, SRAM’s GX AXS (non-T-Type) setup weighs 463g for the derailleur and 63g for the band-on shifter, while Shimano’s new XT Di2 equivalent is claimed at 451g and 97g for the shifter. Deore Di2 would be a more accurate comparison, but Shimano has not yet published weights.
Wheeltop EDS OX2.0 Wireless Electronic Shifter and Derailleur – Performance
During testing, I used the Wheeltop EDS OX2.0 across two different setups: first as a replacement for a SRAM GX AXS drivetrain, and later on a fresh build. Unfortunately, both installations presented problems, and neither resulted in a perfectly functioning system.
The rear derailleur includes the usual range of adjustments, such as index screws and b-tension adjustment, although some, such as the low limit screw, require removing a small cover held in place by a very small 1.5mm Allen key. Beneath it sits a small O-ring to keep the area watertight, and the clutch tension can also be adjusted here.
Initial setup proved to be a real challenge, mostly because of the app and the language used within it. While the interface is in English, the translation is clearly literal (from Chinese), and key instructions often make little sense. This, combined with a few unclear setup steps, makes the process far more frustrating than it should be. Although the app features an initial setup guide, there is no clear pathway through, and the “initial setup” steps were more complicated, not well-explained, which led to far more issues later.
I ran into various shifting issues, including trouble engaging the smallest cog and, at times, inconsistent shifting across the cassette and onto the largest cog. Wheeltop doesn’t provide a B-tension adjustment guide, though a SRAM version can be used to fine-tune the setup if you already have one.
Moving to the shifter, it’s a fairly bulky unit and somewhat awkward to install due to its non-split clamp, which means the right grip needs to be removed first. This is less of an issue with lock-on grips, but more inconvenient for foam, silicone, and push-on grips. Despite its size, the button layout is well considered, with a good reach and some tactility on the buttons that make shifting easy once set up.
Button functions can be reassigned through the Wheeltop app, which is one of the few processes that works smoothly. Pairing the shifter to the derailleur is also relatively straightforward, although the two selectable modes, shared and lock, are poorly explained. It’s unclear whether these refer to Bluetooth connection settings or another app-related feature, but the system defaults to shared mode.
One potentially useful feature is the ability to fine-tune individual gear shifts via the app. Like SRAM’s T-Type AXS, at least, it allows users to fine-tune the derailleurs’ position under particular gears.
It’s a useful feature if one or two shifts on the cassette feel slightly off, allowing targeted micro-adjustments without affecting the rest of the setup. That said, the gauge poses a fairly poor, and perhaps too fine, reference. Manually adjusting individual shifts on a scale from 0 to 1500 is unlikely to appeal to the majority of riders, and it may become confusing.
Once dialled in as best as possible, shifting performance is reasonable. The motion is smooth enough, and one clear strength is battery life. The EDS OX2.0 derailleur houses an 800mAh battery, compared to 300mAh in SRAM’s AXS units and 305mAh in Shimano’s new wireless battery. Both those systems use removable batteries, while Wheeltop’s is fixed within the derailleur. Even against Shimano’s wired Di2 setup with its 500mAh BT-DN110 battery, Wheeltop’s capacity is greater.
The brand claims up to 20,000 shifts per charge, and although I didn’t count, the battery does seem to last noticeably longer than its rivals. Charging is done via the supplied USB-A cable, which connects to a proprietary port on the derailleur; therefore, it’s worth keeping that cable safe.
There are two shift speed settings: Leisure Mode (the default) and Racing Mode, which quickens shifting at the expense of battery life. The difference is small but noticeable, though even in Racing Mode, it doesn’t feel faster than rival wireless drivetrains.
At present, Wheeltop doesn’t offer any additional wireless shift accessories, such as SRAM’s Blip or Shimano’s satellite shifters. While the standard unit will be sufficient for most mountain bike riders, it limits flexibility for those wanting remote shifters for aero extensions or alternative cockpit setups. This is an area where Wheeltop still lags behind the established brands.
Wheeltop EDS OX2.0 Wireless Electronic Shifter and Derailleur – Verdict
On the first bike setup, I spent several hours trying to get the shifting to work, assuming the issues lay somewhere within the bike itself. I checked and replaced the mech hanger, confirmed the chain length, and adjusted the limit screws, B-tension, and clutch tension before eventually giving up. On the second bike, I seemed to be going back and forth constantly, always trying to improve the shifting as it was never quite right.
The contrast with SRAM and Shimano is stark. Both offer apps that are far more intuitive and reliable, and while neither system can be configured to work across such a wide gear range as the Wheeltop, they simply function as intended. Setup is straightforward, shifting is consistent, and you can use the full spread of gears without issue.
While the Wheeltop kit is cheaper, the difference is not as large as you might expect. It is priced at £350 for the shifter and rear derailleur, while SRAM GX AXS is £530 and Shimano’s new Deore Di2 is roughly £590, both at full retail including a battery and charger. In reality, both groupsets are often available for considerably less through online retailers, which further reduces the Wheeltop price advantage. Another factor to consider is after-sales support. Although Wheeltop now has a European distribution centre, this does not compare to the convenience of being able to buy and service parts through your local bike shop.
Overall, using the Wheeltop system has been a frustrating experience. Having used both SRAM AXS and Shimano Di2 drivetrains, the EDS OX2.0 feels like a step backwards. While it has potential, a long battery life, and a few interesting ideas, it lacks the refinement, reliability, and ease of use offered by the established brands.
