Chinese brand Whaleroad has launched a new wireless drivetrain called R7, which features a whopping 14-speed cassette.
We spotted the new Whaleroad R7 drivetrain fitted to a Cykl Graave at the Sea Otter Europe trade show in Girona.
Whaleroad isn’t the only Chinese cycling brand to release a drivetrain that’s compatible with 14 speeds. Wheeltop’s EDS derailleurs can also be configured for up to 14 gears. But this is the first time we’ve seen such a system paired with an actual 14-speed cassette.
Antoine Delmur, the founding director of Cykl, said of the R7 drivetrain: “We've been testing it for a little while now and, so far, it's really impressed us.”
418% gear range
Whaleroad says its 1x14-speed cassette offers a 418 per cent gear range, spanning from an 11-tooth smallest sprocket to a 46-tooth largest sprocket.
The cassette fits a conventional Shimano HG freehub body, meaning there's no change needed to proprietary standards.
Squeezing the extra gears into that space has seen the cogs on the bottom of the block become significantly narrower.
Wireless derailleur
Whaleroad’s R7 derailleur is wireless and uses a removable 725mAh battery. Whaleroad claims up to 1,500km of riding from a charge.
The battery uses a USB-C port, and Whaleroad says that a 10-minute charge is enough for 200km of riding.
An accompanying app enables riders to customise shifting and update the firmware.
Similar to Wheeltops EDS, Whaleroad says the derailleur can be programmed to work with anything from a three-speed to a 14-speed cassette.
The rear derailleur also features an adjustable clutch, IP67 weatherproofing and what Whaleroad calls an “Impact Protection System”, designed to enable the derailleur to realign itself following an impact.
Is 14-speed the next frontier?
The arrival of another 14-speed drivetrain comes as the established drivetrain manufacturers continue to add sprockets of their own.
SRAM’s flagship road groupset remains 12-speed, although its 1x Red XPLR AXS gravel groupset moved to 13 speeds in 2024, pairing a 10-46t cassette with a direct-mount rear derailleur.
Campagnolo went one step further in 2025, launching Super Record 13 as the first 2x13-speed wireless electronic road groupset.
The current Shimano Dura-Ace R9200 groupset has 12 speeds, but that looks set to change.
What appears to be the unreleased Dura-Ace R9300 groupset has already been spotted in use at the Vuelta a España with a 2x13-speed setup. There have been previous leaks, including a mysterious 13th sprocket appearing in Shimano’s E-Tube app, which have further strengthened the case for Shimano moving to 13 speeds.
If that happens, Whaleroad’s 14-speed setup will still have one more sprocket than the flagship offerings from cycling’s drivetrain giants.
Whether you actually need it is another question.
