We’re used to buying groupsets and components from the big three brands – Shimano, SRAM and Campagnolo – but there’s an increasing range of Chinese competitors filling a gap for lower priced groupset components. So here’s a rundown of five emerging Chinese competitor groupset brands and what each offers.
These companies haven’t come out of nowhere, with their founders often having worked for Shimano or SRAM as subcontractors or in these brands' factories in China before starting their own companies.
They are typically different to the big three. They sell individual components instead of complete groupsets, leaving you to source the rest of the parts needed. Many offer Shimano compatibility and there are also some SRAM compatible components.
You’re going to need to buy online, with AliExpress a favoured outlet and products shipped from China. The brands differ in the quality of information about their components and compatibility provided, so you may in some cases need to take a guess at how well a component will work with your other drivetrain parts.
On the other hand, you can expect to save a significant sum relative to the big three groupset brands, although look out for import duties or other additional charges.

Wheeltop
Wheeltop has been making groupset components since the 1950s and has recently taken a majority holding in the Spanish component brand Rotor. It has used its wireless electronics in the Rotor Uno groupset.
Wheeltop sells three wireless electronic groupsets, aimed at road, gravel and MTB use, which can be configured to work with cassettes with between three and 14 speeds. Wheeltop sells the derailleurs and shift levers and hydraulic brake callipers for some groupsets, but not other components – yet.
Its TX road groupset is 1x or 2x compatible, with carbon fibre parts and hydraulic disc brake callipers, although there is a cable brake alternative. It’s compatible with cassettes from 10 teeth up to 36 teeth.
EDS GeX is an electronic 1x gravel groupset with cassette compatibility ranging from 10 teeth up to 52 teeth and includes hydraulic brake callipers.
The EDS OX2.0 wireless electronic mountain bike groupset includes shifters and 1x rear derailleurs, with cage lengths for 46t and 52t maximum sprockets. It doesn't include brake callipers though.
Wheeltop’s latest offerings, which we spotted at the 2026 Taipei International Cycle Show, are a range of carbon cranksets and a fully wireless time trial groupset.
Magene
While Wheeltop has focused on derailleurs and shifters, Magene’s groupset focus is on power meters and cranksets.
The top spec TEO P515 power meter has carbon cranks and is available with crank lengths from 160mm and the full range of common road chainring combinations. It can also be bought as a spider only, although this is only compatible with Magene cranksets.
Magene also sells the QED and PES power meter cranksets, made of aluminium. There are options compatible with a wide range of bottom brackets and all Magene’s power meters support both ANT+ and BLE protocols, for compatibility with a full range of cycling computers.
The P715 dual-sided pedal power meter is available with Look Keo and Shimano SPD-SL cleat compatibility.
The brand also has a line-up of wheels, ebike components, lights and a rearview radar and its cycling computers and smart trainers are used by the XDS-Astana WorldTour pro team.
It showcased a range of electronic shifting components at the 2025 Eurobike trade show, although as of May 2026 it's yet to bring these to market.
L-Twoo
L-Twoo offers a wide range of groupsets for road, gravel, triathlon, mountain bike and folding bike use, as well as electric bike components.
The company only sells derailleurs, shifters and hydraulic brake callipers and six-bolt rotors, so its components need to be paired with a cassette, crankset and chain from another brand. But it offers 1x and 2x electronic and mechanical shifting systems with up to 13 speeds and shifters that work similarly to either Shimano or Campagnolo.
Electronic systems have wireless transmission from the shifters to the derailleurs. Road electronic groupsets are powered by an in-frame battery that’s similar in size to Shimano’s, but 1x gravel and mountain bike rear derailleurs have a non-removable battery housed in the derailleur and charged via a USB-C port.
Sensah
Sensah sells road, mountain bike and folding bike groupset components, with its own dedicated store on AliExpress as well as a combined Chinese/English language website.
As with L-Twoo, it sells the shifters and derailleurs, but not the other components needed for a complete groupset. All its current components provide mechanical shifting only.
On the road and gravel side, the HRD groupset offers hydraulic systems with 7 to 13 speeds and 1x and 2x compatibility. 1x gravel derailleurs have a clutched cage and up to a 50t maximum sprocket compatibility, dependent on speeds.
Mountain bike groupsets offer 1x, 2x and 3x systems with between 7 and 13 speeds and derailleur capacity of up to 52 teeth.
Folding bike components provide trigger shifters with up to 2x11-speed compatibility.
S-Ride
Uniquely among the brands here, S-Ride sells cassettes and chains, as well as road, gravel and mountain bike derailleur systems. All that’s lacking from its component range are cranksets and brake callipers.
Eliminating the guesswork, S-Ride provides detailed compatibility information for its parts with Shimano components.
S-Ride's road and gravel components include mechanical shifters and front and rear derailleurs with between 8 and 11 speeds. 2x options offer 8/9 and 10-speed derailleurs with 34t maximum sprocket compatibility, while 1x gravel derailleurs come in 10, 11 and 12-speed variants with 50t maximum sprocket size.
There are MTB derailleurs with 7 to 12 speeds and up to 52 tooth cassette compatibility, as well as 7/8 and 9-speed components designed for electric mountain bikes. S-Ride sells both trigger and twist shifters.
Cassettes range from 7-speed, with a maximum 11-36t to 12-speed with 11-46t and 11-50t ranges suitable for 1x MTB use and include e-MTB 7, 8 and 9-speed options. S-Ride's chains suit drivetrains from seven to 12 speeds.
