SRAM POWER METER · SHIMANO SHIFTING

AERO 2X for Shimano Drivetrains

THREAD MOUNT 2X

Chainring set for a SRAM AXS Thread Mount power meter on a Shimano 12-speed road drivetrain. 52-36T and 54-40T, machined in Poland.

Configure & buy
Two systems

SRAM power meter with Shimano shifting. Now its possible.

Power meter

SRAM AXS Thread Mount on an 8-bolt DUB crank

The power meter bolts to the crank. The rings mount to the power meter.

Shifting

Shimano 12-speed drivetrains

Dura-Ace R9200, Ultegra R8100, 105 R7100 Di2 and 105 mechanical.

Anatomy

Back and front

Drag the handle to compare the two sides of the set.

Backside. The working side. The inner ring mounts here on four 5 mm hex bolts (10 Nm maximum), and the shift ramps and pins are milled into this face so the chain climbs from the inner ring to the outer. The Thread Mount interface in the centre fastens the set to the SRAM AXS power meter; removing it takes the SRAM Thread Mount tool.

Frontside. The visible side. The AERO pattern runs across the whole outer face, a relief machined into the aluminium that changes with the light and the viewing angle. Anodized in one of ten colours, it is the face the bike shows.

BACKSIDE

FRONTSIDE

Fitment

Shimano 12-speed, front to back

The 44.5 mm chainline puts the rings where the Shimano front derailleur expects them. Everything behind the crank stays Shimano.

Cut in the same pass

The relief on the outer ring is milled in the same CNC pass as the ring itself, then anodized with it. It changes with the light and with the angle of the crank.

Powermeter
 Thread Mount Powermeter DUB AXS Spider
NOTE!

Not compatible with Sram front derailleurs and Sram chains

The Thread Mount interface provides compatibility with the appropriate power meter mounting system, but does not make the chainring set compatible with Sram shifting components

Recommendations

  • NOTE: the Sram Thread Mount Removal Tool is required to remove and reinstall the chainrings
  • It is also a good idea to use a new chain with your new ALUGEAR chainrings
  • It is recommended to use a well-lubricated chain on every ride
  • We recommend using the optimal Alugear 2x chainring combinations for the best shifting performance. Other chainring combinations may result in less precise front shifting and may require additional front derailleur adjustment
  • The correct operation of the double set is guaranteed only when using Alugear outer and inner chainrings together
  • Tool holder: 5 mm hexagon socket maximum permissible torque: 10 Nm

Information

ALUGEAR AERO Chainring. Sram Powermeter. Shimano Shifting

ALUGEAR AERO Chainrings. Sram Power Meter. Shimano Drivetrain. One Integrated Solution.
The ALUGEAR AERO 2X Chainring Set was designed for riders who want to combine the clean, rigid and highly integrated design of a Sram AXS DUB Thread Mount Power Meter with the shifting performance of a Shimano road drivetrain.
Instead of being limited to a complete drivetrain from a single manufacturer, this solution brings together the advantages of both systems - Sram’s compact Thread Mount power meter architecture and Shimano 12-speed shifting - connected by a ALUGEAR chainring set engineered specifically to make the combination work.
The complete shifting geometry - including ramps, chain pick-up features, tooth profiles and their precise positioning - has been developed specifically for Shimano 12-speed road chains and front derailleurs.
Multiple strategically positioned engagement points around the large chainring provide more opportunities for the chain to engage during an upshift, helping deliver fast, precise and consistent shifting from the small to the large chainring.
The system uses an optimized 44.5 mm chainline, designed specifically for proper alignment and performance with Shimano 12-speed road drivetrains.

Compatibility & Installation
To build this configuration, a DUB crankset with an 8-bolt interface is required. The Sram Thread Mount Power Meter uses an 8-bolt interface to connect directly to the crankset.
As these cranksets use a DUB spindle, the bicycle must also be equipped with the appropriate DUB Road bottom bracket for the frame.
The system is assembled in three steps:
8-bolt DUB crankset → Sram AXS Thread Mount Power Meter → ALUGEAR AERO 2X Thread Mount Chainrings

Performance Meets AERO Design.
The AERO construction gives the drivetrain a clean, integrated appearance while creating a visually distinctive centerpiece around the Thread Mount power meter.
The large chainring features ALUGEAR’s signature Design; a three-dimensional surface is an integral part of the component, combining precision CNC manufacturing with ALUGEAR’s distinctive design language.

Together with 10 anodized color options, the AERO 2X allows the drivetrain to become an integral part of the overall bicycle design - from subtle, understated builds to completely custom bikes.

From CAD development and shifting geometry to CNC machining, finishing and testing, ALUGEAR AERO 2X Chainrings are designed, engineered and manufactured in Poland.

A solution created for riders who do not want to choose between Sram power measurement, Shimano shifting performance and distinctive Aero design.

ALUGEAR - Engineered to Perform. Designed to Stand Out.
