The COOSPO S10 aluminium power meter crankset adds accurate power measurement to a road bike without requiring power meter pedals or a separate power meter crank arm.
The power meter is fully integrated into the crank spider and measures the total power transferred through both crank arms.
This version uses durable aluminium crank arms and a 29 mm spindle. This is the same spindle diameter used by SRAM DUB cranksets, allowing the S10 to be combined with many existing SRAM DUB-compatible bottom brackets.
Spindle diameter alone does not guarantee complete compatibility. Always check the frame’s bottom bracket standard, bottom bracket shell width, required spacers, spindle length and desired chainline before installation.
The S10 uses a 110 BCD four-bolt spider. Suitable road chainrings with the same mounting pattern can be installed. Many Shimano-compatible road chainrings also use a 110 BCD four-bolt pattern, although the exact bolt position, chainring shape and spider interface must still be checked.
The spider power meter has a claimed accuracy of ±1% and a maximum measurement range of 2,800 watts. In addition to total power, it records cadence, left-right balance and pedal smoothness.
ANT+ and Bluetooth connectivity allow the power meter to communicate with compatible cycling computers, sports watches and training apps. Settings, calibration and firmware updates can be managed through the CoospoTools app.
The integrated rechargeable battery provides up to approximately 300 hours of use and is charged with the supplied magnetic charging cable. The IPX7 water-resistance rating makes the crankset suitable for training and racing in wet conditions.

SPIDER POWER METER
The power meter is positioned centrally in the crank spider. This allows the system to measure the total force transferred through both crank arms.
The COOSPO S10 records:
• Total power
• Cadence
• Left-right balance
• Pedal smoothness
The claimed measurement accuracy is ±1%. The power range is 0 to 2,800 watts and the cadence range is 20 to 240 rpm.
29 MM SRAM DUB-COMPATIBLE SPINDLE
The crank spindle has a diameter of 29 mm and can be used with many bottom brackets designed for a SRAM DUB-type spindle.
Possible bottom bracket standards include:
• BSA with a suitable DUB bottom bracket
• BB86 or BB92 with a suitable DUB bottom bracket
• PF30 with a suitable DUB bottom bracket
• BB30 frames with an appropriate adapter or bottom bracket
• T47 with a suitable DUB bottom bracket
Actual compatibility depends on the frame, bottom bracket shell width, spacers and required chainline.
CHAINRING COMPATIBILITY
The COOSPO S10 uses a 110 BCD four-bolt chainring mounting pattern.
Check the following before ordering:
• Chainring BCD
• Number of mounting bolts
• Bolt-hole position
• Chainring shape
• Spider interface
• Required chainring combination
• Compatibility with the drivetrain speed
Please note that a SRAM DUB-compatible spindle does not automatically make the crankset compatible with SRAM AXS chainrings. Many SRAM AXS chainrings use an eight-bolt direct-mount fitting and do not install directly onto this 110 BCD four-bolt spider.
CONNECTIVITY AND APP
The COOSPO S10 supports ANT+ and Bluetooth and can be connected to a wide range of compatible cycling computers, sports watches and training applications.
Compatible devices and platforms include:
• Garmin
• Wahoo
• Hammerhead
• Zwift
• TrainerRoad
• Other devices and apps supporting ANT+ or Bluetooth power meters
The CoospoTools app can be used to:
• Calibrate the power meter
• Adjust settings
• Install firmware updates
• Check the battery status
The S10 supports automatic calibration, manual calibration and back-pedal calibration.

FAQ
Does this crankset fit every SRAM DUB bottom bracket?
Not automatically. The spindle uses the 29 mm DUB diameter, but shell width, spindle length, spacers and chainline must also be correct.
Are chainrings included?
No. Suitable 110 BCD four-bolt chainrings must be purchased separately.
Is a bottom bracket included?
No. A suitable bottom bracket for a 29 mm DUB-type spindle is required.
Do SRAM AXS chainrings fit?
Not directly when they use SRAM’s eight-bolt direct-mount interface. This crankset uses a 110 BCD four-bolt spider.
Does the power meter measure both legs?
The spider power meter measures the total power transferred through both crank arms and also provides left-right balance data.
Which cycling computers are compatible?
ANT+ and Bluetooth allow the power meter to connect with many Garmin, Wahoo and Hammerhead cycling computers.
How is the battery charged?
The integrated battery is charged with the supplied magnetic charging cable.
Can the crankset be used in the rain?
Yes. The power meter has an IPX7 water-resistance rating.
