EXCLUSIVE VELO-PERSO.COM CONFIGURATION · TRACK · POWER METER
Your next personal best deserves accurate data.
On the velodrome, margins are measured in fractions of a second and accelerations in watts. We have brought together ROTOR ALDHU crank arms, a short Track30 spindle and the XCADEY XPOWER-S Gen2 144 BCD power meter spider to create a dedicated track crankset for riders who want to record, compare and improve their efforts. The specific ROTOR BSA30 Track bottom bracket is included.
At a glance: spider-based power measurement, stiff CNC-machined crank arms, 30 mm track spindle, 144 BCD five-bolt chainring interface and included BSA30 Track bottom bracket. Chainring not included: select the gearing that suits your event.
Velo-Perso.com's opinion
We developed this exclusive configuration because we wanted to offer track cyclists a genuine high-end crankset with integrated power measurement.
The velodrome is the ideal place to set records and build a meaningful power curve. You can compare standing starts, examine peak watts in a sprint or see how steadily you maintain your effort in a pursuit. Yet the choice of purpose-built track power meter cranksets remains limited.
We selected ROTOR ALDHU crank arms for their stiffness and outstanding manufacturing quality. CNC-machined 7075-T6 aluminium is ideally suited to the most explosive efforts. With the XCADEY power meter spider at the heart of the crankset, you can put all your power through the pedals, see the watts and save the data as you prepare for your next target.
Four components. One complete track crankset.
ROTOR ALDHU 30
A pair of CNC-machined 7075-T6 aluminium crank arms, available in seven lengths from 150 to 175 mm.
Track30 spindle
ROTOR's short 30 mm track spindle, designed for its ALDHU track crank architecture.
XCADEY XPOWER-S Gen2
CNC aluminium power meter spider with a track-standard 144 mm BCD five-bolt chainring interface.
BSA30 Track bottom bracket
The specific ROTOR track bottom bracket is included, for a 68 mm threaded BSA shell.
Record your watts. Improve your track performance.
The XCADEY XPOWER-S Gen2 measures total power transferred through the crankset at the spider. Power and cadence data are transmitted to compatible head units and apps via ANT+ or Bluetooth. Record each session and compare efforts as your training progresses.
- Sprint and keirin: compare peak power and the repeatability of successive accelerations.
- Standing starts, 500 m and kilo: examine power development and pacing.
- Pursuit: track consistent wattage and cadence over repeated laps.
- Training: build a power-duration profile from your sessions and races.
XCADEY technology: claimed ±1% accuracy, claimed 0–2,500 W power range, 30–220 rpm cadence range, rechargeable battery with magnetic USB charging, up to 350 hours of claimed battery life and IP67 protection. The XCADEY app is available on iOS and Android.
Power is measured in total at the spider. Any left/right balance value is estimated; it is not based on two independent left and right power measurements.

Fit and compatibility
Velo-Perso.com has mechanically checked the configuration combining ALDHU 30 crank arms, the ROTOR Track30 spindle, XCADEY 144 BCD power meter spider and the BSA30 Track bottom bracket. The supplied bottom bracket is intended for a 68 mm threaded BSA frame shell. A standard road BSA30 bottom bracket should not be treated as interchangeable with the track-specific version.
Before ordering, check your frame's bottom bracket standard, clearance around the spider and drivetrain alignment. Final chainline depends on the chainring, assembly and frame. Please contact us if you need a fit check.

Frequently asked questions
Is a chainring included in the €699 price?
No. The price includes the crank arms, Track30 spindle, XCADEY power meter spider and ROTOR BSA30 Track bottom bracket. Select your 144 BCD track chainring separately.
Which bottom bracket is supplied?
The specific ROTOR BSA30 Track bottom bracket for a 68 mm threaded BSA frame shell. It is included with this configuration.
Does the power meter independently measure both legs?
No. It measures combined power at the spider. Left/right balance on compatible displays is an estimate, not a pair of independently measured power readings.
Which bike computers can I use?
The XCADEY broadcasts via ANT+ and Bluetooth 4.0. Make sure your bike computer, watch or app supports power meters using one of these protocols.
Why choose shorter crank arms for track cycling?
Depending on your event and riding position, shorter arms can make high-cadence pedalling easier and improve clearance. Lengths are 150, 155, 160, 165, 170, 172.5 and 175 mm.
Will this crankset fit every track bike?
No. The supplied BSA Track bottom bracket is intended for a 68 mm threaded BSA shell. Spider clearance and chainline must also be checked. Contact us before ordering if you are unsure.
