GEOID PM500 Power Meter for Bicycle with 16.5 cm Cranks Spider 4 Bolt 110 BCD ANT+ and Bluetooth Black For Cycling and Training by Watts
You already have the maximum available quantity in your cart.
The GEOID PM500 power meter is designed for cyclists who want to monitor their power output in watts during rides and training. The meter is integrated into the spider of the right crank, which features a four-bolt mounting for chainrings with a 110 BCD. The measured data is transmitted wirelessly via ANT+ and Bluetooth, allowing it to be displayed on compatible cycle computers, sports watches, or mobile applications. The set includes both the right and left crank, each measuring 16.5 cm. The black finish with the GEOID logo suits most modern bicycles.
- Power Measurement — the meter is integrated into the spider of the right crank, through which the force from pedalling is transferred to the chainrings. The power data in watts will help you more accurately manage your training intensity, evaluate individual rides better, and compare results over time.
- Wireless Connection — data is transmitted via ANT+ and Bluetooth. This allows you to connect the meter to cycle computers, sports watches, and mobile devices that support these protocols, as well as to training applications for use on a trainer.
- 16.5 cm Cranks — the set includes the right crank with spider and power meter, as well as the left crank, both measuring 16.5 cm. The cranks are connected by an axle that passes through the bottom bracket of the frame.
- 110 BCD Spider — the spider has four arms with bolts for mounting chainrings and a pitch of 110 BCD. Before purchasing, please ensure that your chainrings match this standard.
- Charging Connector — on the spider, there is a connector with two contacts for connecting the charging cable. It is accessible from the outside, allowing you to reach it even after installation on the bike.
- Usage — the power meter is suitable for structured training, monitoring performance throughout the season, and for even power distribution during longer rides and races.
- Training by Watts — power in watts is less affected by heat or fatigue than heart rate. Therefore, power measurement is suitable for interval training, performance testing, and planning pace on longer routes and hills.
- Installation — before installation, please ensure that the crank axle matches the bottom bracket of your frame. If you do not have experience with drivetrain replacement, we recommend having the installation done by a bike service.
- Colour — black with the GEOID logo on the spider.
- Package Contents — 1x GEOID PM500 power meter with 16.5 cm cranks.
The GEOID PM500 is a power meter for cyclists who want to train by watts and keep track of their performance. The spider with a pitch of 110 BCD and four bolts is complemented by cranks measuring 16.5 cm. With ANT+ and Bluetooth connectivity, it can be connected to standard cycle computers and training applications. Training by watts will help you more accurately dose your workload and monitor progress. Before installation, please check compatibility with the bottom bracket of your frame and with the chainrings.
