CompatibilityThe PowerTap P1 is compatible with all standard, road bike crank armsThe Garmin Vector is compatible with all standard, road bike crank arms up to 44 mm wideThe bePRO power meter is compatible with cranks arms that have a 9/16″-20 TPI thread and a thickness of at least 12mm – which is the vast majority of crank arms
ProsThe P1 Pedals have a power meter on each pedal, giving it the ability to measure true left and right powerThe Vector 2 locates a power meter on on each pedal, giving it the ability to measure true left and right powerSince the bePRO locates a power meter on each pedal, it can measure true left and right power
Easy installation. Installing the P1s isn’t much more complicated than installing a normal set of pedals. Grab a hex wrench and bolt them on! No torque wrench necessary. This also makes it easy to move the pedals from bike to bikeWhile the Garmin Vectors come with a set of LOOK Keo style cleats, the Vector can be modified to fit Shimano pedals. You can purchase a new DIY Vector Shimano Cartridge Kit that will allow the Vector 2 and 2S hardware to be swapped into a Shimano PD-6800 pedal bodyPriced right. At $824 for the bePRO, you have dual-sided power at a very reasonable price
The P1s transmit data via ANT+ as well as Bluetooth SMART, which means you have the choice of using a traditional head unit or a smartphoneThe dual-sided Vector 2 provides access to Garmin’s suite of advanced cycling dynamics data. Included in this data are things like power phase, peak power phase, platform center offset
ConsiderationsYou must use the cleats that come with your P1. The P1 uses cleats that are very similar to – but not exactly the same as – LOOK Kèo cleatsSome people don’t like the fact that the pedals require you to mount a pedal pod to the pedal spindleYou must use the cleats that come with your bePRO pedals. The bePRO uses LOOK Kèo style cleats. If you have LOOK Kèo original cleats, they will also be compatible with the pedals
The P1 Pedal’s stack height is 14mm, which is about 3-5mm greater than your average pedal. So you might want to raise your saddle by this amount to keep your bike fit the sameGarmin has stated that for best accuracy, it is advised to use standard, circular rings when using Garmin Vector pedalsThe bePRO power meter uses rechargeable lithium-ion batteries which have a 30-hour life. Rechargeable batteries eliminate the need to buy new batteries, however you have to be diligent about keeping your pedals charged
