▲What you see is what you get out of the box, the VECTOR 3 body is properly placed in the inclined cardboard slot, neat and in place

The most significant update of this generation of VECTOR 3 is the integration and higher integration. It now looks more like a pair of ordinary road self-locking pedals. The signal transmitter and battery compartment of the previous two generations of external mounting have been further simplified. And integrated into the lock pedal body, there is no longer any protruding parts other than the lock pedal, there is no need to worry about crashing, parking, bending and pedaling acceleration to cause damage to key components, the overall sealing is stronger and its service cycle is correspondingly extended. .

The appearance of the VECTOR 3 power meter pedal has a large number of rounded lines. The overall feeling is like the Shimano SPD-SL series pedals of “increase and bold”, the composite carbon fiber body is still replaced by EXUSTAR. Work, consistent with the past, using the LOOK KEO self-locking system.

Use a 4mm Allen key to turn the aluminum primary color nut on the outside of the half-lock pedal one turn to open the VECTOR 3 battery compartment. Although the nut looks large, the actual space inside the pedal body is very limited. The VECTOR 3 uses the V13GA small button battery commonly used in calculators, digital thermometers, and digital vernier calipers. The shrinking battery also reduces the official battery life of VECTOR 3 to about 120 hours.（Continuous riding）, It’s probably the total amount of cycling in a month.

VECTOR 3（Two-sided version）The general working principle is to use the built-in multi-directional piezoresistor tensiometer in the axis to measure the force shape of the metal component of the axis when the rider stepped on it, and then to match the speed measured by the accelerometer integrated in the same. The data measured by the left pedal will be first transmitted to the right pedal, and the data on both sides of the right pedal will be integrated and then transmitted to the computer by ANT+. The output and pedal of the rider are calculated by the computer. Data such as frequency, and finally presented on the screen.

The self-locking part of VECTOR 3 provides a considerable range of 20-grid cleat tension adjustment gears. You only need to use an ordinary 3mm hex wrench to adjust the force of the cleats in and unlock, and lock the pedals. The buckle at the end of the body also has an indicator of tension and tightness, which can easily find the tightness that matches personal needs.

VECTOR 2（Bilateral measurement）And VECTOR 2S（Unilateral measurement）The LED indicator on the external battery compartment is moved to the center of the pedal lock in VECTOR 3. Yes, yes, it is the position of the black plastic cover that locks the pedal shaft. The power unit detects that it is starting to step on, stop stepping on, or When entering sleep, low battery and other states, the LED indicator will flash the corresponding number and color.

In the box, VECTOR 3 comes with a pair of 6° floating ARC R2 lock plates, a set of lock plate screw gaskets, a pair of lock pedal 2MM gaskets, a product installation instruction, product information and safety instructions. this.

Garmin''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s weight reduction in this round is worthy of recognition. The curb weight of the VECTOR 3 power pedal body with 4 V13GA batteries is only 321.6 grams, which is compared with the prototype EXUSTAR without power modules and electronic components.（Vast）The PR200 road self-locking pedals weighed about 70 grams.

▲The first step of installing VECTOR 3, carefully read "VECTOR 3/3S Installation Instructions"

The VECTOR series power meter platform is designed with full consideration of user convenience. The installation and operation of VECTOR 3 requires a 15mm open-end wrench.（Lock pedal wrench）, Grease and an optional vernier caliper（Can also be replaced by 2MM Allen wrench）, With these, you can start loading the car!

Remove the original pedals on the car, use a rag, paper towel, or even someone else’s clothes to clean the mounting holes of the pedals. After cleaning, it is necessary to develop a good habit of applying grease to the thread before the pedal is installed. Some people like to apply it on the spindle of the pedal, and some like to apply it in the mounting hole, as long as the grease can fully cover the thread Just fine.

Well, finally it’s the installation process. Use a 15mm open-end wrench to tighten the VECTOR 3 to the crank with a torque of about 34NM. How powerful is this “34NM”? It’s a bit lower than the 40NM of the locking flywheel. If you think you can’t control the strength of the locking, you can also go to a professional car shop to find a professional technician to use professional techniques and strength to professionally tighten the professional VECTOR 3 To your professional bike.

After proper installation, shift to the smallest flywheel of the large plate, use a vernier caliper or a simple 2mm Allen key to check the distance between the indicator light protruding from the inner side of the VECTOR 3 axis and the chain, riser, and chainstay to ensure the gap between them It is greater than 2mm; if it is less than 2mm, use the attached 2mm pedal pad to increase the gap.

Hold the lock and turn the crank in a circle, wake up the sleeping VECTOR 3, use the computer to connect and pair and perform the zeroing operation, and then open the cruel door of power training, and step onto the “Xiuxianqi” road.

It’s worth mentioning here that “return to zero”（ZERO）And “correction”（SLOPE）They are two completely different things. The “correction”function on the Garmin GPS code table realizes only the “manual zeroing”operation.

“correction”（SLOPE）, Refers to the adjustment of the power curve of the power meter, generally without the user''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s own operation.

“Return to Zero”（ZERO）, Means to clear it when the power meter is not stressed. “Return to zero” is carried out every time the user rides, because the accuracy of the power meter is affected by external environmental factors（Such as temperature, air pressure, etc.）, Often “zeroing”can ensure data accuracy.

The entire installation process only takes less than 5 minutes. It can be seen that Garmin''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s optimization of installation convenience further reduces many unnecessary installation steps and eliminates misoperations that can occur during the process.

After connecting to VECTOR 3, GARMIN EDGE 1030 can record more power items than other brands of power meters. The less common and seemingly complicated left and right power phase data indicate that the left and right sides are stepped on. The crank range of useful work; the left and right power phase peaks, as the name implies, is the crank angle of the pedal output peak; the average platform center offset（PCO）It is the offset of the force point from the center of the pedal. From these data, we can also see the cleats that took only ten minutes to set up from Shimano SPD-SL to LOOK KEO, and there is still room for further optimization; the posture of the author who had fractured the clavicle of his right shoulder while riding There is a noticeable left side tilt.

In the data comparison of the formal trial, the author chose the QUARTQ DZERO RED disc claw power meter as the reference group for the VECTOR 3 power meter lock. Both power meters have been reset to zero three times before starting, and the code table for data collection It is GARMIN EDGE 810 and EDGE 1030, and the subsequent data analysis is carried out in Training Peaks WKO+ v3.0.
