I wanted to test the waters of power measurement before jumping in with two feet on a more expensive power meter. So, I purchased the Velocomp AeroPod which is a device that is mounted on the handlebars on a traditional bike. It senses wind speed and elevation gain and triangulates off of your existing ANT+ cadence/speed sensors (not included) to calculate your power output in real time.
On the v20, I made a slight modification to the unit's clamping system to make it mountable on my light-mount above the bottom bracket. The unit worked well after I reduced the factory set CdA down to values that myWindsock kept averaging for me (since it came factory preset to upright bike CdA avg of way higher - which was nice in terms of overstating my power and came as a huge ego-killer once I corrected it). :-D
Long story short, it was like a gateway drug and now that I'm sold on measuring power, I decided to upgrade to a Rotor Spider meter. I figure I can pay it forward by offering this unit to another CB rider at a 50% discount - for a unit that saw <4 months of use. The mod I did would not be loved by upright riders because I had to grind out part of the unit's attachment points to angle down on the front of the v20, but for "us" it's a perfect solve. See attached pics and let me know if you want it.
Paid $478 ($449+tax) on May 14th, 2022
Selling for $225. Throwing in a $15 USB-Micro to USB-C cable needed to access free power analysis software on a computer (this is also where you can make manual adjustments to the unit's variables like CdA). Also including 2 $5 GoPro mounts I had to combine to fit the unit on the front of the v20.
I will cover shipping costs.
