Do You Set Your Wheel Size In Your Speed Sensor? 😂 

If you ask me what I set it as, at the moment, 2136 😂

😂😂 oh man..now u make my feelings up and down again 😂 so stay with 2136 or set it auto? 😂

@Melvpedals it's up to you. I like the idea of a static size, because a bad GPS day will not make you feel slower (actually in your case, static size makes you "slower" in numbers). Here's what cateye instructions look like: Tire circumference may change depending not only on tire size, but also on tire type, air pressure, the weight of the rider, and other factors. To facilitate initial setup, the above "Tire circumference reference table" is contained in the instruction manual. However, if you would like more accurate measurement you will have to measure manually. That just means it's also not accurate if you forgot to pump your tires before going out 🤪 Anyway, what you can do, is, on a stretch where there are no trees, set the GPS to max accuracy (multiband), switch to automatic (must be from a static value), and cycle for 1km, I believe the resulting calculated value will be the closest you can get as your circumference at the current time.

@@WariWahab Good info! Thank you so much!
