Sigma Sport Bicycle Computer – How to Set Wheel Size I’m making this video just so I won’t have to find or read the manual again! I don’t really understand this, but here are the wheel size settings I use (which are for MPH): 16×1.75×2 = 0790 20×1.75×2 = 0988 24×1.75×2 = 1184…

Hey! Great and helpful video, especially with the wheel size chart in the text description. How nice. Thank you.
I googled Sigma Sport because I lost my manual and didn’t know how to reset the wheel size setting and your video came up! Hooray! Thank you for posting this invaluable information!

Invaluable! Thank you for making this!
Really helpful, lost instructions just just searched and found your video. Thanks
so if u stop ur bike it continues to count?
i have 26×2.1 could anyone help me with WS? thnx
me too
I don’t have this exact model, but the video was still helpful in figuring things out. (no manual) Thanks.
This is what youtube is for. You’re a star. Thank you very much.
Thanks to your posting, I was able puzzle out the correct information for my Tires. Here is the formula for odd sized tires:
For KPH: Enter the circumference of the tire connected to the computer in Millimeters. (i.e. roll the tire on the ground, and measure the distance of one complete revolution.
For MPH: Multiply the millimeters from above by 0.6124 (the conversion from kilometers to miles).
Thanks again!
Thanks, very helpful, I was stuck with the wheel size since I lost my instruction booklet.
THANK YOU!!!!!!!!! YOU ROCK
Does the screen light up (and stay lit up until you toggle it off) for reading it at night?
This was great! I lost my manual and couldn’t find anything on the Sigma site. Needed to change from km to mi, which you showed, but you also reminded me to adjust my wheel size for new tires. Thanks!
Does width have anything to do with it? I have 700×23c wheels, so will it be the same as this (1342)?
do u think it would work for an 8″ wheel
I don’t know what circumference that would be and if it would go that low, but, go to the YouTube user SigmaSportUSA and ask them. They’ve been very good about answering my questions.
thank you so much!!! I couldn’t figure this out on my own.
To get the most accurate calibration do a wheel roll out. With the valve stem perpendicular to the ground, mark the pavement at the valve stem. With the riders weight on the bike, roll the wheel one tire revolution in a straight line and mark the ground when the valve stem is perpendicular to the ground again. Measure the distance in inch or millimeters (depending on your measuring type).
This is the most accurate wheel calibration number.
Hope this helps
