View Full Version : Sigma BC16.12 Wireless Computer Distance Accuracy?

July 1st, 2014, 03:20 PM
Just wondering if anyone else is using this computer and your thoughts? I have it all setup with the correct roll out for my Bontrager 29" tires. Rode a few sections of Bedford the other day and used it for the first time. Mapmyride came in around 4.04 miles, the Bedford trail map showed the distance I rode about 4.1 miles and the computer came in at 4.55 miles. I would think the computer would be more accurate than the GPS on my iPhone and I'm not sure how the distance on the trail map was calculated. I've had a friend use mapmyride at the same time and we have come up with over 1/4 mile differences riding the same exact trail.

Any thoughts? 1/2 mile is pretty substantial under a 5 mile ride.
