GPS vs. Avocet 35: Which is more accurate?

Avocet 35 cyclometer compares favorably against the Garmin 500 for miles ridden.


Don’t expect me to give you an answer to this burning question. The Avocet 35 was one of the most accurate cyclometers on the market, and still is today, long after it bit the dust.

I calibrated my Avocet cyclometer before the ride, and measured it against a known distance to confirm. The tire pressure may have been off a few pounds.

The result on a recent ride with some rocky trail was 46.55 miles for Avcoet, 46.47 to the Garmin Edge 500.

I looked up the accuracy of GPS and came across Sheldon Brown’s description (speaking to us from the grave) of GPS, which has interesting details explaining why GPS can have some variations. A must read.

On a ride back in 2008, I compared the VDO with the ancient Specialized Pro. My Hecker Pass route totaled exactly the same distance of 95.72 miles!

Two of my favorite cyclometers matched perfectly on a 95 mile ride. Uncanny.
