Hi – how does it make sense that 16 x 1.

If you look at the tird tire circumference reference guide, http: Let me know thoughts. My only reference for using was Sheldon Brown’s chart.

You may be correct that the Brompton’s wheel circumference could be smaller than However, since using the code, the reading has been quite accurate. Do let me know the real wheel circumference when you know. Hi Catwye, I bought a cateye wireless strada recently for my bike as well, and I stumbled onto your website while looking for the answer to the same question that you asked since the manual did not have a computation for the Brompton’s tyre configurations.


Guess the debate is resolved!

Hi there I’ve measured the circumference by wrapping inch-tape around the wheel and I got mm measured 3 times, with the tape pretty tight That’s close to what you can find in here: I’ve forgotten to say that I have Schwalbe Marathon tires.

So, am I doing 23mph, or only 22?

I gots to know man. Just measured a fairly new Schwalbe Marathon at mm. Didn’t take note of the tire pressure but tire give was minimal.

Just measured a new Schwalbe Marathon at 75psi one circumference along the ground and I get Pages Home My Bikes Dealers. After much procrastination, I finally decided to use it. A problem came up, though, in inputing the wheel circumference [L mm ] unto the computer.

Fortunately, there’s the internet. So I entered that in the Cateye Micro Wireless and rode the acteye to test if the code was correct.

I biked to a place which I knew was 1 kilometer from my house, and when I got there the reading was 1 kilometer. It was useful because I knew how fast I was going, my pace, and the time and distance I covered.
