Hi,

Today I have changed my original tires after 15000 km with the new Continental Top Contact II 26 x 2.
They are 0.5 smaller than the original Schwalbe Big Bens.
Can I change in the computer/controller unit the size of the tires to have an accurate speed and distance indication?
What would be the code?

Many thanks!

They are smaller only in terms of width. Even though top contacts are not balloon tires like Big Ben, the difference in height should remain within 5mm.
My back of the envelope math tells me that at the end of 1km ride, you may be off by only ~20cm.

Thanks Paolo. I'm going to write that down in my manual.

So for a 26x2.0 it would be 2056 mm
