Wheel Circumference

[Mike777]

Hi all

I have just brought a cateye mitty 8 and this size in not in the instructions

Does anyone know the wheel circumference in cms for a tyre sized at 26X1.6. The nearest in the instructions is 26x1.5 which is shown as 201 cms but having looked at some website 26x1.6 is quoted as 205cms ?

Many thanks for your time

According to my Sigma chart it's 2051cm, but I always use the rollout method ie. valve at bottom of wheel and mark on floor. Roll bike forward (keeping in as straight a line as possible) until valve is at bottom again and measure distance between the two marks.
