Hi, I just purchased a Sigma BC906 bike computer and it installed very easily and the set up went good as well until I got to tire size setting.

My tires say 26x2.10 on the side and in the booklet that came with the sigma that size is not listed, what is listed is 26x2.00 which gets set at 2114 on the computer and 26x2.125 which gets set at 2133.

is a 26x2.10 tire close enough to a 26x2.125 to use that setting? do any of you fine people know what the setting should be on a 26x210 tire? I was thinking of just shaving a couple numbers off of the 26x2.125 and like setting it to 2125 or something like that, would that be close enough to be fairly accurate? or am I missing something.

any opinions and or suggestions are greatly appreciated.

As Ever
Me
