Hi
I have just bought a MTB and fitted a Topeak cycle computor to it ,
Setting the cycle computor was realitivley easy but the trouble came with the wheel size which is needed to programe it,
These are the sizes on the tyre ,
57-559 .......26 X 2.10 which i cant find any feference to on the net for circumference.
The data on the sheet supplied reads 57-559....26 X 2.215 circ 2133mm
I roughly measured the Dia at 660mm X 3.14 = 2072 circ
Confused i am , can anyone help please . It may not make much difference one way or another , but i am always thinking it is lying to me .
I have it set at the 2072 circ
