I have just replaced the battery in my sigma BC 1200 after a long period of not bothering what speed/how far I had gone etc. So out I went yesterday for a ride in the hills and was amazed at the improvement in my performance; shooting up hills at 24 mph and down the other side at 46!
Alas it's an illusion and the code for the wheel size must have reset itself. Does any one out there know the particular code for this comp for 700 x 23c tyres?
