hi ,does anyone out there with a sigma BC1600 (?) know what the code is for 700c wheels. I have lost my manual.
Best thing is to measure the circumference of your tyre - as all are slightly different.
Put a mark on the ground and roll the wheel for one revolution. Mark the ground and measure the distance.
700 x 23 tyres I use range from 2112 to 2120 mm
Hi, thanks for your quick response - i will try that
