Sigma Sport Bicycle Computer - How to Set Wheel Size

Sigma Sport Bicycle Computer - How to Set Wheel Size I&making this video just so I won&have to find or read the manual again! My web site bike tire size calculator: I don&really understand this, but here are the wheel size settings I use (which are for MPH): 16x1.75x2 = 0790 20x1.75x2 = 0988 24x1.75x2 = 1184 24x1 3/8 A = 1210 26x3/4 = 1214 26x1 = 1225 26x1.5 = 1258 26x1.6 = 1274 26x1.75x2 = 1286 26x1 3/8x1 1/2 = 1296 26x1.9 = 1298 700x18C = 1306 26x1 3/8 = 1307 26x2.00 = 1313 700x20C = 1313 26x2.125 = 1325 700x23C = 1325 700x25C = 1333 700x28C = 1335 27x1 1/4 Fifty = 1350 700x32C = 1350 27x1 1/4 = 1366 28x1 3/8x1 5/8 = 1370 700x35C = 1370 28x1.5 = 1381 700x40C = 1381 28x1 1/2 = 1407 28x1.75 = 1409 The manual also has wheel size settings for KPH (and what I don&get is why these would be different): 16x1.75x2 = 1272 20x1.75x2 = 1590 24x1.75x2 = 1907 24x1 3/8 A = 1948 26x3/4 = 1954 26x1 = 1973 26x1.5 = 2026 26x1.6 = 2051 26x1.75x2 = 2070 26x1 3/8x1 1/2 = 2086 26x1.9 = 2089 700x18C = 2102 26x1 3/8 = 2105 26x2.00 = 2114 700x20C = 2114 26x2.125 = 2133 700x23C = 2133 700x25C = 2146 700x28C = 2149 27x1 1/4 Fifty = 2174 700x32C = 2174 27x1 1/4 = 2199 28x1 3/8x1 5/8 = 2205 700x35C = 2205 28x1.5 = 2224 700x40C = 2224 28x1 1/2 = 2265 28x1.75 = 2268
