You don't actually need to, but it's handy if you're doing stuff where navigation is important, or long rides. Having a fair idea that there're 15km to go on a km ride means you know you can pick up the pace a touch and probably be safe. That's even more the case in the bush where buying an emergency Mars Bar and Coke from the servo is a bit tricky. Oh, and the sigmonster's telling me it knows the date, and wants an easter egg.
It took him three days to re-spawn Geez I'm a dopey bugger Wilfred. Kingsley Guest. Well, what's the point of having a computer at all if it's non-accurate?! Just use a piece of string on a map. Do you wear a watch? You might eat all that beer an pizza, and only have gone km! TimC Guest. It would be most satisfying when someone asks me for the time. I tell them, and then they ask, "no really, I need to calibrate my speedo". Vincent Patrick Guest.
You might want to use the fuzzy clock on your K Desktop then, and right-click to configure its degree of fuzziness to your liking. Cheers, Vince.
It probably takes longer to read the directions and enter the information in the speedo. Though to be honest once I have done it I rarely recheck it when I change tyres Regards Prickles Timendi causa est nescire This message only uses recycled electrons.

The first one i ended up finding a straight stretch of road and marked out a 1 km stretch in a new car and rode my bike back and forth adjusting the BC each time untill i got it to match the marked out 1 km on the road and found that to be accurate after about 5 kms back and forth.
With my new BC i thought they may have got i right but no , I did the roll out measurement of the wheel and went for a known 50km ride the BC showed that i had travelled 93 kms. When i set the old one up my top speed was a beleivable 43 kmh. Not the 63 that the wheel roll out method comes up with. I also rechecked the measurement incase i had miss calculated it was the same. The way iam going to set it this time is take a GPS and keep adjusting the BC untill i get the speed spot on. Will get back with results Joined: Jan 5, Messages: 2 Likes Received: 0.
The rollout test, in my opinion, is the greatest approach to calibrate. I have a Sigma sport as well as a CatEye. I didn't see anything was wrong until I got the CatEye.
The tire should be , the CatEye , according to the Sigma wheel chart, and my rollout measurement came up in Compare this number to the chart on page 15 in the Sigma manual see link in References section to determine tire size. Stand your wheel up on the ground. Measure the height of the wheel from top to bottom with your millimeter tape. Multiply the height by 3.
Input this number as the wheel size in your Sigma computer. Lay the millimeter tape on the ground. Place your wheel at the end of the millimeter tape with the valve stem at the bottom of the wheel. Why is the bike computer displaying the message "Low Bat" even though the voltage reading shows as 3V? How does Sigma determine if a battery is dead? The bike computer measures the voltage of the button cell under a defined load. The "Low Bat" message is activated when the total capacity falls below approx.
Can I change the battery myself without voiding the warranty? What can be the cause if the bike computer displays no speed? Bike computer is faulty. Incorrect speed displayed: - Is the magnet correctly positioned? What is the maximum speed that the bike computer can display? The speed is displayed up to How do I determine my wheel circumference? Conduct the measurement as follows: STEP 1 Stand your bike upright and position the wheel to which you want to attach the sensor so that the valve is directly on the ground.
Ensure that the tire is fully pumped up in accordance with its usage conditions. Mark the position of the valve on the ground with a line or adhesive tape. STEP 2 Push the bike forwards in a straight line until the valve is back on the ground again after a full rotation. Again, mark the position of the valve with a line or adhesive tape. STEP 3 The distance between the two marks on the ground is your wheel circumference, i. No, the new Topline 16 docking station product no.
This prevents undesired energy consumption during storage. To activate the bike computer, press and hold the SET button on the back of the housing for at least five seconds. The bike computer switches off automatically after five minutes sleep mode activated providing that no speed signals are received and no buttons are pressed.
On setting off, the computer will automatically wake up from sleep mode and switch on. If no antenna icon is visible, you must press a button. How do I attach my bike computer? Set-up videos are also available on our website. The wireless transmitter and bike computer should always be attached to the same side. Can I use my bike computer in the rain? What is the maximum speed that can be displayed by the bike computer?
