Sigma Sport Sigma BC 9.16 ATS Fietscomputer, zwart, één maat

Balen verkopen oude troep. moest direct 2 batterijen kopen omdat ze allebij leeg waren 9 euro uit coulance 4.95 retour.

Tijd loopt niet goed op tijd. Verloopt steeds. Sensor kapot na een half jaar.

Even wat problemen gehad met de montage op de voorvork i.v.m de afstand met het magneetje maar nu doet ie wat ie moet doen!

Doet wat het moet doen, ideaal voor beginners zoals ik.Makkelijk te installeren.Je krijgt alle basisgegevens mee, voorlopig niet meer nodig.

Très compliqué, non merci.

Just the functions I needed. Normally I show time and speed while on the road and then check distance and other things when I am back home. Perfect and easy to set up and understand.

I already had the non-wireless version of this speedo/computer on my touring bike (vintage Dawes Galaxy) for the past two years and really liked it, so when I bought a mountain bike I wanted a similar one. It's a no-nonsense, small, lightweight and accurate speedometer/odometer that is easy to install and easy to remove when the bike is parked up.I decided to buy the wireless version mainly because it would eliminate any problems with cabling down the suspension forks.Apart from the sender unit this looks and works identically to the wired unit on my Galaxy. The tiny head unit simply twists off the mount for quick removal when leaving the bike parked.The sender is relatively big (it houses a second coin battery as well as the transmitter) but it fits very solidly on the fork just above the brake caliper and under the brake pipe. It might even help to protect the brake pipe from twigs etc. I used both the included rubber O-ring and tie wraps for a belt-and-braces approach, and it hasn't moved at all in the 50+ miles of mainly technical trail riding that I've ridden with it so far.One minor niggle I've found is that I have to make sure the unit has 'woken up' when I start to ride - the connection goes to sleep and needs to be woken up by pressing the button, presumably to save the batteries. A symbol on the screen indicates when the connection is live.Another niggle is that the trip readings (ride time, average speed etc) can reset themselves if you stop, or the unit thinks you have stopped, for more than a few minutes, which has happened when I have had to push and/or carry the bike very slowly over unrideable terrain!I've given a 5* rating for accuracy even though I haven't actually tested it because, instead of using one of the presets, the device allows you to set a very accurate figure for the length of one wheel rotation, which I did after measuring it by rolling along a tape measure with my full weight on the bike, thus allowing for tyre deformation. Given that all the measurements are based on wheel rotations and time (apart from calories, which are pure conjecture and I've ignored), I assume therefore that if my measurement was accurate then all the computed measurements will be equally accurate.I can't confirm the battery life yet, but I can say that the non-wireless unit on my Galaxy is over two years old and still on its original battery, so the omens are good.In short, highly recommended.

Too small yet fits for purpose.
