speedo woes

[Black5]

I have been using a wireless cycle computer.

Everything going well, then one day my fitness must have suddenly and significantly improved.

The other week I maxed out at 83mph and averaged 72mph for nearly an hour of riding.

Could someone explain why I only travelled 17 miles?
I measured this driving the same route in the car!!!!

Is there any hope for the speedo?

Have you knocked the spoke magnet so that it's perpendicular rather than parallel to the fork leg sensor? If so it can give 2 pulses per revolution.

Other alternative: is the battery going in either the speedo or the sensor?

Magnet is fine, will check the batteries.

My wireless does strange things when the batteries get low, they are also very susceptible to RFI, not shielded very well.

My wireless does the odd starnge thing every now and then too.

TBH, i much prefer the wired cycle computers.

i gave up on them years ago for this reason, they were terribily inaccurate. Plus i lost them regularly... not the answer your looking for but consider a GPS based unit instead?

Have you started wearing a heartrate monitor? Does sound like batteries or interference, or has someone programmed it with the rolling radius from a pennyfarthing?

It also reads heart rate. This seems to be ok - I haven't died yet!!!!

Wheel radius is still set the same.

I've been using a Cateye wireless computer for about 4 months now, its been absolutely perfect ... but wouldn't be surprised to see it behaving erratically when the batteries get low.

Speaking of speedo woes - got to the bottom of a rocky descent in the dark last night to discover that the computer had managed to rattle its way out of the holder and was gone. Ar$e.

Coulda been something worse rattling .... getting to the bottom of a rocky descent and finding that the brakes had come loose ....

Indeed! Although I have done the same descent and then had Neil point out that my front skewer had come undone Thank god for huge safety dropouts on RS forks...
