Being a techie guy, I felt the need to add more to this thread.... Imagine
you are riding 20 miles per hour. One tenth of an mph is one part out of
200 of your speed. There is no way that this is meaningful data. The
computer might show it to you, but it has no connection to reality.
Bike computers only measure your speed when the magnet goes past the sensor
on each wheel revolution. The computer only reports this speed to you every
couple seconds, so the display does not change too fast. The computer does
this by taking an average of the last few wheel readings. So the display
you see is really your average speed over the last couple seconds. During
this time, your true speed has certainly varied by far more than one part
in 200.
In technical terms, speed readings of 1/10 mph are PRECISE but not
ACCURATE.

Quoted message said:I'm looking for a new cyclocomputer; so far I can't find one with the
functions I want. Besides the basic functions, it MUST have cadence,
and it must have a "pace arrow" (showing current speed above or below
average). Also the current speed should display in 1/10 mph increments.
The Sigma Sport BC1600 has everything except it displays in 1/2 mph
increments.
Wired would work better than wireless - it will mount on an aerobar mount
and many years ago that caused a problem for me.
Anyone know of one like that for less than $50? I know the ones with
altimeters and such will have all that but for too much $$.
Thanks,
George
