[QUOTE=igloomaster]YES!!! OK, this little dumb arse (me) figured it out.
The tech at the bike shop had my cyclometer set at 2070 instead of 2170.
Which translates to this: The Cyclometer thought my tires were 700x18 instead of 700x30.

Thats less than 5% off. I dont know why everybody gets so concerned about the accuracy of their computers. I like to know how todays speed compared with yesterdays and my PB. If you want to brag about your speed and distance set your roll out to 2370.
