I just received a Bontrager Trip 4W through my credit card reward program. It was fairly easy to set up (only slightly confusing) with the help of an online video & manual. The only thing i don't understand is the "flashing digit setting" for the ODO & what changing the values of the 5 zeros does. If anyone knows what this does, or what they count for (miles,ect.) i would like to know. Thanks. Tom http://media.bontrager.com/owners_ma...ip_1_4W_EN.pdf
