Subject: RE: Ironman Louisville : Official ThreadI am assuming that these numbers are based on absolutely perfect conditions. I found this on the interweb: 404 front + 404 rear = 58-60 seconds/hour, i.e. savings of almost a minute 404 front + 808 rear = 68 seconds/hour 808 front + 808 rear = 80 seconds/hour 808 front + rear 900 disc = 92 seconds/hour 808 front + sub9 rear = 120 seconds/hour 808 front + 1080 rear = 128 seconds/hour 1080 front + 1080 rear = 144 seconds/hour Disclaimer these are Zipp's numbers and it is old as they no longer make the 1080.
