Thankyou. For once I didn't have to post this site first.

This site has been very helpful in the past for doing certain preparations for different events on different terrains. For instance, I was torn between taking my tailfairing with me on a 7 day tour in Tennessee. I was worried that the extra 6 lbs worth of weight would hurt me on the long climbs. After plugging in some wattages with the stock bike setup and the tailfaired bike setup on different grades, it appears that the extra weight of the tailfairing will on the average only slow me down by .2 mph at the most.

The benefit will be on the flats where I can gain 5-6 mph over the stock setup. I'd rather cruise at 28 to 30mph on the flats and pay a .2mph penalty on the uphills.

oh, if you want to get faster on a downhill, try one of these.

on a -5 percent grade, a 200 lb rider in the drops will reach a terminal speed of 35.7mph

on my tailfaired lowracer on the same downhill 5% grade I will hit 56.1 mph

( been there done that) many times
