I went riding with four friends today. I am 6'1" 200# and was riding my touring bike with 700X28 tires at 100 PSI and Deore hubs. Two of the other riders were my size and the other two were quite a bit smaller. One was on a cross bike and the other three were on road bikes. We climbed a very steep hill and I was able to stay with them without any trouble at all. When we got to the top of the hill we stopped and all started at the same time. We coasted downhill about 2 miles and none of us pedalled during the downhill run. My bike is no doubt heavier than the others. All of them passed me on the downhill and walked away from me as we were all just coasting. I would have thought that because of my weight and the weight of the bike that I would have been the one going the fastest. Could someone please explain this to me. Were their wheels that much better? What am I missing here.
