SBP glad to see your able to get out, frozen water just means you suffer more (Suffering is good). I was going to wait until the start of 2011 to switch over to my other Zipp but decided to start a tad early. With the holidays and everthing else I hope to have Zipp #2 finished by Feb. sometime. So I'll have to live my cycling thru you during the winter season, remember we like hills. Keep me posted how my riding is going (LOL).
