I simply couldn't wait for the warm weather to ride my new HiFi so with my son we geared up and rode about 6 miles to a local ski area. It was nippy but I so enjoyed my first ride on this this fabulous new HiFi. I was mostly checking out the fit and enjoying the shifting and hydro disc brakes. I hardly notice the cold! But my son was having trouble with a pretty stiff and cold head-wind so we turned around. I am going to try and ride some everyday that it isn't icey or snowy. Overall, I really like the HiFi. I am not sure it is dialed in for my size yet but will ride a bit more before tweaking it. We spent a lot of time at the LBS getting as best we could.
