Went riding just before noon. The weather was unusual today. In the first part of the ride, the wind was from the north. Then, on the return trip, about the last 1/3 of the ride, the wind went the opposite direction. I probably lost about 5-6 minutes because of the opposing winds. So, today was a little interesting with the the Di2. It labored on the downshift in th rear. So, I tried to adjust it, but it made it worse. So, when I got to SS, I tried again to adjust it. This time, it worked. Not sure why it was having problems to begin with. But it seems to be dialed in now. I'm reluctant to buy a new Cassette and Chain, but if it comes down to that, I suppose I will. All other components working flawless. Ailments, no soreness in the knees. Some soreness in the lower back, so I was continually stretching it when it became too much of a hinderence. There was some numbness in the right hand. But changing positions fixed that. I had pretty good concentration today, almost no lapses. Balance was good, I think I have that dialed in now. Bike, there was some creaking, but I'm almost certain that it's the wheels. Better the wheels than the frame I guess. They're not out of true, so I'm not sure exactly how to fix the problem. Will just have to keep an eye on it for now.
