Rear Di2 derailleur is finally done for; Yesterday’s “MTB” ride.
Before yesterday morning’s ride I put my Madone in the stand in an effort to diagnose the shifting issues that I was experiencing after Sunday morning’s mechanical. I’m glad that I took the time to do this, as it became clear that the Ultegra Di2 rear derailleur was in dire straits: the bike was clearly not safe to ride. After about an hour of messing with the derailleur, I came to the conclusion that it was shot.
I enjoyed 12,500 trouble-free and reliable kilometers with this derailleur. 12,500 kilometers may not sound like much, but I put the poor thing through two hard and very damaging wrecks. I believe that those two crashes did physical damage to the derailleur (the electronics are fine), and that physical damage is probably what caused the mechanical issue I experienced on Sunday.
Yesterday I pulled the battle-weary derailleur off the bike for the final time, and will be replacing it this evening with a brand new one (click to enlarge):
Here’s a look at the damaged cogs on the upper pulley, which I mentioned in yesterday’s blog (click to enlarge):
Finally, some of you have made fun of me for keeping such a clean and orderly bike shop. This photograph is for you (click to enlarge):
I know the work bench is not that bad, but it’s looked like that for about a week. That’s astonishing for me. I cleaned it up last night. 🙂
So, with my Madone out of service and my 2014 daily riding streak on the line, it was clearly time to get back in the dirt! I put my Fuel in the work stand and gave her a once-over. As I worked on my mountain bike, I realized that I was totally stoked about hitting the trails again–it really has been a long time. What can I say? The roadie bug bit hard.
Anyway, I got the truck all loaded up, excitedly jumped into the driver’s seat and, with a dumb grin on my face, turned the key… click. Dead battery. As I sat there pathetically willing the truck to start, I started doing some calculations in my head. I realized that it’s been a few months since I’ve traveled anywhere using any mode of transportation other than a bike. Oops.
I glumly unloaded everything from the truck, and did the only thing I could to keep my riding streak alive: a 50 kilometer road ride on my mountain bike. The Fuel felt like a tank compared to my Madone, heavy with slow-rolling knobbies.
I almost wrecked, too. Early in the ride I was descending a pretty steep hill, and I briefly let go of my handle bars as I instinctively shifted my grip down to the drops… which, of course, were not there. Crikey.
It was hot and windy, and I rode hard. I don’t have a power meter on my Fuel, but my average heart rate was 160 BPM, which is Zone 3 (Tempo) for me. When I finished the ride the heat index was 105° (F), and I was exhausted. Good ride, but I sure wish it had been in the woods. Today’s will be. 🙂
