This month I got a new aero frame, and I was excited to build it up from scratch. My Ultegra 6700 groupset has served me well for about 7 years now, but I felt like it was time to move up to 11-speed and Di2. So, when all parts were assembled, I was excited to put it all together.
Took it for its first ride yesterday and it was awesome… at least for the first 15 miles or so. Then I started hearing some weird noises from the rear derailleur when using larger sprockets, and then a disturbing, regular “clacking” coming from the drivetrain. First thought was that my new frame was cracking, and I was still 6 miles from anywhere. Then SNAP, the brand new chain broke! I had my phone on me, but I just couldn’t face up to the embarrassment of calling my wife (at work, no less). I managed to jimmy the chain back together and limped slowly back to safety.
So, despite my supposed wrenching prowess, I failed to properly put together the friggin’ chain. Ugh. Also, it turns out that the Di2 derailleur hangs a bit differently than my old 6700 did! I promise, the next time I get new bike parts, that I will make sure to read the instructions.
