Sorry for the crosspost, but I'm looking for help.
I'm on my second 2013 TCR Advanced 0 after returning the first due to excessive and incredibly distracting amplified rattling from the downtube.
It seems a minor nit to pick, but it is almost maddening hearing this road texture clatter. If I'm riding on anything other than perfectly smooth road surface, the rattle is constant.
The LBS was incredibly awesome and swapped out for a new frame, but the new one has the same problem, if slightly diminished.
I've been led to understand it's the Di2 cabling / cable ties, but I promise you the 2012 that I test rode had no such rattle, nor does my wife's 2012 Avail Advanced 0 with the same Ultegra Di2.
I'd like to know 2 specific things, if there are those who've observed this problem.
1. What is the loose piece that's rattling inside the downtube?
2. How can I make it stop?
Thanks for any advice!
