Shimano Di2 Re-Cable Project // Giant TCR Road Bike

Prior to the Festive 500 challenge I completed the re-cabling project I’ve been talking about for a while. This involved removing the Di2 Y-Splitter from the front of the Giant TCR and re-routing the left lever cable internally to the bar-end Di2 Junction A, making things look super-slick and much neater. I took the opportunity to also relocate the Di2 Wireless Module, switch over to Pro VIBE 38cm bars, treat them with Boeshield T-9 Corrosion Protection, and finally install new BBB FlexRibbon bar tape. The result was exactly what I was hoping for.

  1. Shane,

    This is totally unrelated, but wanted to ask what your opinion is on a Tacx Neo wear and tear on a bike.

    I’ve used my original Neo with my 2012 Madone, but just purchased a 2020 Tarmac Expert disc.

    I’d love to ride it, but we’re still months away from cycling outdoors in Canada.

    I’m obviously itching to ride it other than the 100k I got in before it became too cold, and adjust to the geometry difference, etc, but I’ve been told by everyone it’s not worth the wear and tear.

    So, two questions:

    If you were me: would your new bike be going onto the Neo, or would you only keep the older bike on it?

    How much wear and tear would you saw a disc bike takes from a Neo?


  2. Wow. I only have mechanical system but this video has convinced me if I go electric to buy sram wire less
